So much for beating the iphone...

I hate Apple with a passion and I was rather excited to have a viable (superior) alternative to the iphone with the Touch Pro2. Everything about this phone has been fantastic until just now when I plugged in my headphones. I'm something of an audiophile and thus use some decent headphones. In the course of my listening, here are my findings:
The Touch Pro 2 performs great with less sensitive headphones (like Beyerdynamic DT770 80ohm), but with sensitive headphones like Grado's it sounds like CRAP.
Even more disappointing, using sensitive high end earbuds like my Super.Fi Pro 5's reveal SIGNIFICANT and DISTRACTING electrical noise. If you listen to quiet music like some classical or jazz, you will definitely notice it. While annoying, at least with music, the music itself usually overwhelms the noise.
Unfortunately, watching a video is a completely different story. In short, watching a video on this phone is like Chinese Water Torture with the electrical noise easily heard 100% of the time.
It's simply unacceptable for a manufacturer to produce a device in this day and age that has this kind of interference. They should really test a $500 device with earbuds that cost more than $10.
The whole point of this phone is for power users, and power users like us are the exact demographic that would have expensive (usually high sensitivity) headphones.
The noise is worst in the left channel.
This is on a Verizon TP2 for reference. Is this possibly just a defective phone or do others experience the same noise? FWIW you probably won't notice it with normal ibud's.

I have a pair of Sony MDR-EX71SL Fontopia's and dont have any issue with device feedback or interference. While they arent as nice as your headphones, they do a pretty good job, and have been a fantastic match on my Sprint TP2. Video/Music, no difference. I did tweak the equalizer a bit (Audio booster in programs menu), but that was for personal preference, and my music tastes.
What add-on programs have you installed? There could be something that got screwed up...
Otherwise take it in to the store with another MP3 player that has the same mp3 on it as your tp2 and have the rep listen to both, and ask to try it on a demo phone they have there, I'm sure they'll fix you up.

Hmmm, your Fontopia's look like they only have 100db sensitivity rating compared to 119db of my headphones. That could be why you don't hear the noise (please note that I'm not putting down your headphones, as sensitivity has very little to do with actual sound quality - it's simply an electrical measurement).

I can't hear any noise on my Sennheiser eh150's, nor on my 6.5" component speakers in my car.

Well... I'm surprised you would expect good sound quality from a device aimed squarely at the business market. The iPhone is designed for multimedia and does some businessy stuff on the side. The TP2 is designed for business use and does some multimedia stuff on the side. The performance is what you would expect, given that goal.

If I want to listen to music I pull out my mp3 player and Shure's.

Well that sucks your not happy with the audio quality. I'd try to check the same song with your buds on another persons phone, and rule out a faulty device.
But if its not specific to your device I guess in this case more expensive isnt always better.
I'm very happy with the sound quality of my Fontopia's, I have a 16gb gen 2 ipod touch and I there is no quality difference between it and the TP2....

Absolutely no noise-floor issues here, using Shure se530s. In a direct comparisonj between my TP2 and the 3GS I would say the TP2 is easily as good, if not better.
Sounds like you have a faulty phone. Not to be patronising but did you try a different USB/3.5mm adapter? I had one that was very "crackly", swapped it and that was perfect.

Okay, your shures have the exact same sensitivity as my UE's, so it should be able to pick up the noise. Have you tested with video using HTC Album?
What about background hiss while music is playing?
My phone is starting to develop the oil slick problem so I might just swap it out anyway.

Also, just a note, the Verizon phone has the 3.5mm jack, so no need for a dongle. Internally though, I do wonder what the electronics look like, and if it's just a hardwired (though smaller) dongle.

I use the Sennheiser CX300-B ear buds and can definitely hear background hiss. I can hear it when I initially plug them in then, if I don't do anything the hiss goes away until it plays something. Sounds like when the amp turns on then I hear the hiss. I hear it for music, voice prompts everything. You can hear the same thing by pausing the music and you will hear a hiss for a couple seconds, then it goes away.
When I have music playing I cannot hear it, but do hear it during the quiet times of the song.
I've found this to be true with these earbuds for pretty much any player I use that is not dedicated to audio only. I always figured they just do not spend the $$ to put in good audio capabilities in the multi-use devices.

