Low sound through headphones?

The sound seems to be a lot lower through my headphones than with my previous phone (Raphael). It seems to be unaffected by ROM as it happened on stock AT&T ROM and a custom ROM as well. Anyone else notice this? It seems to be loud enough, but i do have to crank volume settings quite high where before with my Fuze I would never even make it past 30% or so.

Don't know if this helps, but I've found that the type of headphone is important. Using not-so-great earplugs I found the sound to be quite low, but using HTC or Nike earplugs or some fairly expensive headphones, the sound was great (stock ATT ROM).

That is helpful, I guess I can't really blame the hardware, it's brand new, I don't think there is an issue there. However I am using the stock HTC headphones. Maybe I need some better ones.

hmm, i would think that stock HTC phones should do the trick -- but certainly try others and see if it makes a difference before fiddling with the device

Speaker Fidelity of Desire

Guys, DO you think HTC have resolve the soft speaker that is on the Nexus One?
Hopefully, HTC improved the speaker fidelity in Desire or used a better speaker brand in Desire... Doesn't make sense that HTC used a lousy speaker for the Nexus One for an expensive phone..

Yeah i would like to have an answer for this too, as i have Touch Diamond now and the quality of the speaker is very, very poor.. This was only only thing which made me think should i buy desire or not, if the speaker is not good in desire either, i will wait till next year or buy nokia or something worse..

Hate to be the bearer of bad news guys but the speaker on the desire is crap! Real shame for such a high end phone.

I second that!....awful .....but still a great phone!

Just took a phonecall from the missy over the loudspeaker. Could barely understand her. Its not that good.

I feel that in a phonecall the earpiece is fine but if you are using it handsfree or playing music it's pretty gash.

If you don't use full volume it's allright. But at some point it's not that good anymore.
I don't care. I never use the speaker, and when the phone rings it's more than loud enough. If I want good sound quality, I will never use a phone speaker.. ever..

Very disappointed that HTC couldn't manage to get a decent speaker (unlike the iPhone). It's not a show stopper for me but it's still not good for an otherwise high-spec phone.
The sound quality (via speaker) is quite frankly atrocious, whether it's for calls or music. I'm keeping my 3GS to use as an iPod.

What bets that speaker fidelity will be one of the features apple have focused on for the new iPhone, given their iTunes market.
Absolutely love my Desire (proud owner for about 10 hours). HArdware and software very impressive. Yet to find out about the battery life.

aww man, this is disappointing, I would expect HTC could have at least improve their speakers... I have notice that most of their phones really have crap speakers, what gives!!! even my old nokia phone beats any of their lines hands down..

The speaker is half decent, battery life - crap. Other things make up for it, though.

I'm guessing the fact they are squeezing so much processing power and screen into the thing, and the battery to power it. Speaker space wasn't such a premium a few years back.

Coming from a Touch HD, the speaker is 10x better. I have had no problems hearing alerts in noisy environments. Music sounds pretty good for being a single tiny speaker. I think it's as good as iPhone speakers.

Nope.
iPhone sounds like a boombox compared to the Desire.
And it's only through a 4 mm hole.

I've compared the Desire speaker to my Samsung Omnia HD: the Desire clearly lacks bass. Although the Omnia HD speakers sound muffled in comparison.
I guess there's no perfect speaker on cell phones.

There is no way that HTC Desire speaker match the speaker on iPhone 3GS.
I have both and it’s pretty obvious that the speaker in iPhone 3GS is much better than Desire's.
Anyway, for me, that’s the only thing that iPhone 3GS is better than Desire.

It's got a headphone jack, I'm quite happy to plug my little portable Sony speakers into that. I just cycled home from work and had forgot my headphones.. so had my favourite dancehall reggae mix playing through the loudspeaker in my pocket, it sounded fine, even full blast. Agreed nothing to write home about but it aint bad.
Will post again when I can test it for handsfree.

sounds like the trebble is too high and the base is too low, thats if there is anything in there that does base lol

testing with sound on computer, when you set the equalizer to full treble, it sounds like something close to what comes out of the desire, if there was a way to play around with the equalizer settings the quality may be improved?

So, there is nothing wrong specifically with my handset? I was thinking about returning it.
When I hear calls using phone's default speaker, the sound comes okay till one volume level. If I move up, the sound distorts.
If I use speaker-phone, things are worse. After a certain level, sound crackles a lot.
For music via phone's loud speaker, the sound doesn't crackle. But as identified by many, I can hear music with no bass & lots of treble.
Is this normal for Desire?
Comparing it with my wife's N95 (which has stereo speakers) was a nightmare for me.

