MWC: Sennheiser MM 450-X and 550-X wireless headphones add aptX Bluetooth

Sennheiser MM 550-X

Sennheiser has added aptX Bluetooth capability to its flagship wireless range with the launch of the new MM 450-X and MM 550-X headphones.

The aptX audio codec allows for higher quality wireless music streaming compared to standard Bluetooth thanks to better compression.

Both the MM 450-X and MM 550-X feature Sennheiser's NoiseGard 2.0 active noise-cancelling technology, plus TalkThrough for one-touch activation of the external microphone.

Also on board is SRS WOW HD sound processing technology. The bluetooth headphones can also be folded-up for added portability.

There are also MM 400-X and MM 500-X Bluetooth headphones, which also offer aptX Bluetooth playback but don't have active noise-cancelling technology.

The Sennheiser MM 450-X and MM 550-X are due out worldwide from March.
