The Audio Technica ATH M40X is a more budget-friendly option with a robust build quality suitable for studio monitoring; they have a comfortable over-ear design providing good sound isolation, but their non-wireless design with no microphone limits their versatility for on-the-go use. On the other hand, the Bowers & Wilkins Pi5 S2 earbuds come at a premium price with modern conveniences like wireless connectivity, touch controls, a built-in microphone for calls, and active noise cancellation, making them better suited for those needing portability and everyday features for a wide range of environments, yet they may not offer the same sound precision for critical listening.

Major HiFi

Chris Golembeski | January 2023
"Bowers and Wilkins isn’t looking to make an obscure, premium wireless bud catered specifically towards audiophiles. Instead, it seems apparent that they’re going for the crown: a cool and popular look, an easy and comfortable fit, and an engaging stage with a great balance that is perfectly suited for mainstream listeners and audiophiles alike."
