That's what I hate about Revain. You can buy something like that and it just doesn't work. And now I'm out. What, I take my time and get it back? They started. It probably worked for about 20 minutes, then the right earphone was cut off. Then the right earpiece worked, but the left one won't turn on. I only get this benefit during my 5 minute commute to the gym and while stretching out. As soon as I started training they started shutting down and were dead within minutes. You literally can't even plan a more annoying route for product failure. This is where I am. Worked for 15 minutes, now the left earpiece won't turn on. It's not free. Money is one thing, but I really get inconvenienced. KZ makes good products and some products really suck. And I'm guessing they're in the suction category. In my experience: KZ=earbuds are pretty good. KZ Bluetooth everything = fine at best, often sucks. I'm sure there are some good feature pairs out there. But I didn't get any.
