Received as a gift, and very pleased on unwrapping it. The product looks the business. Charged them up (red led goes off after a couple of hours & they're done). Now to switch on... "press & hold". No amount of pressing, holding or any combination of button presses works. They refuse to light up. Oh, they work with the 3.5mm jack & sound OK. Just no wireless function.
Great finish, great look, but the worst pulsating noise in the left ear. I have tried everything I could think of without taking them apart to fix it. But no such luck.
