Our Verdict Luxuriant and exciting, these Bluetooth headphones more than justify their price For Comfy good noise isolation insightful, clear sound Against Surround option loses focus Reviewed on 24th September 2010 These are the most luxuriant in Sennheiser's apt-X compatible range of Bluetooth offerings: bigger, comfier, with better noise-isolating. You also get its SRS surround mode; this spreads the sound but loses focus and punch. Otherwise, these cans are exciting, insightful and clear. The addition of an optional apt-X dongle improves things: treble frequencies are smoothed out, while lows are tightened, making for a more agile, musical sound. Standard control and compatibility options complete a headphone that justifies its price.
