Sound quality decline in calls

After upgrading to 3.0 (in Italy, Vodafone) I'm experiencing a dramatic decline in sound quality during calls. While the signal icon is always full, the sound is "metal" and intermittent and my callers report very bad sound quality and difficult to understand words.
Has somebody the same experience?
Stefano

I have same issue. My new iPhone 3G S (US/ATT) sound quality on phone call is very poor. Lots of hissing noise, sometimes even it feels as though there is a small waterfall in the background. Deeply disappointed with this issue right now and in Iphone 3G s !

Sound quality of incoming calls

I've had my Blackberry for over six months, but I've always had a problem with the quality/clarity of the audio in incoming phone calls. It's very difficult to understand the person on the other end -- particularly, but not only, if the person has an accent of any sort. I want to use the Blackberry as my primary phone, but I can't "get" half of what my callers are saying to me. This does not happen on any other phone.

Hi linjane,
Welcome to the Community,
Whenever you see or feel any unusual in your device always Perform a Battery Pull Restart like this While Device is Powered On remove the Battery wait for a min. then re-insert it back wait till the device take a long Reboot.
And again the voice clearity depends on your Carier or wireless provider signal strength are you having this same sound quality problem while listening to any music files.

Poor sound quality after update on iPhone4 to iOS6

Any one with the same problem ?
After upgrading to iOS 6 on my iPhone 4, the sound quality during phone calls is very poor.
The other side is ok with listening.
The phone is not modified (unlocked and oth....)
Any advice is welcome !
Thanks !

Work in a professional studio and often use my itunes from my iphone 4gs to record sounds and samples. I have notice since the iso 6 update there is very poor quality sound coming from my phone now. It's seems the bit quality is very poor also the volume. I also noticed the songs are using way more power from the phone while playing.... Apple should really address these issues...a lot of loyal costumers, such as myself use Apple products in the music industry everyday. We have grown to expect certain standards and quality from Apple products and it seems you are taking steps backwards not forwards.

Sound quality using auxiliary cable

I have an iPhone 5 (previously had iPhone 4 with same problem). When I use an auxiliary cable to plug into my 2007 Ford Explorer the music sounds great but the calls sound awful! I have to turn the volume completely up and it's still staticky and hard to hear. The caller can hear me fine though. Has anyone else had this problem?
I am also looking into purchasing a bluetooth but I don't want to spend the money if the sound quality of the calls is still going to be awful.

After a little research (Mac help) I was able to solve (hopefully) the amp to harddrive dilema. USB to 1/4" jack cable, perhaps?
This opens up other questions such as:
1. Would I be better off just plugging the guitar straight into the harddrive, using the GBand special guitar effects, and using headphones to monitor?
2. If I use the amp's headphone slot and connect to the harddrive's mic slot from it, will I still have to use the headphones slot on the harddrive to monitor?
Thanks for any advise.

Nokia 6500 Classic Sound Quality / Buzz

Hi - I have a new 6500 Classic - great phone, but a bit concerned about the sound quality during a call - seems very tinny.
Also - when the phone is on standby - if you put the phone close to your ear you can hear a very faint buzzing from the earpiece.
Are both of these normal with the phone or would there be a fault ?
Thanks

The speakers on the 6500's are rubbish. Have got 5 X 6500 slides and 1 X 6500 classic at work. All have had both the speakers replaced, a couple twice, plus other issues.

IPhone 5s Call Sound Quality

Hey- I have a brand new iPhone 5s with AT&T and I've noticed that the call sound quality is worse than my old iPhone 4. The call sound is more muffled and a lot less crisp. Is this a common issue or is it just my phone? Thank you!

