headphone audio gain

Hi guys
I would know if there is solution for boost the audio with headphone connected at the phone
thanks

To me this is a major flaw of the defy so far. I can hardly listen to my music when I am walking outside and I really don't understand why the volume is so weak when using the headphone

get better headphones?
Hi, I'm using the Sennheiser CX 200 Street II (excellent price for the quality) and I never use more than half of the volume. So, good inear pieces (those with rubber tips) might help
PS: Please don't tell me you're using the stock headset! They might work for one or two calls but not for enjoying music.
PPS: Does anyone know a compatible headset adapter? I mean one with a built-in mic that allows you to use your own headphones without the need of a soldering iron

As far as I noticed with my girlfriend's ipod touch, she can use my headphones to make skype calls. I can only suspect that they work the other way around. (her headphones are far but I might use someone elses iphone headphones tomorrow)

The iPod/iPhone Headset works, as I read several times. Unfortunately, you can't use your own headphones with that headset. Know what I mean? I'm looking for something that provides a mic and a 3,5mm jack for headphones
€: Finally, found what I was looking for: http://cgi.ebay.de/e12i-Stereo-Head...812849?pt=PDA_Accessories&hash=item3f064f7f31 I hope the quality is not so poor.

I use the music app Poweramp. Apart from being the most comprehensive music app there is, it also has a built in software amplifier to boost volume. I highly recommend it, definitley an app worth paying for.

One of these days (I'll have to go buy a 3.5mm socket) I'm planning to give an old Nokia 3.5mm set of headphones a new life. I only have to study how the mic/button work (might be some different resistors involved).
I'll get back with a how to after I'm done.

Anyone try the ZaggSmartbuds for www.zagg.com they have a 3.5mm jack, inline mic, inline volume control(analog). i normally use my SD9-HD bluetooth headset when listening to music but sometimes I prefered to be wired. Have been considering the Zaggs real hard.

But exist some head phone with mic and noise reduction function all in one?

Well... the ZAGGsmartbuds, the iPhone inears, the bose headset, the V-Moda Vibe
II w/mic...

I have found this
http://cgi.ebay.it/ZAGG-SMARTBUDS-N...UK_Mobiles_Accessories_RL&hash=item5d2d8b12e4
but I have read in the footer ad there is wrote this:
"Some non-US smartphones, such as the Samsung i9000, have a unique jack configuration that requires an adapter for use with the ZAGGsmartbuds."
So, for My Motorola Defy (France) could be some problem with this headphone??
thank's guys

We might have a different cable configuration at the jack, but we'll never know, if no one tries
PS: I'll tell you if the headset adapter that I ordered via eBay works for the european Defy and how it works.

I was more thinking of some kind of software solution to amplify/unlock the Defy's volume (I guess it is limited for health reasons).
The ones I found on the market just don't work.
I do not intend to buy a new headset as I use it 5-10 minutes a day at most.

Try the poweramp music player. It offers a graphic equalizer and the opportunity to amplify the volume. Remember: too much amplification results in bad sound.

Improved sound quality with fiio e6!

I bought a fiio e6 on amazon and sound quality has improved tremendously. Even with my a2dp receiver in my car, the improvement was great. Any other experience?

What kind of headphones are you using? i suspect that makes much more of a difference than the amp

I'm planning to get an E6 by the end of this month. Together with AKG K240 MK II. I will need the amp anyway, but it'll be good to know what ear-/headphones you are using.

Just tried my E6 on my i9100. Absolutely no change at all. Tried 5 different IEM's and 2 different headphones, they all sounded the same.

Maybe your E6 is broken!
I use it with akg K317 and in my car with a beewi bba100.

I've ordered an e5, which I should receive tomorrow, from what I've read the bass boost on the e5 is better than that of the e6.
I'll report back on any change on the sound quality, although don't expect anything in-depth, I'm no audiophile

without a proper lineout from the phone, the sound will either be same or worst in most cases. Because what youre doing is amplifying an amplified signal. So, if the amplified signal from the phone is bad, i'm pretty sure your external amplifier cant fix that.

You would need the Samsung official car dock for true line-out audio. Either that or make your own cable like the one here: http://forum.xda-developers.com/showpost.php?p=20710266&postcount=14
Maybe Bluetooth audio would also work, if you have a Bluetooth receiver with a decent DAC.

