Reliable but not astonishing.
Sound quality is good but don't expect to be blown away. The Sennheiser app can be used to vary sound levels but this is reasonably limited, though fine for nailing basic settings of bass, middle etc. For me, the comfort levels are a little lacking due to the non-padded head strip but then I have a shaved head so would feel this more. It not uncomfortable on the ears at all, which is something I can't say about every headset I've tried. Overall, for the price, this is great - great sound, great battery life, great build quality. If you're looking for a feature heavy device, obviously this won't win any awards, but they're a more than decent standard buy.
