The Bowers & Wilkins Pi5 S2 are well-suited for air travel and noise isolation, making them a good choice for commuters and frequent flyers. However, if call quality and the ability to customize controls via an app are important to you, then the Sennheiser Momentum True Wireless 2 might be a better fit, as they have a higher mic quality and more comprehensive app support including equalizer settings. Both offer similar levels of sound quality and are compatible with AAC codec, ensuring good performance with Apple devices. Neither have low latency mode, which may affect watching videos or gaming. If wireless charging or weight is a concern, consider that the Pi5 S2 supports wireless charging and are slightly lighter. Give Feedback

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."

What HiFi? | November 2022
"They are more comfortable and nicer to use than their predecessors, battery life is better and noise-cancelling is now included as part of the package. They’re easy to live with and you could happily listen to them for hours on end without reaching for the pause button. If your budget allows, your ears will be handsomely rewarded."
