If you prioritize long battery life and great comfort for extended periods, the Sennheiser Momentum 4 would be a better choice, and it's also usually less expensive than the Bowers and Wilkins PI7. The Momentum 4 are headphones that excel with TV and video due to their fuller sound quality and lower latency and are quite effective for noise isolation which is beneficial for air travel. On the other hand, the Bowers and Wilkins PI7 earbuds are more portable, offer superior soundstage, and have integrated wireless charging, but are significantly more expensive and don't perform as well as the Momentum 4 for calls and meetings.

"The primary selling point of the Bowers & Wilkins PI7 is the charging case that can transmit audio from any analog source to the earbuds. If you have a very specific and clear need for that feature, then the Bowers & Wilkins PI7 is for you."

"If you're looking for a slightly more affordable set of ANC headphones in comparison to the Bose or Sony offerings: the Sennheiser MOMENTUM 4 Wireless is not a bad way to go. While its ANC is technically behind the other top-tier headphones, its sound quality is ahead of the pack—as is its battery life. Not bad for $350 USD."