The Desire's Radio Interferes with Head-phones?

Hi there,
I didn't believe it at first, but the GSM / 3G radio on my Desire interferes with the headphones while I listen to music, to the degree that it is, well... unlistenable. I have to activate the Airplane Mode in order to listen to music, which I think is just preposterous. I've never had that problem with any other phone.
You know that annoying noise that cellphones can induce in stereo speakers, if the speakers are connected to an unearthed socket? That's what I hear in my headphones on the Desire.
Is this due to a unique fault in just my unit, or do any more of you hear this noise?
Cheers

I hear it only when the internet connection is active - and even then it is quite low (but still there).
So all I have to do is turn off internet connection and the problem is solved.

Hi i'm glad someone else has noticed this thought it was just me
here was my thread about it:
http://forum.xda-developers.com/showthread.php?t=683024&highlight=shielding
Definitely seems like poor shielding to me. I can't believe nobody else has noticed it. Maybe because I use sound isolating headphones so it makes background noise quieter?
A very serious flaw for something I use as my main Mp3 player

Someone at your thread wrote "Apparently I had the 'only use 2G networks' option turned on! Now with 3G the issue is gone". I am actually on the countryside at the moment and unfortunately required to connect using GSM / Edge, perhaps that's what causing the noise and it will disappear on 3G? Either way, it shouldn't be there in the first place

Just under that option is the option to turn off mobile internet...try that instead, at least you still get phone calls and messages that way.

I just replied in the other topic. I have this problem withg several in.ears, and disabling internet or enabling airplane mode doesn't help at all. As long as the phone plays sound (and for four seconds afterwards - ie, as long as the "soundcard" in the phone is turned on) it makes a hissing sound, making it completely unfit for music and to some degree tv series/movies too.
edit: Guess I should mention that the volume is also too loud, there is NO way I can have it more than two or three steps from the bottom, and between the lowest step and "silence" (ie. only hissing) there is quite a jump in dB.

What product are you using? I've only noticed this on products of poor quality. Both my AKG and MW600 have no problems with it at all.

As I said in the other thread, I'm using a good quality closed headset and there is no hint of hiss.

I have the same problem with a pair of Creative Aurvana in-ears and a pair of Sennheiser CX300. While they are not the most expensive sets you can buy, they bot sound fine while used with other devices - ie. a Nokia 5800, an iPhone 3g and my old Creatove Zen Micro. It is most certapnly the Desire that is the problem.
I expect to hear noise wih low ompedance in-ears on cheap laptops and non-branded china players, but not on somathing claiming to be a great multimedia phone at a pricetag of $620 (unbranded in Norway).
This prolem most likely stems from bad intrnal isolation of the audio chip/wires/jack, and would ofc not be heard with a BT headset... As to your AKG, unless they are low impedance in-ears, whether you hear noise in them or not is equally uninteresting.
I would really like someone with a good pair of low impedance headphones and good hearing to say that their phone is NOT producing this white noise. My pal didn't think his did, but it sure does. If it is just faulty units, it means it can be fixed, so I don't have to spend a few months getting my money back and find another phone to buy.

iI contacted HTC regarding htc desire volume

I am not happy at all abuot the sound quality its too low, so I contacted them and ther reply is:
Thank you for contacting our Customer Support Center. With regards to your inquiry, Please note that we didn’t receive any problems with HTC desire volume ,however you can search over android market for a 3rd party application to raise the device’s volume Thank you once again for your continued patronage. Best regards
anyone know any apps k and r u happy with the volume , please contact theme if your not let theme know about this issu
Thanks

You aren't very clear. Is your problem the quality or the volume? And is your phone branded or not? Branded phones are sometimes limited in volume.

