speaker quality, ringtone or speaker phone

i think the speaker sound quality on Touch Diamond is not good. Low volume and weakness on mid-tone and bass. do you feel the same ?

Hmmm...Well, small speakers are weak at lower pitches. Are you comparing the quality to other similar devices or to other speakers in general?

i'm compared it with my HTC Touch Elf. I use same MP3 ringtone on both devices. and e-mail alert "wav" with pushmail. When email arrive, the voice of "You've got mail" is big different in quality.
In my Touch Elf, sometimes people will thought it's real human speech.

Fair enough. That's not good then...
TBH, I think the speaker on the Touch looks like it should have a better sound quality than the speaker on the Touch Diamond too...

Then I guess I will be happy since it's bound to be better than the HTC tornado wich was my last HTC device..

what do tou think about signal strength??

Hi,
I work in a big society of telecommunications, and I'm an acoustician. I measured a lot of mobile phones, not only WM compliant. In general, the quality of mobile phone is very bad, I measure a HTC P3300, and it's not so good as a Sony Ericsson Wxxx for example.
I mean that it's so crazy that we spend a lot of money in a WM compliant phone, having a bad voice quality ! What are HTC's acousticians doing ? It's time to put good transducers in our phones !

For signal reception strength, i think it is better or equal to my HTC Touch Elf.

I don't know why, because the speaker quality in HTC Touch Elf is still up to normal people standard. So, I believe that HTC Touch Diamond, as a sucessor, should be better or equal to that in Touch Elf; but I know it's not the case now.
Maybe this is another drawback due to the thickness.

The Touch isn't that much thicker (something like 2mm), so I don't think there's any excuse for bad sound quality.

2mm is a nassive amount when you're considering the thickness of a device. But, I agree that in a year, components should have gotten smaller, and HTC should have never compromised call quality to make it thinner.

Hi,
What do you think about the Diamond touch voice quality ?
Good, bad,...
I've got a trinity, and its so bad quality voice...
Thanks for your answer !

This is very disappointing to me, I was looking forward to the Raphael. I may just have to wait and see what the Nvidia chip goes into and hope for better sound quality. Thanks, JASTECH

My Nexus One not cutting it

every few years i like to buy a high end phone just because i do a lot with my phone. Ive owned phones like the sony w900, nokia n95, iphone 3g, and my nexus one. Besides the iphone 3g which i ditched and went back to my n95 in two weeks. after nearly half a year now and with the release of froyo that doesnt fix my complaints with the phone, i find that the nexus one has been my most disappointing. It seems either google or htc cut many corners with the phone (speaker, sound recording, phone overheating, weird problems with the touchscreen).
im not a fanboy or anything, i just prefer to buy the best possible phone when i buy one, and was considering an iphone 4 until steve jobs basically gave the middle finger to all those with the antenna problem. so now im looking into getting a galaxy s when it comes out.
anyone know if the poor sound in video recordings is exclusive to the n1, or all android phones? thanks

Well the Nexus uses an inferior codec for encoding its sound in video (AMR.)
Currently people are working to enable the AAC codec for video to allow for better recording. Since Android is open source, manufacturers can install their own codecs for use with their cameras, so its possible/likely that the Galaxy S will have better video capability (they also have included the DivX codec for watching movies I believe)
The Nexus really has a terrible speaker though

haha yes i know G1 was just as bad (a lil better imo,) but the nexus one is supposed to be a superphone! it sucks coming from nokias which cost $250-300 less than the nexus

The Moto Droid came with an outstanding speaker AND a 16gb microSD card. Those are the only two complaints I have with the N1. We should bombard HTC with emails demanding that they use speakers on par with Moto's going forward.

I'm glad I never use my speaker, lol.

If sound quality is your only complaint about the Nexus One, perhaps you should switch to a SE X10.

Speaker sucks big time, Motorla Mielsotne/Droid is way more powerful speaker, even on the low end it sounds good (but doesn't create bass)...

I always thought the iphone 3GS had a good speaker system. I think it had one where a normal phone speaker is, then two on the bottom or something. Blackberry bold had a few speaker ports, too. But I still love my N1!

speaker sounds like crap

anyone else with similar issues?
the HD2 had AWESOME sound, and this phone has a ****ty speaker. this is a BIG NO NO for me as it will lead me to stray from this HD7

sound fix
go into the htc hub and download the sund enhancer app..the settings will definitely improve the sound

Even with sound enhancer it sounds like crap. I'm trying to give my hd7 back to handler.

+1. Calling it crap is ridiculous. It's just too damn quiet. The headphones that come with the HD7 are excellent though. I wish there was a way to make the speakers louder too though...

I wouldn't be suprised if the speakers are exactly the same as the ones in the hd2.
Seems for somethings they are loud and decent, and for others you can barely hear.
It would be nice if they would make the sound volume consistent across the phone.

