I purchased this cable only to find out 4 days later it was defective. The cable failed to carry audio.

Sounds stopped working after about 3 weeks of use...used for about 2 hours each week...should have returned it, but waited too long :(

These things sound way better than I could have imagined. However. I haven't even had them a month and one earbud is almost completely silent. Sound is faint even at the highest volume. Did some searching through product reviews and it seems Im not the only one with this problem. Very unfortunate. Id love to recommend these based on fit and initial sound quality but not a month in and garbage.

I've had Onkyo before and have always loved them which is why I bought this.  It was perfect until just about a week ago when the sound just stops for about 3 to 4 minutes and then comes back on.  It does this every 15 minutes.  I have filled out 4 email forms to Onkyo, trying get support.  Nothing back.  I waited on hold for 97 minutes the other day and finally gave up, this after sitting on hold two other times for a shorter duration.  I click on the find a service location and it sends me to NJ (I live in FL) over 1,000 miles away.  If I could get some service from them I might love this product.  I did find they had this problem with some older models and it looks like it has resurfaced again.

Loved it until the sound suddenly stopped working ... only a few months after buying it and about three weeks of use :(  I would contact the seller about getting a replacement but I don't know how!

After 2 weeks and approximately 4 hours of use, the left channel went inoperative.  I have sent an email to Sentey requesting a replacement. We will see how they respond.

If it worked longer than a day I'd give it 5 stars for the price and sound quality. But it didn't and I returned it.

I purchased this as a Christmas gift for my wife to use on her PC while gaming. She started using these about 10 days ago, new right out of the box. Yesterday the headphones just simply stopped working under normal use. I purchased a set of these about 2 years ago for my own use and I have never had a problem with them, so maybe this particular set was just a lemon. It's still very frustrating though to take an item new out of the box and have it only work a few days.

Bought two pairs of headphones. First pair had uneven volumes in the earbuds, while the second pair lost sound in the left ear after less than one days use. Both I had to return. When it did work, the sound in the second pair was excellent, and very comfortable to wear.

I really want to give this product a higher rating, because these were one of the best earbuds i have ever owned. The sound is crisp and the bass is much better than any skullcandy ear buds I've used. I liked how you could customize the 'sound' with the caps and the tangle free cord (while not always tangle free) was nice.

Unfortunately, after using these ear buds for a whopping two days (not even two full day. Probably around 1.5, maybe even 1) the music coming from the left ear bud dropped in volume. And I was ok, well this is weird. Stopped using them for about 5 minutes and suddenly the volume was back? It's been fluctuating since then, and it gets a bit irritating.

Have had two pairs of these. On the second pair, the right ear piece stopped playing sound. It's too bad I'm a few days past being able to exchange.

Speakers worked fine when I first received them.  Very good sound.  Mounted the surround speakers on the wall.  After 2 days, the subwoofer stopped working.  After many hours tracking down the problem, I figured out that if I used a different input, or if I pushed the digital "line in" input on the subwoofer to the right and held it there, it would work.  Amazon sent a replacement set of speakers immediately, and I was to just replace the subwoofer for convenience.  When I received the replacement set, the new subwoofer would power on, but emitted no sound whatever.  I tried all of my tricks, but it remained silent.  I sent back the replacement.  Amazon says I must send back the original set as well (they are not willing to try again), so I now have to unmount everything and try to repack it in the original box.  You may know what that is like.  I am not yet out any money, but it has been terribly inconvenient.  I suspect that Harman Kardon has a design issue with these subwoofers, since I received two in a row that were bad.

After the first few days one side of the speakers stoped working very disappointing but was able to send back

Obvious loose connection at jack so buds now distort. You can "play" with the connection to hear clear sound again. Of course this happened on day 36 so now I have to pay to have them serviced under warranty.

I am disappointed with this purchase. I used the headphones barely for 3 months and they became dysfunctional.

I initially thought it might be some battery problem, so I replaced the battery. I still hear terrible noise while playing music. I can barely hear anything.

I'm still in the guarantee period, Is there anyway I can get the defective piece replaced ?
