Sennheiser's HD 450BT: active noise cancelling, Bluetooth 5.0, aptX codecs, and 30 hours of battery life.
The Sennheiser HD 450BT is a closed-back Bluetooth headphone with active noise cancellation, which Sennheiser introduced at CES in Las Vegas in January 2020. It's designed to deliver reliable sound on the go, between gigs, trains, and the studio, without ambient noise interfering.
At a glance
- Active Noise Cancelling (ANC) and Bluetooth 5.0
- Codec support for aptX, aptX Low Latency, AAC, and SBC
- Up to 30 hours of battery life according to the manufacturer
- Weight around 238 grams, dynamic transducer, over-ear circumaural design
Tech Under the Hood
The HD 450BT uses a dynamic driver in a closed, over-ear housing. It connects via Bluetooth 5.0 to up to two devices simultaneously (multipoint via HSP, HFP, AVRCP, and A2DP profiles) and supports aptX, aptX Low Latency, AAC, and SBC codecs – the low latency of aptX LL is particularly beneficial when listening to music with videos or DJing via software players, where sound and image need to stay in sync.

Classification: Successor to Two Models
According to Sennheiser, the HD 450BT succeeds the HD 4.40BT and HD 4.50BTNC models, combining features of both predecessors in one device. In parallel, Sennheiser released the HD 350BT, a version without active noise cancellation but with similar battery life. If you want to compare the technical data with a more affordable model from their own lineup, you'll find it in the article on the Sennheiser HD 400S. For DJs who are also thinking about cueing techniques at the set, it's worth taking a look at Hot Cues, Slip Mode, and Beat Jump on CDJs.
