Does the HD 450SE have active noise cancellation?

Yes. It has active noise cancellation tuned for steady low-frequency noise like engines and fans. It is less effective against voices and higher-pitched sounds.

Can it connect to two devices at once?

Yes. Bluetooth 5.0 multipoint lets it stay connected to two devices, such as a phone and a laptop, and switch between them.

How long does the battery last?

Sennheiser rates the built-in 600 mAh battery for roughly 30 hours of playback, less with noise cancelling on. A full charge takes about 2 hours over USB.

Does it support aptX?

Yes. It supports aptX and AAC in addition to SBC, so compatible Android phones and iPhones get better wireless audio quality.

Our take on the Sennheiser HD 450SE Wireless Headphone

The Sennheiser HD 450SE is a closed-back over-ear Bluetooth headphone with active noise cancellation, a built-in MEMS microphone and Bluetooth 5.0 multipoint pairing. It supports AAC and aptX for higher-quality wireless audio and is tuned for a warm, bass-forward sound. It suits commuters and remote workers who want ANC and long battery life without paying flagship prices. Against rivals like the Sony WH-CH720N and JBL Tune series, it offers multipoint and aptX but a less refined noise cancelling system and a heavier build.
