Beyerdynamic T51i T51I Fascicule

The T 51 i opens up new sound dimensions with its excellent bass
and treble reproduction and superior materials. 
The new Tesla technology developed by beyerdynamic is now
also used in headphones for mobile applications. Whether on
your way to work, college or travelling by train or aircraft, the
supraaural T 51 i attenuates ambient noise with its closed design. 
The efficient Tesla drivers provide extraordinarily precise and
detailed sound. 
The T 51 i especially connects to Apple devices such as iPod,
iPhone or iPad. With the 3-button remote control you can control
the media playback of your player as well as phone calls. (Volume
up and down is only available with Apple devices.)
To connect the T 51 i to devices with pinouts incompatible to the
Apple standard, the delivery includes an adapter cable.
