Sony WH-CH720N vs Bowers & Wilkins Px7 S2e
The Sony WH-CH720N is the smarter buy for most people due to its impressive 35-hour battery life with ANC on compared to the Bowers & Wilkins Px7 S2e's 30 hours. In real-world use, that means you can enjoy your music longer without needing a charge, making it ideal for long commutes or travel in 2026. If luxury and sound quality are your top priorities, the Px7 S2e offers a sophisticated 24-bit DSP that elevates the listening experience. You'll appreciate the premium build quality, but keep in mind that it weighs 10.8 oz, which is significantly similar-weight than the ultra-light 6.8 oz Sony WH-CH720N, potentially affecting all-day comfort during extended use.