Must agree that the phone speakers are rubbish, but i guess HTC and MS want us to use headphones with it like apple,
as you know they seem to have copied the best of both apple and android with this device

My iPhone and iPad speakers are loud enough to share a video or game with others. With the HD7 it's embarrasing sharing a video when you can barely hear it yourself and that's with the vol at max and hand cupped around the back trying to amplify the sound.

The quality is indeed crappy BUT has anyone noticed that there just a few days ago there was a Sound Enhancer update? I did it and it sounds slightly louder when it comes to notifications. I am not a fan on playing music/video through speaker and I use my Sennheiser headphones when it comes to listening. And boy turning SRS on it sounds like my legendary N91 ! And that was one of the musts for me.
But, indeed, it would have been cool to have a decent speaker.

i returned the HD7 because of the crappy speaker. gonna wait for another WP7 release with a louder speaker

Yes, poor it is.
When I put it into the pocket, I always let the camera side face outside, bcz the speaker is next to the camera, otherwise can bearly hear the incoming calls.

This is so NOT cool.
People are idiots because they expect their expensive devices to function the way they've been advertised to function?
Really?!
I don't think this is even a case of expecting everything for nothing. There are standards and these companies that want our hard-earned money need to adhere to them instead of spending millions of dollars on misleading AD campaigns; telling everyone that their devices are the best thing since sliced bread, but are too greedy to do any real QA on them because time to market is short and besides, they're really only concerned about the bottom-line.
Quality loudspeakers on a cellphone is one of the least things you should expect from a phone these days. Every smart AND dumb phone out there has a speakerphone. Its not rocket science.
For crying out loud, these jokers even designed to phone in such a way as to EMPHASIZE the speaker grilles on the top and bottom of the phone.
And yet the sound is obviously tinny and pathetic.
And by the way, downloading software tweaks to make your phone work the way its supposed to work right out of the box doesn't make you smart...it makes you the guy who paid HTC for the privilege of doing their work for them.
Congratulations!

Speakerphone on this phone is just plain embarrassing.
My g/f has the LG Optimus 7 and when is on a call on full volume and NOT on speakerphone it's actually louder than me ON speakerphone.
Now how bad is that?

HTC HD7 Camera and sound issues

Hi guys,
For those unfortunate owners of HTC HD7? Any updates on the camera and sound issues.
The camera does not focus properly on distant objects not very far though.
The sound on the speakers is weak during calls. Need a booster app.
Thanks,

Get the Sound Enhancer app in the HTC Hub. I haven't used it yet but it gets good reviews.

I'd highly recommend re-thinking your thread starting structure. You're not going to get many answers if you begin like this.
I personally believe (and you'll probably find 99% of other users who frequent the HD7 section of these forums feel the same) that there isn't a better device on the market today. So to call us "unfortunate owners" is kind of insulting.
But i'll tell you what i've told others on similar threads, i personally haven't noticed any problems with the camera and i haven't really noticed the volume not being loud enough. Perhaps it's due to personal use, or maybe you've got a dodgy device, i dunno.

nitroxn said:

Yes, I do own an HD7, and no, it's not really for just EQ settings. In fact, unless I'm mistaken, you only get EQ options when you use headphones.
It allows you to Choose Dolby or SRS for both Audio and Video. Equalizer specifically says for headphones or external speakers only. If you want to lump Dolby and SRS into that definition, fine.
All I can say, is that it makes quite a difference when playing youtube or netflix. Quite noticable.
( I use SRS )

you guys know if the htc 7 surround has a better camera? i heard the camera on this was horrid. may be getting the hd7 soon

To be honest it isn't like he isn't somewhat justified. I mean how can you mess up the speaker and camera on a phone that is nearly identical to its predacesor. My old school touch pro 2 speaker must be at least 3 times louder than this and the camera is just a joke. I put it side by side with an hd2 and it was like night and day.

Nokia is the only company that has made cell phone camera that are actually good without the software. and the touch pro two had two speakers in the back, or thats what i remember lol. it was one of the big features of it, just like the HTC surround. the HD7 has the big screen, thats the feature. HTC wont put all their quality into one phone cause then nobody would but the rest. you want good speaker - surround, you want big screen - HD7, you want awesome keyboard - HTC 7 pro, etc. they wont make a phone with a nice keyboard, perfect screen size, amoled screen, good speaker all into one. the closest they got is the incredible.

[Q] HD7s call quality

I just got my HD7s a few days ago and I have noticed that when I am talking to someone I can hear some kind of background noise. I believe it is coming from the mic on the bottom of the phone because if I blow into the mic I can hear that crackly noise from the earpiece. Anyone else have this issue? Just wanted to check before I looked into getting a replacement.
I read on a different forum that the sim card may be the culprit. Not really sure how that could affect the call quality though. Any ideas?

no I don't have that issue

Have no idea but tons have this issue as well as me.. Can you hear yourself talk when talking to someone?

