iPod Photo: Poor Sound Quality - Updates

As most of us who have bought the iPod Photo already know, the sound quality IS FLAWED. The distorsion (or background crackling) of high frequency/high output sound (such as piano, high output electric guitar & some deep bass output - however the vocals seem to be fine) is there and something needs to be done about it. Some good examples of where this kind of problem occurs, from what I have found are: Radiohead (most of the OK Computer album), The Hives (the iPod Photo cannot seem to cope with their loud distorted guitar style & very high output), and Incubus (a lot of Morning View). Some people who are still using the tinny, lacklustre stock earbuds, or just don't listen to their music carefully enough, or listen niavely, may still not recognise this.

I refuse to let this issue drop, as I have spent good money on what should be, a technically flawless sound player. I do like this player though (mine is 60GB). The features are good, the photo element is excellent, the 60GB storage is unrivalled, but the main function of the player, to play music, is not good for this one issue. It is so disappointing considering Apple have obviously overlooked this issue (or simply let it slip by thinking nobody would notice), for what is otherwise an excellent piece of equipment.

I record all my music on iTunes, using the MP3 encoder. Some people think the MP3 encoder in iTunes is poor, but it is as good as most. It is all ripped at 224kbps VBR. I use Shure E2c earphones, which are also excellent, and by far the best value for money if you're looking for a warm tone & deep bass in your sound. The step up in price to the Shure E3c might be worth it if you prefer a more detailed, but possibly colder sound.

All that considered, there is absolutely no reason why the sound should be poor on my iPod Photo (when it is fine on the iPod Mini, and using Audio software on my PC), apart from there being a hardware/software glitch. There simply must be. Either that, or something in the sound has been compromised to accomodate the photo elements or colour screen.

I have sent an e-mail to Apple regarding all this, and will hopefully hear from them soon about what is going to be done to resolve this. I will keep this post updated as and when I hear news from them. I also have a case number in motion with their customer services department, and they cannot ignore this anymore.

Something must be done! Redeem yourselves, Apple!

I have the same problem with my iPod Photo 30GB. Using the Apple In-Ear Headphone some static noise is clearly hearable, but what bothers the most is the distortion in certain songs (e.g. solo piano). I tested the same songs with the same headphones on a 1st gen. iPod Mini and the sound is fine. Not only that it is free of distortion, it just sounds a lot better!

I returned the iPod Photo to Apple to have it replaced or repaired. They returned the same device back to me and commented that there is nothing wrong about it. I can't believe that. It's obviously a problem! Are they trying to get away with it? Should we all sell our Apple stock now?....

The volume control works to remove the noise by changing the effective impedance of the headphones. In my case, using a Sony MDR-EX71SL, I was able to make the majority of the noise disappear when the volume control was adjusted to add 42 ohms worth of resistance in series with the headphone jack. One one particularly "clean" piano piece, it took 100 ohms of added resistance to remove the noise.

The problem is partly documented by Bill Machrone of PCMagazine at: http://home.comcast.net./~machrone/playertest/playertest.htm Unfortunately, he didn't test the Ipod Photo, but did show the degradation in signal quality that is typical when adding a low impedence headphone load. As well, he shows distortion on the Ipod mini (older version) that was somewhat improved on the 6 Gbyte version. It would be great for someone to run this type of test on the Ipod Photo to see how bad it's output really is.

Onother possible solution outside the volume control is to get the RadioShack Headphone 3-Channel Headphone Volume Booster (Cat. No. 33-1109). This small amplifier has a 300 ohm input impedence, so the output of the Ipod photo is not loaded to distortion. Unfortunately, the op-amps in this amplifier exhibited a bit of the noise on the "clean" piano music, indicating they're having a bit of a problem driving the low impedence load.

Why hasn't Apple fixed this? The problem is likely in the output amplifier stage of the headphone amp, which I suspect has been integrated onto the main ASIC chip which is becoming more of a System-on-a-Chip (SOP). A redesign means a mask spin, which is expensive, and Apple is biding their time. Why did this creep into the headphone amplifier? Maybe as a result of trying to improve battery life by limiting the maximum current drain of the amplifier.

I have also experienced the problems mentioned in this thread.

