Returned these the next day. Noise cancelling and volume extremely poor. Could hear the microwave as well as conversations even on the highest volume. Along with this, the volume was not loud at all, in an empty, quiet house these still made me feel like I was wearing the apple earphones that came...

Sennheiser recently added to their excellent noise cancelling headphones line-up with the HD 4.50 BTNC. The wireless headphone is their mid-range offering at $200 USD ($299 AUD £169.00). Sennheiser haven't cut any corners though, and it has many of the features of more expensive [...]

Bass-focused sound that retains balance High quality for the price range Comfortable Easy to use

No hard case
