Left ear bud did not produce any sounds after 4 days of moderate use. I.E Commuting on a public train, studying, and exercising with cords tuck under shirt.

Used it for working out, on the airplane and relaxation.  Had it for a month.  After unplugging from the airplane jack.  I wasn't hard on the earbud.  The right ear bud is barely audible compared to the left ear bud.  I usually buy sony products, but this one purchase at your own risk.  The bass and sound is great when it was working.

I attempted to contact seller via Amazon to work out a replacement for my pair because generally these are pretty decent ear buds for the price, sound quality is decent, BT range is pretty solid and they always connected quickly when I powered them on.  The problem is since day one I have had rattle in the left ear bud, did not seem to affect sound so I just accepted it until recently left ear bud started to cut out frequently. Only a month old and used minimally at work, still no big deal, I just got a defective one.

My problem is I attempted to deal directly with seller in order to save the hassle of returning to Amazon and packaging it all back up but received no response. It is not too much to expect an email back from a seller in 48 hours, so I am now returning to Amazon and will try another brand that appears to offer better customer service. Hopefully seller sees this review and improves.

I bought these approximately 4 months ago and with time they stop working. I only used them lightly but within the first month one of the ear buds stopped working.  It would statistic and the sound would be on and off.. now the other ear bud is doing the same.

I plugged these in Saturday morning. I heard less activity within a day. Four days later it is virtually silent.

I'll post again in a month and adjust my rating up or down based on the results.

8/28/16- Not even a month and they're back. :( They are not bothered at all by the sound anymore.

A week after use one of the two buds stopped working correctly at high volume I can still hear a little through it but that is it.  The right still works.  Still works for listening to an audiobook but I can't handle using them for music.

The right ear bud fell apart with less than 24 hours of use. They were great until it fell apart! I loved the cord and the zipper kept everything together really nice but then again the buds should not split that soon.

Bought these a month and a half ago, the sound quality is nice but i can only hear out of one bud already.

I've used them for a week and the left ear bud is already muffled and not working correctly. Womp womp.

When I first got these they worked really well. Then after a few uses I noticed the right ear get quieter and quieter until it was inaudible. So I thought "Oh, a defective pair. I'll just get a replacement". So I called amazon and got a replacement but sadly it had the exact same problem. The left ear bud works fine and sounds great. But I didn't pay for just one bud. I may have just been unlucky and gotten two defective products in a row but I doubt it.

The right ear bud malfunctioned after about three weeks of use.  It sounds like a blown speaker, as every time the bass hits the bud "rattles" like a damaged speaker.  I didn't put it through any, real wear and tear, nor did I crank it to max capacity volume-wise.  You get what you pay for.

I purchased this item,I was really exited but when I used it I noticed that one bud isn't working, I totally DO NOT recommend it unless you like wasting your money because you're going to end up buying another set of headphones

The front of the speaker has one side sticking out while the other side is normal after 5 days of used.

I have purchased these ear buds mid December adn they came in, worked perfctly...about 3 weeks into its use the sound in the right bud dramatically decreased. You eighter don't hear anything from the right or the sounds is weak. With most ear buds they last far longer before they begin to disfunction!

I loved the product when it came and the sound was great. Unfortunately, the left ear stopped working for me a few days after I received it. So disappointed :(.
