The sound is very good. Unacceptable as one might expect from a 13 headset. He's actually very very good. Treble, bass, even hints of centers. Many 50 headsets can not match here.
The remote control has a good microphone, volume up / down buttons with good tactile feedback and a function key with which I can send 4 different commands to my smartphone. (Short: Pause / Play, Long: Google Now, Double: Next song, Trippel: Song Back). Also works with a Windows Phone.
Everything feels very valuable, the ribbon cable tangle not, the earplugs look like brushed aluminum with concentric circles. Stylish without adding fat. There are essays in three sizes this, they should provide a secure fit for any head or ear form.
I use the headset each day, my roommate who is also bought and I would buy it again every day I should destroy it or lose. I could, I would give this product 7 star so I am satisfied.