i am not happy about the low handsfree rear speaker volume either. the phone ear piece speaker is ok volume wise. but the handsfree speaker is pretty crap and might probably take the crown for the worst handsfree speaker on the market. i have two desire phones and both are the same. loads of similar complaints on many forums (moneysavingexpert, avforums, three blog and others). htc must be having the heads in the sand if they havent heard about it. i think it is a deliberate denial of an obvious poor handsfree speaker, htc had some chap called dave who said he was following the posts on three blog and replied about poor stocks etc so HTC is aware about this issue, they are just dishing out denials or htc tech guys need to have their ears checked ASAP.
just put anyother phone or media player next to the htc desire and play the same sound / music via all the devices and htc desire will most probably take the crown for having the poorest rear speaker. at high volumes (which one needs anyway if one wants to hear in anywhere where the background noise is present) there is a lot of treble noise. on my archos 605 if i keep half the volume, for the same clip i wont get as good a volume on my desire at full volume. it is pretty easy to miss the notifications when out and about because one didnt hear the notifications.
the poor volume is obvious while using google navigation. while tomtom 760T has a great volume, but when i use the desires speakers for navigation voice, i have to keep the music off and can get tricky in busy traffic as sometimes the volume isnt enough or is barely enough. this might not be a problem when using car stereo with bluetooth but my car stereo does not have bluetooth or an input socket in the front as it is a few years old car.
the notifications volume must be with some internal settings i canty access as i have tried adjusting everything but it does not make a difference, or much of it. but the new yahoomail app i got from the market has a much much better volume that is easily audible. for the other notifications i downloaded the 'car mode' app that makes the notifications louder by using the rear speaker, i guess otherwise it uses the earpiece speaker by default, hence the low volume for the notifications. the volume is ok when inside and when it is quiet but just not enough when out and about. i didnt have a problem with speaker volumes with any of my handsets in the last decade, i am just adding that my ears are fine as they get checked by occupational health at work!

Thanks 4 your reply
I decided to sell My phone,Its useless as a media player
No support no update Thank You HTC

I bought 2 HTC Desire phones for me & my wife. Both of them have the most lowest & weakest speakerphones I have witnessed in any phone over the last 10 years. Even the regular flip phones which are not smartphones had the good quality speakerphones for conference. It's a shame having such a Flagship phone with pathetic speakerphone.
I called HTC customer service and though I already new their scripted answer I still asked 'Is it a known issue?'. There reply was what I expected. Complete Denial. 'No, this is the first time we are hearing it.' What a joke. I told him to do some google and check the forums. I also complimented him for lying so well.
He asked me to do soft reset, hard reset and do factory reset which would wipe out all data. Simply put they were giving me a run around & wasting my time so I stopped him right there that son I have already done that.
He transferred me to their Repair department, who turned out to be Telus customer service and they said since it's a new phone you have a 1 year warranty, take your phone to the store you bought it from with the receipt and they'll replace it. I asked what if the replaced phone also have the same problem then what are my options. She said you need to discuss it with the store from where you bought it from, they can let you have another phone but you can't break the 3 year contract.
Dealing with the phones issue is frustrating enough and on top of that frustration caused by the absolute denial by HTC's customer service & not providing a solution is totally unacceptable. I'm selling my HTC Desire on ebay and probably buy the Nokia N8.
Sometimes all what a customer needs is an apology and admission that yes we are not crazy, there is a known issuee with the phone and they'll fix it. But they are following on the footsteps of Apple who literally made their customers feel like they are crazy when they reported about iphone 4 antenna issues. Shame on Apple for telling them that they are not holding the phone properly as if dealing with ignorant kids. Such behavior isn't expected from such large and reputable corporations. Nokia on the other hand makes the best phones and admit their problems and fix them.

What do expect from a tiny rear speaker?? If you want decent sound then plug in some speakers!!
Or are you the annoying twats who play music when in public?

To be fair, I also have a T-Mobile Pulse Mini as a backup phone, and the internal speaker is way, way, better than the one on the Desire.
IMHO, the Desire's speak is "ok", if you want to take/make a handsfree call whilst sitting at your desk, but is worse than useless if you are in a car - for both taking calls and satellite navigation. I do have bluetooth handsfree, so it is less of an issue for me personally, but given the price of the phone I think they could've made the internal speaker a little higher quality.
Regards,
Dave

But the phone isn't a media player in the traditional sense, you wouldn't watch a film on it without headphones...given, it could be a bit louder for the navigation side of things but I've got Sat Nav for that...

The headphone volume is really low on my desire (stock t-mobile rom) even with hi end noise cancelling headphones and volume at max (am told this is a problem with the t-mobile rom), now I use mixzing which has a gain and graphic for music. It is almost imposible to watch a film while on the underground tho, which is really annoying me, am waiting to see if the froyo update fixes this, if not I will root and change to unbranded rom.

I don't know what's in the HOX but it pretty much sucks balls. You can even hear a *poof* when the music starts and a few seconds after it stops, not to mention the crappy sound itself.

@Gibeon - you must have a faulty phone as I don't get any of that
OP - Really is very reliant on the quality of your audio files I find, poor quality mp3's will sound TERRIBLE, worse than on some other phones. If it's high quality FLAC rips then the sound quality is really very good for a phone, better than the Desire I used to have for example and miles better than the iPod I used to have.
I have Denon in ear for going out and about with and a couple of quite high end (full size over ear) headphones and good quality files sound really good through them. The one thing I would say is that the output volume is not as high as some other phones I have tried, so you do need quite sensitive headphones if you like your music loud.
No idea what the DAC is but for me it's a great portable music player. No such thing as audiophile in any phone but it's definitely one of the better ones i have tried.

