Short answer: the Bowers & Wilkins Px8 on measured sound quality, the Sennheiser Momentum 4 Wireless on price, though neither ranks well in its class. The Bowers & Wilkins Px8 ranks #199 of 231 over-ear headphones, rated 2.6/5, at $479. The Sennheiser Momentum 4 Wireless ranks #208, rated 2.5/5, at $227.38, $251.62 cheaper. Both are rated below 3.0/5 among the 231 over-ear headphones; for better sound, the HIFIMAN Ananda Nano ranks #4 at $319.
Why pick the Bowers & Wilkins Px8: Active noise cancelling and a manufacturer rated 30 hours of battery suit travel and commuting, and it also works over a cable. It supports aptX HD Bluetooth, which the Sennheiser Momentum 4 Wireless lacks. The catch: The bass boost spills into the low mids and upper mids sit 1.7 dB under target, so vocals sound thick and recessed, for a preference score of 50.
The Sennheiser Momentum 4 Wireless is the longer-running option. Feature set is strong: active noise cancelling, Bluetooth 5.2 with SBC, AAC, aptX and aptX Adaptive, and a rated 60 hours of battery. It is rated for 60 hours of battery against 30 for the Bowers & Wilkins Px8. Watch for: That bass boost overshoots the Harman target by a clear margin and adds about 2 dB in the low mids, which can make vocals and bass guitar thick.
Buy the Bowers & Wilkins Px8 if sound quality is the priority over the price, or the Sennheiser Momentum 4 Wireless if the price is the priority over sound quality.

The Two Headphones In Full
Bowers & Wilkins Px8: $479.00 Wireless Amazon $479.00 eBay
Pros: Active noise cancelling and a manufacturer rated 30 hours of battery suit travel and commuting, and it also works over a cable. Bluetooth 5.2 with AAC, aptX HD and aptX Adaptive covers high quality streaming on both iPhone and Android. Bass about 5.8 dB above target in oratory1990’s measurement suits listeners who prefer a big, warm low end.
Cons: The bass boost spills into the low mids and upper mids sit 1.7 dB under target, so vocals sound thick and recessed, for a preference score of 50. A 5.2 dB dip near 6.5 kHz softens detail. The Bowers & Wilkins Px7 S2e rates slightly higher for less money.

Sennheiser Momentum 4 Wireless: $227.38 Wireless Amazon $227.38 eBay
Pros: Feature set is strong: active noise cancelling, Bluetooth 5.2 with SBC, AAC, aptX and aptX Adaptive, and a rated 60 hours of battery. It also plays wired and has a built-in microphone. The deep bass lift, about 9 dB in the sub-bass and 6 dB in the bass, suits listeners who like a warm, bass-heavy sound.
Cons: That bass boost overshoots the Harman target by a clear margin and adds about 2 dB in the low mids, which can make vocals and bass guitar thick. A 4.7 dB dip near 2.4 kHz followed by a 3.5 dB peak near 6.8 kHz makes the upper midrange uneven. Its preference score of 47 trails the Beats Studio3 Wireless, which is rated higher.
