The connection is very stable. Inside a 2000 square foot 2-story home, this doesn’t cut out or become static-y. Even in the yard of another 1000-2000 sq ft, it has some impressive reachability with stable connection. The sound quality is really good. Although I am not as picky with sound quality, I can still appreciate the fine musical elements that come through in a noise-reduced headphone. The cupped on-ear headphones does a really good job keeping noise out and letting all the subtle tones and sounds in music come in. However, it’s noise-reduced; not really noise-cancelling. So while I have this on with the volume on low, I’d still be able to hear outside noises.
The mic for calls are quite clear. There’s nothing to complain about in this aspect. In fact, everything about it is pretty neat. Only 3 buttons (easy to feel for), and each does pretty straight-forward commands. Pause, play, forward, backwards, volume up, volume down, power on, and power off. In addition, if you press the power button 2x, you can activate the voice control on the device that you have connected to, which is GREAT. So far, the voice control works perfectly on the iPhones. It takes the command over the mic on the headphones (I say this, because there are still some devices that even though has voice control button action, only takes in voice commands through the original device’s mic, which is confusing).
Only thing I really have any complaint over is that the lowest sound setting on this earphone is just not low enough. That’s sort of a problem for me when I need to be able to have my private music going on in my head, but still be able to monitor the outside noise around me. I love the loud on this, but the low is not as controllable as I’d like it to be.
Overall, I really like these earphones. It folds up really nicely for storing. There’s no cables and yet Bluetooth connection is incredibly stable, even at far distances, which I love love love! It feels so nice and it’s so comfortable, that I had this on one day while doing the dishes and didn’t even realize I had it on. And no one around me was even distracted by me playing my personal music. It’s great! I haven’t taken this out for a walk in the park yet though, because I am still not used to wearing headphones out in public. I’m not part of the younger crowd nor the very old generation (yet).
