Does everything – except compromise

Music should be felt and not ‘just’ heard. NoiseGard™ active noise cancellation developed by Sennheiser provides such an experience. It cancels out annoying background noise, guaranteeing rich bass and optimal sound quality. Furthermore, reliable NFC permits quick and easy connection to all compatible devices. Incidentally, calls can also be taken at any time if necessary.

Does everything – except compromise

Music non-stop

The HD 4.50R not only features stylish looks with red highlights, but also provides up to 25 hours of listening pleasure on a single charge. Modern, lightweight design and optimal comfort are therefore a must. And if it does have to be taken off, the HD 4.50R can be easily folded together and stored in its case. Sounds good, huh?
