premium earbuds. If you're frequently traveling or in noisy environments, the Bowers and Wilkins Pi7 S2 offers excellent noise isolation and is suited for air travel. However, they have a shorter battery life and lack features like virtual surround or app audio controls. The Sennheiser Momentum True Wireless 4, on the other hand, provides an excellent gaming experience, longer battery life, and wireless charging, which is convenient if you dislike cables. Sennheisers are also optimized for lossless streaming, making them a better pick for audiophiles who prioritize sound fidelity over other features. Choose Sennheisers for gaming and high-quality audio, or Bowers and Wilkins for travel and noise isolation. Give Feedback

Engadget
Billy Steele | March 2023
"While the overall sound quality is great, these earbuds fall short in terms of battery life, customization and ANC performance. Bowers & Wilkins’ ability to consistently deliver pristine sound isn’t enough to make up for what the Pi7 S2 lacks, which is unfortunately quite a bit."

Andy Madden | January 2024
"It’s fair to say our brief time with the Sennheiser Momentum True Wireless 4 was a generally positive one. Comfort levels seem similar to what we have experienced before and the general flavour of sound was to our liking although we need to get a pair in to test and put up against the big rivals at the money from Bose and Sony. It could be an interesting contest."
