I got to run with these twice and they did exactly as markered. I thought these were the coolest little things, until I noticed a skip in the left earbud the occurred occasionally when streaming. No big deal, new tech. Until I hit the month mark, now the left earbud is constantly faint. I baby these things and have been too busy at work to use them at the gym beyond the first week I had them. So I requested a replacement. As soon as I unbox, charge, and pair the new set... The problem occurs with these out of the box, but on the opposite side. I did some additional research online, including the Samsung website, and discovered this is a fairly common problem and there has been no solution presented by Samsung to fix it. For a $200 earbud product this is a poor launch. I do not recommend anyone buy these, in fact Samsung should just recall them and start over.

I've had these for about 4 months now. For the first 3-3.5 months, they were perfect. Then the left earbud volume started to drop. I have reset them multiple times now and updated the earbud's software and gear manager app and nothing has fixed it. Now, the left earbud is almost completely quiet. I use these in an office environment, so they do not get sweat upon or have to operate in extreme temperatures and have had no contact with liquid other than a little rubbing alcohol that I used to clean them with after I noticed the volume problem. I have registered this product on my Samsung account and have submitted a request for service, but have not gotten any response. It's disappointing when you pay nearly 200 dollars for a product and you still get issues like this. I gambled and lost.

Do not buy this product. The line is apparently ridden with defects. I love the concept/design, but after 2 manufacturer exchanges I gave up and returned the product to Amazon. In 3 separate pairs of earbuds, the same issue manifested. One earbud suddenly became much quieter than the other, and the overall volume decreased below an acceptable level. The only way I could temporarily fix the issue was to mess with the balance settings in my phones "accessibility" menu. Truly disappointed. For the first 48 hours or so I really loved them. But like I said, 3 separate pairs failed within about that span of time.

Worked well for first few weeks then the left one stopped producing sound. Tried reset via button on earbud and via gear app. Updated gear app. Have not dropped or damages buds. Phone recognizes connection to phone and right one still works.