The problem is REAL and is linked directly to my iPp. I only notice the fuzzy sound with my Sony headphones (MDR-EX71SLW) on certain ambient/piano tracks. I have tested the same mp3s on the iPp and compared it to my Zen Xtra and it sounded fine. I have also tested my brothers 3rd gen iPod with the same mp3s and his sounded OK.

Hopefully this issue isn't a hardware problem and can be resolved with a software fix, otherwise I will sell my iPp. I find it disgraceful that a $500 mp3 player could have such a problem.

I know this thread is getting long but I felt compelled to join this discussion to express my disappointment with iPod Photo.

I owned a 3rd generation iPod 30gig for over a year which I loved. Since then I decided to upgrade to iPod Photo - the first one is 1st gen Ipod Photo 40 gig and second one is 2nd gen Ipod Photo 30 gig and BOTH exhibit the audio defect as mentioned in this thread and I had to return both units back to the store. I even tested a 30 gig iPod Photo in Apple store and it also exhibit the same issue.

Here's my finding:
1. Headphones used - Stock Apple Earbuds, Shure E2C, SONY noise canceling earbuds, and SONY MDR-V6 Studio headphone
Keep in mind I connected the headphone through the HEADPHONE jack, not the line-output jack of the dock.

2. Songs: Solo piano music ripped from few of my favorite piano albums (all modern digital recording, all sound superb on my home stereo system)

3. Different file formats: 128AAC (Apple), 192AAC (Apple), 256CBR MP3 (Apple), 256VBR (LAME).

4. Result: My 3rd gen 30gig Ipod play ALL files perfectly. No audible distortion at all.

On BOTH Ipod Photo 40gig and Ipod Photo 30gig - the whisping / fuzzy sound distortion trailed each note of piano (through the headphone jack). It is agonizing to listen to piano music through Ipod Photo 30 and 40 gig.

It doesn't matter which headphone I use - ALL OF THE ABOVE HEADPHONES exhibit the distortion when connecting through the headphone jack of Ipod Photo. Let me stress that on my 3rd gen Ipod every file sounds perfect with each of the headphone.

CONCLUSION
1. The sound distortion on piano music is NOT ENCODER or FILE FORMAT dependent - it happen on all bitrates, AAC or MP3, LAME or Apple encoder.

2. It happen on THREE of the Ipod Photo I tried - one 1st gen 40gig Ipod Photo and TWO 2nd gen 30 gig Ipod Photo. Granted my sample size is limited but I don't have money or time to test every Ipod Photo out there!!!
On my 3rd gen 30gig Ipod all files sounds fine through all the headphones above.

3. I do not have a high impedence headphone to try out but ALL OF MY LOW IMPEDENCE HEADPHONES - SONY, Apple, Sure E2c have the same problem with Ipod Photo.

4. Same piano music through Line-Output (Apple Ipod Dock) sound fine. Therefore the audio distortion is most likely a problem with the HEAPHONE JACK/HEADPHONE PREAMP, as other people have pointed out.

5. Interestingly, the distortion is MUCH LESS noticeble on other type of music. I tried very hard and on MAJORITY of Rock/Pop music I have trouble hearing the distortion! This could explain why majority of people do not notice the distortion. Especially if they never own another Ipod before. Coming from 3rd gen Ipod there is no mistake that the piano sound is distorted on the three Ipod Photo I tried.

4. I have high expection with Apple and Ipod Photo and I have say that I am extremely disappointed. Rather than waiting for fix I returned both the Ipod Photo because I did not want to go through the hassle that people went through in this thread and the problem is still not fixed.

Growing up I have owned several Macs for a long time, later switched to PC for a few years, and just recently bought a Dual-G5 Mac. I am quite happy with my G5 Mac so to find out how poorly Ipod Photo sounded compared to my old 3rd gen Ipod is a big let down.

5. Side Note: I found out that the highest quality setting on LAME VBR encoder creates files are SMALLER and BETTER SOUNDING than Apple's encoder at 256CBR. This is most noticeble on CLASSICAL music and less apparent on Rock/Pop music. I am re-encoding all my music using LAME VBR now.

Add me to the list of people who have experienced the problem. It's definitely real. The best description I can make of it to those who haven't heard it is that it sounds as if the microphone was placed just underneath a softly vibrating snare drum. It's also a little like listening to music through a kazoo.

