Very good earphones for bass lovers, neat volume, the sound is good but a bit dull compared to other headphones. The headset looks visually very good, only the wearing comfort for spectacle wearers is not very good in my eyes. The workmanship is very good. I opted for the Jabra REVO still gives it 5 stars, it was a close race, the decision for the REVO much because of the wireless function and the somewhat more balanced sound, the REVO is weaker in the bass a nuance, but in the heights much better the sound as I said a bit dull in comparison.
