Don't panic if you want wireless over-ear Sennheiser headphones but can't stomach the $400 for the Momentum Wireless -- there are more affordable options. The audio veteran just unveiled the HD 350BT and noise-cancelling HD 450BT (pictured), two Bluetooth 5.0 models that replace the earlier 4.40BT and 4.50BTNC. They both offer up to 30 hours of listening, fast charging over USB-C and a dedicated voice assistant button, but they cost roughly half as much or less. You're looking at $130 for the 350BT and $220 for its ANC-equipped counterpart.
The two can handle AAC and AptX (including its Low Latency variant), and a Smart Control app can tweak the sound to your liking for podcasts or other listening.
Sennheiser will ship the 350BT first, in mid-January, while the 450BT arrives in mid-February. We wouldn't bet on either sounding as good as the Momentum, but the lower prices make them considerably easier to justify if you're looking for reasonably good wireless audio from a recognizable brand.