If I listen to the FM radio I can definitely hear interference, usually listening to NPR (talk radio). Though not sure if it is slightly less then perfect reception or an actual sound issue. I feel as though the mini usb connector is less then ideal. It has a lot of wiggle. Wonder if that is part of the problem.
This is with the factory ear buds.. have yet to really listen to music on it, or with good ear buds.. or through my car stereo(where I usually listen to music with my phone)
OK, after typing all that I guess I am not sure if mine has this problem! LOL But I will leave this post here so I can update it after I use the sound output more.

I think it is laughable to use the word audiophile and earbuds in the same sentence.
Your best headphones for monitoring are over the ear
Don't have any issues with my Verizon unit. I have hooked it up directly to RXV3800, Sennheiser HD380, and M-Audio DSM2 and hear nothing I have not heard with other MP3 players including the ipod.

I noticed my Verizon TP2 had flatter sound than my mp3 player with the same phones, but after a little EQ adjustment in Nitrogen, they sound just fine.

You guys have way too much time on your hands to complain about those things.

I find it's laughable that you don't know what you're talking about.
My earbuds are every bit as good as your headphones, and earbuds exist (like the UE11) that obliterate even the best studio monitors in detail, frequency response, linearity, immediacy, transient resoponse, etc. In fact, they obliterate studio monitors in literally everything MAYBE soundstaging and impact.

Besides, you completely missed the entire point of the thread by saying "Nope, everything good driving my low sensitivity headphones!"
For the umpteenth time, you will not be able to hear this noise with low sensitivity headphones (as I confirmed with my DT770's). This problem only relates to driving high sensitivity cans.

This confirms what I was saying. The sensitivity of your earbuds is 112db, which is far higher than the other posters 100ish range.
It would appear that this might not just be a defective phone that I have, and that it could actually be a more widespread problem.

Except that he claims to hear it on several devices, not just this phone. Also he claims to hear it only during the quiet parts, not during actual sound reproduction, whilst you hear it at all times...
It could be the adapter, a faulty phone, or just a phone not designed for high-end hedphones.
Good luck with this. I love high quality headphones but use bluetooth to listen to music (yes, I hear the difference, but when I have cables they always get wonky and stop working properly).
Now if the phone had KLEER technology I'd happily go for that

This sounds more like thread on bragging about your super duper headphones than anything to do with the TP2.
But maybe they arent so super duper if cheaper ones sound better.
Get past it, if you want a dedicated music player that lets you become immersed in 1024bit crystal clear audio go get whatever that is.
If you want a music player that sounds pretty damn good, can also take phone calls, browse the web, manage your schedule, send/receive emails and txt, take pictures, go buy a cheaper set of headphones.

why use expensive earpiece
why use all that fancy stuff .. can you really hear a difference? whats wrong with the set of stock headsets that come in the box with the phone?

Headphone Discussion for your EVO!

