You won't be one bit surprised by the following statement. The Audio Technica ATH-DSR9BT will not be everyone's cup of tea. If you're a frequent flyer, or regularly battle through the din of road noise, bus chatter and clanging tube trains, then look elsewhere.
Astonishingly good sound quality; Comfortable; Good-looking
Expensive; No 3.5mm cable option; Relatively short battery life; No active noise-cancellation
