Great set of quality earphones. Strong bluetooth connection that I can just leave the phone in the gym bag while at the gym. Sound quality is great with the bass being present, but not overpowering. The battery lasts long as well with almost a 32hr run on a single charge for me. I took a phone call with these and the other end said it was clear and crisp, although I haven't tried it with a noisy background. I'd recommend these they are great value for money.