Hey everyone,
Long time lurker, first time poster. I'd like to start a discussion on the various types of headphones that everyone has bought for use with their EVO (or other smartphone) and what their thoughts were - got any suggestions for EQ apps, settings for each type of headphone? Which ones work best for you? Which built-in controls are the most natural for you? etc etc etc.
So, I'll start.
The first thing I want to say is that I acknowledge there are a ton of places the audio could go sour between the original media (CD, DVD, blu-Ray, etc) to the final product coming through your headphones. The whole process will go like this for a typical user:
Buy CD
Import CD using audio program (iTunes/WMP/MediaMonkey/CDRip)
Put songs onto device
Listen to device with music app (usually stock)
Your mileage may vary (you may have your own custom extraction settings, bitrate settings, encoder settings, music apps, etc etc etc), but I want to focus on not necessarily the most accurate sound possible, but the most practical and "best-sounding-to-the-untrained-ear" sound. Personally, I have my own settings, and I have something of an affinity for music encoding and playback, but most of my friends are happy with Skullcandies (*shudder*)
So, after an extremely long ramble for the first, I'll tell you about my headphones:
1. Sennheiser HD280 Pro Over-The-Ear phones
These phones are great, and now sell for about $90 cheaper than when I bought them. They provide a nice sound, and even response using the stock app. I can adjust settings from DSPManager and they sound even better. However, as I've used them over the years, the sound has decayed slightly to become more "middy" and they don't have the original shimmer they had before. Also, they aren't very useful for travel, but they're great for listening at home with, although the big "pigtail" twisted cable looks strange hanging out of your pocket.
2. Klipsch Image S4 Enhanced Bass Earphones
A nice pair of in-ear headphones, they provide a colorful sound and nice overall response to a wide variety of music. They're a relatively cheap set of phones (probably for the holidays) and they sound great. Again, messing in DSPManager I can get an even better sound. These are very comfy headphones and look great, they feel great in the ear, provide nice isolation to keep the music in your ears and the outside out.
3. Sennheiser CX-300II-B Earphones
My favorites so far. I just got these a little bit ago at a bargain price ($30), and I haven't looked back. For being such small headphones, they provide a powerful punch and a great sound. They can take loud volumes with no distortion (until you add EQ). The fit is comfortable, they have a Y-shaped cord (so the right ear cable is longer than the left ear). They stay in place, and look great. They came with a nice magnetic case that keeps the buds safe and secure and super-portable for travel.
4. Sennheiser CX-300-B Earphones
I have these phones also, and they are almost identical to #3, just not quite as bassy.
I have some other phones, but they aren't worth mentioning (Apple headphones, skullcandies, and some other cheap ones). The sound just isn't good, even after significant modification with EQ and such.
For my music app, I use the "stock" app that comes with CM6.1 RC1, and I EQ with DSPManager. Lately, however, I've started using powerAMP (AWESOME APP - Look for it in the Market), the built-in 10-band EQ w/preamp is a must-have in music apps.
I know this is a lengthy post, just wondering if you all have any favorite headphones/music apps/eq settings for headphones?

Well my dilemma in using headphones is that I pretty much always need to be ready to take a call at any time and you can't take calls very well on stereo heaphones.
So, not being much of an audiophile I just pipe pretty lame music into my bluetooth headset using Super BT Mono software. It sucks for music but will do for talk radio.

I have a pair of Shure SE-115's. Didn't buy them, thankfully as the retail was around $130 at the time. Got them through a points system at work.
They are by far the best headphones I have ever had. I ride a motorcycle everywhere, and these are the only headphones I've ever had that can almost completely cancel out the sound of the bike at city to highway speeds.
They sound excellent in normal conditions as well. They have awesome bass and clarity, and they fit quite comfortably.

I have a pair of Shure E5Cs (I think they are called SCL5s now), a pair of Shure SE530s, and a pair of AKG k240s.

Can anyone recommend a a good pair of over the ear (not over the head) headphones with headset controls and a mic?

I loved my Shure E3Cs, but hated the cables. I really like my MEElectronics M11p+ set, especially the cables. The Shures may have sounded a touch better, but only slightly, and you can't beat the price especially with a coupon. Actually just won a set of their M6p phones, so I will see which ones I like better and keep the others as backup.

I use the M-Audio IE-30 and they sound fantastic on my EVO.