When I hold my iPhone 5S in my left hand to my left ear the sound is muffled. I remember Steve Jobs saying you're holding it wrong. Although this had nothing to do with the problem we're having now it got me to thinking. I looked at my hand holding the iPhone my thumb was on the left edge with my to two Center fingers on the right edge. My index finger was up close to the noise canceling mic on the back of the phone and my palm was down by the regular mic. I could see as I talked the voice could hit my palm travel up my hand to my index finger which was close to the microphone on the back.
I called my wife on the house phone using my iPhone 5S. She said that my voice was muffled. I took my index finger away from the microphone and moved it next to my two Center fingers on the right side of the phone. This moved my palm away from the microphone at the bottom. I did this while she stayed on the line. She said that now she could hear me clearly. I then moved my index finger to completely cover the back microphone. Once again she said that the sound was still good. I then moved my index finger a small amount away from the microphone and she said that my voice was muffled again.
I believe that the way I was holding my hand acted as a megaphone to the noise canceling microphone in the back. The noise canceling microphone thought my voice was noise and was suppressing it.
I work in a noisy environment, so I like the idea of the noise canceling microphone. Going to the settings and turning off the noise canceling microphone or putting a small piece of tape over the microphone is really not a good option for me.
For now I will use this new way of holding the phone until Apple can fix this issue.

Poor sound quality during calls

The sound quality during calls is very poor and quiet. I have the latest operating system and the volume is at maximum.
I am not using any headsets etc just using the handset in the normal way without any accessories.
I am on the verge of getting rid of this handset due to this issue. The sound quality is extremely poor when handset is held to the ear during phone calls. It is slightly better on speaker phone but not much.
Any help or advice would be appreciated before I decide to move to something else.
Thanks

Xchanvonx, thanks for the details. It does sound like your phone has a mind of it's own! Have you tried this:http://vz.to/16IVkUN and retested? Please keep us posted after you try this.

Sound quality has declined in ios8 & yosomite

Just swithched to ios8 & yosomite and I feel that the way it processes music has dramatically deteriated. Music really sounds thin and anemic no matter the genre. Older ios & operating systems--firmware?--played music bettter. Now that most of my music is in the cloud I do not use my ipod that often. Now I'm being forced to use my ipod. (i'm presently listening to my macbook and I am having the same issues. So I'm certain its the new sofware/firmware at fault. It is not the hardware.)
Any idea if Apple intends to address the sound quality issues in new updated firmware?

Hi there, I have the same issue with FaceTime an ios6. When using it with iPhone 4 and 4s, the sound quality has decreased when compared to ios5. Background white noise is now reduced but low volume sounds (such as sights and whispers) are cut out too.
This is qualitatively not an improvement, and much of the warmth of former talks using FaceTime is now gone.
I do really hope there will be an answer from apple's side soon.
Cheers

Call sound quality poor

Hi, I've a problem with all calls audio. I've tried to setting all in menu, but the quality audio during call of this phone is very poor with or without headphones.Before update of 4.4.4 the solution was disable ClearAudio+, but with this release audio is terrible without flag on CA+.I've tried another new SIM but with the same results. Call audio quality is very similar to walkie-talkie. When other people talk i ear a background disturb...

Same problem here...Except I didn't tested with disabled features.I tried three different mobile providers because I thougt this could be the problem. But when I insert the same sim card into an old feature-phone there are no problems. The problem is described by the receiver of my call. They tell me they hear my voice broken.

GD580, its sound quality and its specs

I bought the GD580, and found, to my utmost annoyance: the sound quality is way below my cheapo Panasonic micro system. You know what: I paid USD250 for the GD580 and the same for my micro system.
At one point, I thought that because the GD580 included a decoder, it would enrich my sound if I toured the sound from my system through it to the Creative speakers, using the optical cable. Plainly wrong. Bad speakers or bad amplifier, or bad decoder, or all of those reasons.
Believe me, the sound from GD580 is no way as full as the sound from my system:
- Bass is OK, until you turn up the volume, and it's not bass anymore. I would not call it music.
- Lower Medium is OK,
- Higher Medium and Treble are where my little system would give the GD580 a run for its money!!! It's no way as full as I would have expected. Poor me, wrong decision.
Creative has been well known for its speakers and amplifier, I believed, so I was looking for reasons in the decoder itself. Hey, the website lists virtually no useful info. on the decoder specs. I was wondering if it's the same quality part as used in the stand alone decoder DST-100?
My little system states: they use a 24 bit / 92kHz DAC (digital to analog converter). The Audigy 4 uses a DAC of the same specs. Does anyone know if the decoder in GD580 uses that kind of part? Or just because the GD580 uses a 6 bit / 44.kHz DAC, sound quality is inferior to an average system?
What ever the result, I must say: stay away from this GD580. Anyone has any suggestion for a better system? Further info: I use it in an environment no larger than 5 sqm.
Thanks for reading this lengthy message to its end. But I was frustrated indeed.