No matter what you use, it will not improve the overall sound of the device as it uses a cheap and crappy sound card. Any sort of amp including the Fiio E6 only brings EQ to the music, not to mention you actually lose sound quality because your using a jack to jack method unlike the iPod where they have special cables that connects directly into the DAC of the iPod because of the special provide cables which over-passes the direct headphone jack port. (Search up Fiio L9 Cable) Also when using the jack to jack cable that's provided with the Fiio E6 it lowers the loudness of the sound when connecting via phone to the amp.
Of course then there's the human ear, if you feel like it sounds great, good for you but in reality the sound is worse with EQ added to make you think it sounds great.
If your an audiophile you have to accept that the SGS2 isn't the best music device. Cowon for example or the SGP are good sounding music players. It's a waste of money to buy a Fiio E6 Amp unless your using an iPod to be honest cause it significantly improves the iPod devices.
That's my 2 cents, take it or leave it as you wish.

Yeah, I noticed no change in sound quality with my e5. However it can make it a LOT louder, so if that's something you need, you might still want to consider getting one of these

The galaxy s 2 does also have line out which bypasses the headphone jack (for example the samsung car dock does line-out over the micro usb port) but there doesn't seem to be anything available to buy to do this without the dock. However as claimui said you can make your own cable too

FM Transmitter

Hello, I'm looking for a FM transmitter for my phone that I can use with my car. It has to be inexpensive and I only want that particular device, not one of those DVD products. Does anyone have a product in mind that they use? Can you charge with it as well? Thanks.

VR3 FM transmitter works great. Tried a.couple others but they were staticy and volume was low...only use vr3 now.
Sent from my T959 using XDA

I have a scoshe (probably spelled wrong)and I've tried an as seen on TV one, (I think it was Jupiter jack). I'd recommended you avoid those and, I never use it cause of lots of static. It made me miss my old cassette adapter cause those worked really well.

I am not sure how much you consider as inexpensive or expensive but I use the GG-FLEXSMART-X2 from GoGroove. I picked mine up for about 40 bucks and the sound quality is great. There is everything you want an FM transmitter for your car including USB for charging, a 3.5mm headphone jack, rewind, fast forward and pause buttons, also volume control. I used to try a whole bunch of FM transmitters but sound quality and build quality this one is the best one I have used so far.

Motorola T505. Bluetooth and auto-scan for FM channels.

Different frequencies from dock compared to headphone jack?

I have the car dock, and an FM modulator (I know the FM modulator isn't the best choice, but it is all that I can use right now).
Anyway if I plug the FM modulator into the headphone jack, I get much more bass compared to plugging it into car dock.
I am running CM9 RC1, but to be honest it has done it on all of the ROMs. Is there any way to get the sound to improve from the car dock to AT LEAST equal the headphone jack???

The car dock works through usb right? If so it probably just has a crappy dac and there's nothing you can do about that. Considering the headphone dac is one of the best, I would expect the dock to sound worse.

Is there a better DAC that I can install?

Without a soldering iron, nope. The DAC (digital to analog converter) is a IC on the circuit board of the car dock. The one for the phone is on the motherboard of the phone.

I can use the headphone jack but its not a clean source.. like a line out.
I have audiophile headphones and want to connect the incredible to my fiio e17 portable dac/headphone amplifier... the best sound comes from a line out from the usb that will get amped from my dac/amp... then get sent to my headphones. Since i have my incredible sitting around.
a couple of companys make high end mp3/amplified portable players.. the Vamp from vmoda is a portable amp that allows an iphone 4 to doc in it is $600 so thats $600 plus an iphone 4.. Ibasso makes a high end android player with a awesome amp... is $800.. Hifiman makes an awesome portable mp3 player that can drive some pretty hard to drive headphones is $600..
So if i can use a clean line out audio signal from my free incredible and connect it to the line in from my pretty good Fiio dac/amp then i have a pretty darn inexpensive solution to my sensitive/subjective ears.
sorry to get too detailed.. but i am a audiophile with a severely limited budget.

Well, I did not know that. I would think the closest thing you will find is the video output cables to do this job. If memory serves, it is the standard left and right audio channels, and video. Of course you would need another cable to convert to 3.5mm jack, which is not a very clean or good looking method.