When I first got my HD7S, it sounded as if there was a noise cancelation issue during my first day of calls that initially sounded like high pitched whistling / clicking. As I made more calls, the sound went away and the call quality improved drastically. Now the quality rivals my old HD2.

Ok, i knw this is off topic but is the HD7S suppose to be on when charging? Everytime i turn it off to charge as soon as i plug it up to power it turns back on. That and the fact i can hear myself when talking is what turns me off to this phone... Well i still have 25 days left to turn it in for something else.

I figured there was an issue with the noise cancellation, or something like that. How long did it take for the call quality to improve? Like how many minutes? I already returned mine and went back to my iPhone 4. Really missing my WP7 lol. Trying to convince myself to wait till after Mango to see what is being offered.
On a side note, does anyone thank HTC quality is going down? Used to have a TP2, and aside from the lame resistive touch screen and old internals I really liked the phone and its quality, especially the speakerphone.

Indeed i do.
Considering the hardware on the "latest and greatest" isnt at all up to par with what is currently available for Android devices, part of me wants to throw half my fortune into Nokia as it will not take much to make an epic WP7 and kill HTC in the market right now.
If my TP2 hadn't have died last week (R.I.P.) I would have waited for this fall.
I hope the Mango update for the HD7S fixes all these issues because I love WP7 so far and would love to keep it. However, I dont see myself getting any other phone running WP7 due to lack of HW and sheer quality. The Gallexy S II is looking very appealing (if it ever comes out this month)

I can't say that i have this problem. I did at one time have it with my Iphone 3G, and my BlackBerry 8820, but it was on and off. Since i have had my HD7 i have not experienced this.

HD7S Noise
For the first 3-4 weeks I had the HD7S at the beginning of each 2nd or 3rd call there was an extremely high pitched squeal that lasted perhaps for less than a second, but nevertheless forced you to quickly remove the phone from your ear. If the Jabra were on for handsfree in the car no noise. It has subsequently disappeared and haven't heard it for a week or two. I have not experienced the "crackling" sound nor a microphone feedback issue.

Anyone else with this issue? I have it and have boxes up my phone to return but if it "goes away" after a while then I may end up keeping it.
Seems to work fine with headphones plugged in, and the person on the other end seems to not hear the hissing, but it's really REALLY annoying.

Did you keep the phone in the end?
I had the high pitched squeeling but am thinking that it only 'goes away' because you subconsciously learn to hold the phone differently to prevent the mic feedback... I'm only on day 3 with the phone but I thought my ears were going to bleed after the first call I made on it!

I hate to revive an old thread, but I just went out and got this phone yesterday. Is there a fix for this out, or am I just to put up with it?

I would like to know if anyone ever found a fix either.

Yeah I gave up. Back to Apple! Yay for me and the iPhone 4S, too bad HTC couldn't put out a quality WP7 device in time.

I just bought my hd7s, and it has the same problem with the microphone, its so irritating that I cannot keep it.
I guess it only needs a firmware fix, not a ROM, and not a Hardware, because how did it pass QC at first place, if its a Hardware issue?
Should we talk with HTC, or AT&T about this?

I also have had the same problem with my HD7s. I experience feed back screeching in my ear on the very first phone call as the handset near my face and it stopped after I got the speaker pressed up against my ear. This would happen quite often. It also would occur many various position like when I would pin the phone against my shoulder to free my hand or when I would place the phone face down on a table to activate the speaker phone. I could also easily induce the sound by arcing my hand a bringing close to the phone. This was very disappointing as the phone is perfect for me in every other aspect.
I exchanged the phone with AT&T for the same model. With this second HD7s I could not reproduce the feedback out of the box. After several days of phone calls I could actually hear a significant improvement in call quality, as there was an absence of the hissing background noise that I would hear before. When I really put some effort into it I find can produce the feedback with my hand by practically making a tunnel from speaker to the microphone. I'm quite certain that this should not occur under any circumstances but I've been able to overlook it thus far because this phone meets my needs in every aspect.
It seems to me that the microphone in this phone is too sensitive. It's a double edged sword of sorts because my wife says the call quality on her end is noticeably better than it has been before compared to my Tilt2.
I must say though, I spent an afternoon with a Titan and that is an excellent phone. Pure call quality, great build, better camera, I had fun with Tango and the front camera, and the even larger screen is great. It just wasn't a match for me because it lacked an Otterbox Commuter case and XDA hasn't cracked it yet-I really need my homebrew apps and custom ROMs with internet sharing. If the titan gets unlocked before my thirty day buyer's remorse is up I may be switching.
Now if you are like me and the HD7s is the best phone for you I suggest that you exchange it for another to see if you have any luck. The fact that this seems to be a consistant problem with those who experience on more than one device, suggests to me that it's a design flaw. However the fact that this thread is only 2 pages long suggests to me that we are the only ones that have an uniquely contoured face that exposes the problem.