I use my Dr. Dre beats pro with the MIUI music app on my EVO, I have also sanded the back so it matches nicely with the evo and pros. I also have the 3500 mha battery from ebay with Calkulin's EViO 2 ROM v1.6.2 and I get over 25 hours with heavy usage and music and game playing. The Pros are about 400 dollars plus insurance and tax 500 from best buy. If you are rz member next Sunday they will be 350 during the special event sale. Hope any of this helps. Also I added my own icons and can be found here to match dr. dre take a look. http://forum.xda-developers.com/showthread.php?t=793055

You should try the Halo headset. It's sweeeeeeeeeeeeeeeeeeeeeeeeeet

Samsung Supplied headphones, Volume+

Ok, so do these things just suck or is it something a good EQ could fix? they seem muffled and sadly my Klipsch headphones were the victim of my electric seats in my car so I don't have anything to compare them to. It seems like they sound better on my G2X, but Volume + seems to work on the G2X where it doesn't on my Galaxy S 2.
Oddly the free version of Volume + does seem to work, but it has no EQ settings. Anyone else noticed any issues here or have any advice?
Music is a big part of owning an android phone for me, if its gonna sound like crap over headphones then I'm gonna be hurting.

PowerAmp has some very nice EQ presets and controls. Now with Version 2.0 it is even better. I guess that Jugs ROM has DSP too for some sound tweaking.

Guess I'll DL DSP manager again I paid Volume+ and it was a great app for a while, guess I got my $0.99 worth for sure.

actually for once, these are very nice premium quality earplug headphones and functional, compared to previous ones from past phone releases, that were of low quality

And they don't sound muffled to you on the Galaxy S 2?
I think they sound better on my LG G2X so it makes me think it's a phone issue. I know it's not ROM as it carried over from the stock ROM to Juggs 1.1

what you are describing might the the audio chip people are complaining about all SGS2 using the yamaha instead of the worlfram whatever chip
have you tried hooking up the earplugs to another player?
i usually stream my music to by Stereo BT headset or car BT player

I don't like tons of treble, and especially hate the mid-highs. Compared to other OEM headphones bundled with phones, they're top notch. If you use SRS HD Audio Lab on your Windows computer, you can get some serious kickin bass out of them, bump up the highs and remove a ton of harshness.

i hate this type of headphones they just keep falling out of my ears lol...... I rather use the standard round ones from my htc lol

i too have small ear holes, so i can only use them for short periods of time, and when i'm not moving around, else they comes off on their own easily
i always buy the over the ear type, those that hangs on your ear
or simply use the big studio headset style which gives WAAAAAAAAAAAAAAAY better sound quality.
in that remark, seems like Sony is now being over taken by skullcandy
you see them EVERYWHERE these days, subway, bus stops, school yards specially, some work places, etc.
if you see anyone using a Sony, it's like WOW! a needle in a haystack
other brands like the german Scheiner (whatever spelling), those are also rarely seen in public now in days

I actually think these are decent earbuds. I use them from time to time on my laptop. I have some better quality sony ones that I use with the gs2 though.

can anyone provide me with the controls for the headset?
(ex: press twice to ff a song, etc)

My new Audiophile headphones problem.

Hello, I am very much kind of headphone lover guy.
Recently, I bought Beyerdynamic DT770 Pro 32Ohm (32Ohm version for portable users).
But the sound is not coming to its best. I plugged the same headphone to iPhone and it's working awesome. iPhone quality is same as it work on macbook and PC.
So, I was worried, is my headphone supportable on my Nexus 5 or I just have to invest in buying mp3 player.
I will provide link, where you all cann see the specifications and tell if that is supported on this device or not, because I am not that much of technical guy.
Headphone Link - http://north-america.beyerdynamic.com/shop/dt-770-pro-32-ohm.html
I have rooted my phone and is currently running on ElementX kernel and Chroma ROM.
Hope you guys can help me.
Thank you.

Is it quality that's bad or volume level? Or a bit of both?
Sent from my Nexus 5 using Tapatalk

More of a volume. The quality is good.

Try this - https://play.google.com/store/apps/details?id=com.n5rvb.nexus5realvolumebooster
Also i always use poweramp with the preset set on rock. Always find it the best sounding
Sent from my Nexus 5 using Tapatalk

Install any kernel management app, like kernel adiutor, and in sound menu raise headphone gain.