Like others have stated, it's mostly solo piano that seems to affect the distortion. And, also like many others, I'm listening through Sony EX-71s.

May 8, 2005 3:17 PM in response to Johnny Wood

I've browsed these forums and the net looking for confirmation of the distortion problems I've experienced with my iPod Photo. I'm glad that there are others aware of the problem, I just wish Apple would acknowledge it.

I'm using the same earphones as the poster above me (Sony EX-71), with similar problems. In addition, certain songs have "hiccups" were the sound cuts out for a brief half-second or so. Playing the same MP3s on multiple computers, I have never heard this problem, or the distortion problem, with my encoded MP3s.

It's frustrating to see people discounting other's complaints about this problem.

May 8, 2005 9:06 PM in response to Johnny Wood

I am happy to report that my new iPod photo 30GB does not distort on classical piano or on heavy base notes, not as background crackling underlying the high or low notes or in the silent spaces between notes. I have listened with Sennheiser HD590's, the stock Apple ear buds and through my home stereo using both the headphone jack and the dock output as my source. I know that you are going to say that I am listening "naively," but I assure you that I am not and am very finicky when it comes to audio quality and distortion issues. I am not denying that any iPods have the issue you describe, because my friend's 40GB iPod photo does distort using the same tracks and setup on my stereo. I am just making the point that not all iPod photos seem to be affected.

When I made my iPod photo 30 purchase I was gleaming with pride of owning another quality Apple product. It's conception and design are brilliant and I looked forward to many hours of listening enjoyment. I listen to lots of jazz and classical music. While listening to jazz (Coltrane, M Davis etc..) everything sounded pretty good to me, and I was content. Then, one day I played some solo classical piano music (Ravel, Satie) which by the way was all imported using Apple Lossless, and my heart sank.. What was I hearing? It sounded like the soft passages of the piano was being played through a "fuzz tone distortion" box coming out of the right ear piece. I must clarify this problem, on my iPod seems to be only on the right side. Anyway, I first thought it was my earphones,(Shure E3's which I love) but when I tried different phones the same thing happened. I tried loading the same music on my wife's iPod mini and, NO DISTORTION! I went back to the Apple store and complained that my iPod Photo was defective, they gave me another to listen to and I heard the same distortion, then they gave me a brand new one and I heard the same thing. It wasn't until I discovered this and other threads with others complaining of the same problem that I realized I had spent my hard earned dollars on a design flawed product, and yes, I agree with others that the problem must be in the headphone amp. I'm sure Apple knows about this problem and is just hoping that the majority of iPod owners won't notice or care, but to serious music listeners Apple owes us more. I'm extremely disappointed in this product and will try to return it, does anybody have any info about Apple acknowledging this problem or when they might fix it?

I also join the others. I am experiencing the same problem on my 30GB iPod Photo. I have tried my iPod with different head phones and cassette adapters with no improvement. I have experience this problem on a lot of different songs mostly hip-hop and any other songs with a lot of bass and high guitar notes. The only way I have been able to get better sound quality is by lowering the volume on the iPod to about half when I have the head phones or cassette adapter connected to the head phone jack. If I use the docking port things get worst. I tried with a car adapter that connects to the iPod through the docking port and the cassette adapter connected to the adapter. This configuration is worst because the default volume setting through the docking port is to max volume, resulting in almost every song sounding defective. I tried with a 3rd generation 20 GB iPod with this setting at no distortion was observed. As well as other people on this forum, I just hope that Apple recognizes the problem and give us a solution.

I'm still listening to my iPod Photo 40GB with the supplied earphones. I came here looking for confirmation that I should buy Etymotic ER6i earphones and found this thread, which is very interesting and which I've read all of. I haven't been able to hear the distortion talked about on mine, (though I have a little high-frequency hearing loss) listening to a mix of pop, classical, rock and audiobooks. The only time I heard anything was when I turned on the Bass Booster on a particularly raucous rock song. I wonder if the volume cap on European models, might be having an effect? I also wonder if the quiet piano pieces we hear so much about, might be being listened to with the volume way up?

And I still don't know what to do about earphones.
