Our Verdict
Mark Levinson Nº 5909
Bowers & Wilkins Px8 Wireless
The Bowers & Wilkins Px8 Wireless and the Mark Levinson Nº 5909 are both ANC-equipped over-ears from luxury audio brands but they have different sound profiles and strengths. The Mark Levinson have a brighter sound that mimics the Harman target, while the B&W have a very bass-heavy sound that rolls off the highs. The Mark Levinson are a better choice for commuting and office work, with a superior ANC system and better mic noise handling performance. That said, the B&W are more comfortable and better-built.