Hi softiam,
One thing to note on the MacBook Air, is that it has only one speaker. Unlike all the other Apple portables, there is only one speaker (located in the area of the return, shift, question mark, apostrophe keys).
With mono, versus stereo, sound the quality will sound different but it certainly shouldn't sound washed out. What are you listening to, something through iTunes?
What are you doing on the machine when the fan ramps up? How are you using the machine, is it on your lap, on a desk? What applications are you running?

6500 Slide terrible sound quality

Hello,
i just replaced my SE k810 for a Nokia 6500 slide. The problem with the K810 was battery which only lasted for one day. So i thought i`d give Nokia a try. Compared to the SonyEricsson phone, however the sound quality in Nokia is terrible. When i dial a number and press the call button the phone starts buzzing in my ear and the buzzing continues throughout the call. The sound that i hear is metallic and some of the tones seem to be missing at all.
Is this a common problem with this phone? I already returned the phone back to the service but as far as i know all they do there is updating the software, which does not fix anything. 6500 slide owners please comment on the problem.
TY

I agree, the sound quality, among other things make this the worst phone I have ever had. Nothing works on this stupid phone and no one wants to fix it because the say that it has been damaged by rain. Well, that is not strange when it is open in the top ( you charge the phone from the top, stupid feature). So I have a phone that I can't use...

Why is the sound quality on iPhone 5s videos so poor compared to iPhone4?

I used to take lots of videos with my iPhone 4 at nightclubs and or music shows and the sound quality was always very good.
Now I have just bought an iPhone 5s and the last thing I expected was that the sound on videos would be clipped and distorted badly. Does anyone have any suggestions, or is it simply that the new phone is rubbish compared to the old one (I really hope not)?

It could have to do with the noise-cancelling microphone on the device. If you are in a loud area such as the shows, it is trying to single out a sound, normally closest to the phone. I'm not exactly sure if this is the case when recording video. I just know you can turn it off in Accessibility, but that mentions phone calls. Worth a test though.

Has anyone else noticed the lack of sound quality with FaceTime in iOS 6, over wifi?

FT has lost much of its fidelity. It gates out all the noise, which I'm sure is supposed to be better, but now it's more like like a cell phone call. Sure the warmth of sound is better, but it cuts off breaths and sighs. All the things that make it so great when talking to your kids and family when traveling on the road.
If this was the cost of getting FT over 3G, it's not worth it.

Hi there, I have the same issue with FaceTime an ios6. When using it with iPhone 4 and 4s, the sound quality has decreased when compared to ios5. Background white noise is now reduced but low volume sounds (such as sights and whispers) are cut out too.

HF-300 Sound Quality - Loudness and Distortion

Hi,
Just wondering if anybody has any comparative testing on the sound quality and loudness with this unit. I am not sure if mine is faulty or just the best that can be expected from the speakerphone.
Problem is (tested using n95 8 gig and n80) that once the volume is turned up to 70% or more the units sound is distoted terribly. Sounds like the speaker is vibrating and crackling. The symptom is like when you turn up the volume on any speaker beyond its capability which then gets that distortion/vibration effect.
That said when used below 70% volume its too soft to be useable for everyday driving conversations.
Golden question if you own the HF-300 also is can you put it on 100% volume and have loud and clear sound without any negative sound quality? May help if you mention what phone model you have tested youyr with also.
I really think it must be a fault as everything marketed and reviewd about these units states 'loud n clear'. Surely its meant to be used on 100% also without such distortion or why have 100% volume possible.

