Summary: While I found the fit of the Phiaton PS 210 BTNC headphones to be problematic, a little research will tell you that I'm the exception and not the rule. The fact is that, sonically, the PS 210 BTNC stands up to many headphones of the same price that don't have noise cancelling and Bluetooth 3.0.
Pros: Overall excellent Bluetooth and wired sonic performance, Able to use even when battery is dead, Central control unit means either headphone can be used for calls, Long battery life
Cons: Unique design means might not fit all ears, Bluetooth connection inconsistent, Control unit clip weak, Only USB charging out of box
Pros: Nice “kinda-in-the-ear” fit. Long battery life. Music and phone calls both come through with impressive clarity and fidelity. Very effective active noise cancellation, great isolation in passive (wired) mode.
Cons: Clip-on remote is a cosmetic blemish and a physical encumbrance. Tiny control wheel for volume and track changes on the remote is tough to manage. Right and left ear indicators are hidden.
