Have two pairs...one works great, the other not so much

The first pair we bought work great, and have for years! Ordered a second set for another room in the house and only one side of the headphones works :( These were packaged great, and everything seemed fine so I didn't bother to check to see if they worked before giving them to my husband for his Birthday. Unfortunately I ordered them a couple months before his Birthday and so when he opened them and found they didn't work great, it was too late to exchange them. I would recommend testing yours out before the return date expires.

Got these for running at night/early morning.  Wanted two so I could put one on my wrist (for cars in front of me) and one on my ankle (for cars/bikes behind me).  When I tried them out, one worked perfectly, the other would only light up when I was pressing on the on/off switch.  Obviously not the best option for running.  The one that works is awesome, though - I use it on the flashing setting to make sure that it draws the attention of drivers on the road.  Would be 4 or 5 stars if both had worked.

One earbud worked great, the other would not charge.  This seems like something that should have been caught before shipping.  I'm returning them and trying another brand

The first pair I had to send back, as the back wouldn't clasp properly, but the second pair works great, and looks fantastic!

only 3 stars, this is my second pair, first one had one poor performing speaker, not worth the bother returning, and nothing else close to this low price, this pair works fine.

I thoroughly like the product -- when it works.  I am now contacting the manufacturer to replace a second pair of these.  This pair I ordered in September.  I have used them 1-2 times per week since.  Last week, they simply stopped turning on.  I made sure they were fully charged.  The same exact issue occurred with my first pair of these.

Other people may have different experiences, and fortunately the company is replacing them, but at this point, I'd rather replace them with a different brand that may be more reliable.

I'm going to try my 3rd pair to see how it goes.....

Had to return the first pair. Those never worked. The replacement seems to work fine.

Bought 2. 1 works perfectly, the 2nd....not so much. But they both fit well. Luck of the draw I suspect since I previously bought one that's still working.

I am on my second pair... The first ones started cutting out like crazy after one month.... and I had used them maybe 8 times.. My second pair doesn't get much usage either, but they seem to be holding up much better.

I have two pairs of these.  At first I loved them . . . the first pair will only hold a charge for 20 or so minutes now -- I was guessing because they got wet while running in the rain . .  So I ordered a second pair.  I've had them for about two weeks.  The last time I wore them the battery was getting low, so of course, I charged them.  Now I can't get them to power on.  They are fully charged (blue light when plugged in) but holding the button down does not turn them on.  Super disappointed.  They're great when they work though!

I've bought several pairs of these. The first couple were great, but were lost or stepped on along the way. My most two recent pairs though haven't lived up to expectations. My last paid the ear piece fell apart,making them impossible to use, and eventually breaking the wire so I could only hear out of one side. The second one has something odd going on with the volume, making everything very quiet and almost unusable. I know it's not an issue with my phone as I've used other headphones without a problem. I will most likely not be buying another pair of these

This is my second pair of these headphones. I really like them because they are not too expensive, extremely comfortable, and good sound quality. I can wear these all day at work and never feel as though my ears hurt.

Unfortunately, both sets I purchased did not work out. The first set failed within three months of purchase, and the second pair failed in less than two months. On both pairs, I'd get up from my desk and when I came back an ear piece would have just stopped working. At $30, I expect these to last longer than a couple of months of gentle use in an office setting. Unfortunate, because they are great in every other aspect.

Ordered 3 pair. One was excellent, one hardly worked, and one worked when it wanted to. Wish there was more consistency in the same product

Title says it all. The one that works is great.  The other one ended up in the trash can, I purchased a replacement off Ebay (which works great). Seems it's hit or miss whether you'll get one that works or not. Considering the price, I guess you get what you pay for.

I bought two of these, one works great, the other not so great. As other reviewers have said, the one that doesn't work, the sumo guys lock up and don't go anywhere. The one that works, the sumo guys chase each other around the square platform until one knocks the other off. Very cute. With 50/50 odds, I don't know if I would recommend.