Sorry to ask again but is the car kit installed with an additional single Nokia speaker or is all audio played through the car audio system (original car speakers)?
Most likely in the second case is that the installer has routed the audio incorrectly.
The kit has two outputs: stereo for music and mono for calls. Mono calls can be installed to run through the single Nokia speaker but musics should be installed to run throught the car stereo 'aux in' channel, hence the question about what audio is distorted.

IPod w/Cassette Adapter-How to Optimize Sound Quality?

I have I believe a G2 iPod (15 GB), and I play it in my car using a cassette adapter. I've found that to keep the sound from degrading at above average volumes, I have to make some adjustments. One, I have to set the EQ to 'Bass Reducer'. Two, I have to make sure the volume on the iPod is at about 80%. If I go above that, the sound distorts. The lower you go below that, the more hissing you get w/ the playback. I also turn the 'Sound Check' setting on.
Any other recommendations on how to optimize the sound quality when playing it through your vehicle sound system? Also, I'm thinking about getting a G5 unit (most likely the 4 GB Nano). Anyone have any feedback on whether I can expect better sound quality, in particular in my vehicle with the setup outlined above, by upgrading to the newer unit?

Various Methods to Connect to a Car Stereo System, or Listen to Your iPod in the Vehicle
Best:
Direct connection via the dock connector or headphone jack of your iPod, to the mini-jack input (or AUX RCA input jacks) of your car stereo. Not many low/moderate-end cars have this feature yet, but it is becoming more popular. Some aftermarket auto stereo units may have this feature.
There are also some after-market, moderate to fairly expensive direct interfaces, that hook into your existing car stereo to provide a high-quality, direct connection. Most will also power/charge the iPod. Pretty slick, but can be pricey ($80-$300). If money is no object, a clean way to go. Not very portable from car to car – if at all.

Better:
Connect your iPod to a cassette adaptor and play your tunes through your car's cassette player. Some new cars no longer come with a cassette player, so it may not be an option. It will provide even better audio quality if you can run the audio feed out of the dock connector (see the SendStation link below). Can be portable between cars that have a cassette player and also be used in your home cassette system. $5 to $20 for the adaptors, with large variations in quality (even with the same model).
Good:
Attach an FM transmitter to your iPod and play the tunes through an unused FM station. Convenient, but wireless FM transmitter signals are susceptible to static and outside interference, and can vary in strength and quality depending on your location. Some noticeable degradation and distortion, depending on the quality of the transmitter, the sensitivity of your ears and the airwave congestion in your area. Highly portable between cars, and may be used in a home system. FM transmitters that need to be plugged into a DC auto jack may not work in a home environment (without some sort of adaptor). You can pay from $15 to more than $80 for some of these.....but for FM quality audio, how much is too much?
Marginal:
Attach an external speaker system to the iPod and play it in the car. Workable, but not too good - unless you spring for a $300+ Bose (or similar) system. But why? Only if your vehicle has no Stereo system, perhaps.
Brave Techno-Geek:
This site gives some directions on adapting a car stereo by yourself. Risky, but it has been successfully accomplished by a forum member. Fairly inexpensive....unless you screw it up.
Whichever you choose, power the iPod through your car’s DC power -- either from a power adapter, or as part of the combined audio adaptor. Have a method to secure the iPod to the dash/console/etc. See the reviews for all the various accessories at the iLounge
You will also get better audio output if the dock connection plug is used, rather than the headphone jack. See Sendstation for a novel adaptor called a PocketDock. Others types are also available via this site.
I have read positive and negative reviews of each method, and within methods there are great variations in performance of different manufacture's systems – and peoples’ opinions of their performance. Some cassette adaptors/FM transmitters work poorly, some better.
FWIW: I have the iTrip Mini & the Newer Technology RoadTrip!+ FM transmitters, a Belkin cassette adaptor (used both with & w/out the PocketDock) and two vehicles with the BlitzSafe direct interface. Using the same song in the same car, I found that the FM transmitters worked, but not as good as the cassette adapter via the headphone jack. Using the PocketDock on the cassette adapter resulted in a significant audio quality improvement. As expected, the Blitzsafe direct connect was exceptionally better than everything else: less tinny, a more warmer/richer sound, and close to true CD quality.