So I just did what you said. I already have paid version poweramp and installed volume booster, set it to 19 and 95 for headphone and speaker. Set my present to rock, but I was just little curious, are you also facing a little distortion in the sound or just me? Because I think, I can listen the distortion, maybe because these are kind of Audiophile headphones, so they are giving deep detail of every sound.
As far the volume matters, its 2.00AM, so very much silence environment but I can definitely feel the volume is increased.

How much did I set the headphone gain too?
I already installed the volume booster app, should I also gain on this app too?

Try these!!!!!
These are the "loudest" and best in-ear buds you can get!!!! http://amzn.com/B00WI79EK0 They are Zorloo "Z:ero". Forget about booster apps, eq apps, etc... This thing has a inline "DAC" it plugs into the "USB" port and not the 3.5mm jack. Read up on it!!! I have wasted money on many in the ear, over the ear, everything under the sun to get the best sound and these are my latest find. (Thanks to an article about the Nokia 808 and how people are pimping them out). I cant say enough how LOUD!!!!!!!!!! they are.
YOU WONT BE DISAPPOINTED!!!!
I think they are lurking under the radar because its not a "Brand" name like Shure, Whitestone, or any of the "high" end stuff people are used to paying 100's of dollars for. But the technology using "DAC" has been around and if your looking for something to drive your "over the ear" stuff maybe a usb cable micro to mini adapter and then a USB DAC Stick might work for you... I am sure you can also try to "hack" the "Z:ero" by cutting off the "ear buds" and then going to the local "radio shack" and getting a 3.5mm stereo input jack and soldering the four wires to it and you just made yourself a custom low cost "DAC"...
Just a quick review I google...

Install viper for android. It helps with the sound processing on the N5 immensely.

I was going to say something about the impedance, but my headphones are a higher impedance than that 35ohm, and I'm pleased with the quality and volume. I know you are not looking for just volume, you are looking for volume and quality. Something I found in the past with some of the Android EQ settings (didn't matter which app) some of the settings like bass boost, would actually lower the volume coming to my headset.
A good set of headphones shouldn't have to have any EQ settings changed at all, leaving it on flat should be the best, and for preference, you can always use flat as a reference.

Every headphones is different from others: if you want a boost in volume/quality, you should try an amplifier like FiiO E6 (http://www.amazon.it/FiiO-E6-Amplif...6?ie=UTF8&qid=1439893840&sr=8-6&keywords=fiio )
32 ohm is a bit high for a smartphone, so there is a possibility that Nexus can't handle that well.

I have a pair of 32 ohm dt770 as well as 32ohm mmx300 Beyerdynamic. They both work fine.
They definitely shine with a good headphone amp, but if you're running without one straight to a phone or laptop, definitely get 32 ohm. It's the lowest they make for mobile type uses.

Anyone knows which headphone goes well with this handset?

Being having the Quad DAC onboard, I really like to take the best out of it. So, I started getting some 24 bit FLAC format audio music files and listened to it on my phone. The B&O in-ear thing that comes along with the phone is pretty sh!tty. Actually it's not even B&O. I even cannot find it in B&O's catalog. I'm quite disappointed. So I tried my old Monsters Beats Solo (the original Beats Solo) next, nothing much different. The music is a little bit louder and clearer than the B&O in-ear phones but nothing else apart from it. Then I noticed that in the Hi-Fi Quad DAC settings, it just showed as "Normal Device". hmm ... is that really just a hyped about the audio? Then I grab my Plantronics Gamecom 380 from my desktop and plug it into my phone. That one is not meant to be paired with the phones. it's dual-jack gaming headset with boom-mic that meant to use with PCs. There the whole thing changes. Hi-Fi QDAC setting shows the headphone as "High Impedance Device" and yes, only then i can feel the real difference that the QDAC chips produces.
So now, since I can't bring out my Gamecom 380 to use with my phone all the way along. What's the best headphone that'd get the best out of the QDAC chips yet don't drain the battery like a thirsty elephant (and of-course without breaking my wallet much)? Please share your ideas.
