I've owned two wired-together sets where one stopped working, and went on a quest for completely wireless.1. The audio is crisp and clear; loud enough to hear well over even icy conditions while snowboarding. Some subtle bass too.2. Pairing is instant and automatic to my phone.3. The button control system is perfect and easy to use through the ear pads with heavy gloves in my Smith helmet.4. Battery life is exceptional! After a full charge, 5 days on the mountain, chips were still rocking 30% battery life.5. Chips are sleek and easily fit my earpads. The charging case and chips themselves look rad. Yes, I busted out, rad.6. Phone calls are seamless and my voice is clear when tested.7. Last, but definitely not least, as the battery life gets low, the voice prompt letting you know the battery is low is not obnoxious. Maybe every 15 minutes. Most devices annoy you every 30 seconds it seems.These are a must and well worth every penny!