Really? I've heard several cases of this behavior so I guessed it a widespread problem.
GSMarena has put the real specs to the test, here they are.

I also find the OneX sound much worse than on the desire. Beats only changes it from tinny to plasticky. It is so much worse, actually (both on stock earphones and via car stereo) that I no longer enjoy listening to music from the phone in my car, the sound gets on my nerves.
Instead of shelling out gazillions for having the name of a makebelieve gangster on their stuff, htc could have bought millions of decent audio chips and still give them a catchy name That would be the htc spirit I always liked.

I've seen the GSM Arena article, and I can only talk from personal experience based on my phone not yours. I do not have the issues you mention at all. Could be a bad batch of components hence why some are better than others. I've seen plenty of people say it's great quality, plenty of people say it's crap, so would seem to point towards that logically.

This is due to the player you're using. I swear by neutron. The ui might be a bit overwhelming for non audiophiles, but I'm getting some great sound with this app and beats disabled.
After some time with this phone, I'm finding the hox's sound to be quite different, but not necessarily of lesser quality compared to my old sgs1 with voodoo.
My advice would be to just change your music app and if you don't like neutron as I proposed, you could go with power amp or player pro with dsp pack.
On a final note, make sure you get your hands on a decent pair of headphones before commenting on the quality of a Dac. You can't really make any assumptions about these kinds of things if your basing your experience on a free or a $30 pair of ear buds.

The sound is not the best in the world but its much much better then Galaxy S with voodoo sound while playing at the highest volume, at highest its just awesome stable with this beatsaudio thingy tested using Sennheiser HD 555, mind you galaxy S3 has a cheaper version of op amp used in S1.
The HTC One X have the very best sound in every angle: microphone/speaker/headphones/ear speaker

The volume and quality through the headset is good, unfortunately the loudspeaker is rather poor and doesn't go very loud. Typical HTC though, their speaker components tend to be rather low quality.
LG tend to have alright speakers (The Optimus 2X went fairly loud), but I can't say whether the 4X's will be any good or not
EDIT: I realise you were specifically asking about the quality rather than the volume. The quality is pretty good, you wont be disappointed by it. The Galaxy S III supposedly has fantastic audio quality though, which is likely to be better than the One X's due to the fact that the One X uses 'Beats' (which sucks) and the SIII has a Wolfson Micro WM1811 which is apparently pretty awesome (http://www.wolfsonmicro.com/products/audio_hubs/WM1811/).

yeah right "ultra-low power" is just rubbish

It's not. I've tried a number of different music players, different EQ's, different thread priority for the audio. All exhibit the same fundamental problems arising from a poor quality DAC. Heck, even the volume up/down sound causes the pop/crackle issue.

I've tried 5 different sets of headphones on my One X, some in ear, some open back, one Bluetooth. The same problems could be heard on all of them in varying degrees.

If your guys phones are rooted, flash the latest dspequalizer on this phone. Helps tremendously with sound quality. I agree with the person talking about flac files. You don't even need to have flac, just try to get high bitrate mp3s. I listen with Beyerdynamic headphones which take more power to drive, but it's enough for me and sounds great.

I totally agree and I don't think my Grado SR60i's or Shure SE215's are to blame. Really, the quality just sucks on the HOX I own.

Of course the dac is not the best. The point I was trying to make is that I was able to eliminate most of the hissing and strange pops upon volume changes etc by switching to the neutron player leading me to be believe that these are not necessarily related to the Dac itself.

With my beats headsets i have excellent audio quality, didnt try the original one...and the sound from the speaker? Well i dont know what you expect, in my eyes it is good enough (i dont listen to music over it) ... and BTW, i use well ripped mp3s because over the beats headset you can hear every single detail in songs ... youtube is also great ...
I dont know, but probably i have a special OneX i dont have any single issue the guys so far had reported ... i am just confused now why i dont get a S-OFF device

As far as I know, the beats audio plugin is only a peace of software, isn't it? It has nothing to do with special hardware, its just an equalizer setting. But I'm confused some sites say, the one x's audio chip is the same, that is build in the one s, but the explanation of the Tegra 3 chipset says, that it is able to handle 7.1 surround sound, which means it includes an audio chip. I think I have to wait for reviews of the optimus 4x to solve this problem
