It all started at the end of 2011. The Beyerdynamic T50ps came out, and we loved them. We loved them enough to give them a What Hi-Fi? Award. Then Beyerdynamic came out with the T51ps.
Once more, our response was nothing short of effusive. But we always had one minor misgiving. Although billed as the ideal headphones for portable use, they lacked an in-line microphone remote – putting them at a disadvantage for mobile phone users.
Thankfully, Beyerdynamic has fixed this issue. The T51is have a remote. The three buttons mean it is optimised for iOS, but the play/pause/call button will work on Android and Windows devices too.
The controls are pleasant to use: good click; responsive. As far as additions go, that’s about it. We’re told the T51is were based on the T51ps.
Aside from the remote unit, it looks as though the two sets of headphones are virtually identical.
And that’s no bad thing, for these are superb.
