One Side Stopped Working

You can make two crayons at one time.  AFter about 6 crayons being made, one side stopped melting completely and the other side slowed down to a crawl.  Despite the fact that I put exactly the correct bulb inside.  Very disappointing.  Would not recommend.

These were AMAZING, but the right side went out after 3 months. Sad. I don't use them often and was shocked they stopped so soon.

After less than 5 months the left side has stopped working. There's no cuts or abrasions in the cable that connects the two ear pieces, but no sound comes out of the left anymore.

Photive shipped me a new pair of headphones that stopped working in under a month. It was the same issue - sound stopped coming out of the left earbud.

I emailed them about this issue, and now they are refusing to honor the warranty.

It was sent as a Christmas gift, but the left side does not work. My hope is that the return is easy for the one who received the gift, since we're in different states. I will revise my review if he likes it, if the return is easy enough.

The right side stopped working within two months and I haven't been using them that much. I'm really disappointed cause It really felt good but it's useless now.

One side stopped working after one month.  The horizontal charger I have for the xbox one still works fine and I have had it just as long.

Lasted less than a year - left side not working now.  I purchased in November of 2015.  It is now Sept 2016.
I hardly use them - I have them at work and occasionally use them - very disappointing in Sony.

Update October: The replaced earphones stopped working again with the same problem. It seems they have a short life span.

Update March: Was replaced

bought it for my daughter and my son both have the same problem, very disappointed , were these check to ensure that they were working before it was shipped? only one side works sometimes the both side does not work, amazon should look into this because a friend, said he had also bought one for his daughter and has the same problem.

I really enjoyed the sound on these, but then one side went dead.  I figured it was my fault and suspected that they got damaged at the gym or something.  Then the same thing happened to my second pair.  It seems to be an issue with the product itself.  Too bad.  I loved these right up to the moment they stopped working.
