The 1More Sonoflow headphones come at a lower midrange price and may suit those looking for quality sound on a budget, especially with their dynamic drivers and support for LDAC for enhanced audio quality, but they are bulkier, which might make them less convenient for travel. Meanwhile, the Bowers and Wilkins Pi7 S2 earbuds are priced higher, yet offer a more compact and lightweight design with stemless earbuds and advanced codecs like AptX HD and AptX Adaptive for high-fidelity sound. The Pi7 S2 also features active noise cancelling, which is great for noisy environments, and they support wireless charging for added convenience. If call quality and portability are top priorities, the Pi7 S2 could be the better option, whereas the Sonoflow might appeal to those preferring over-ear comfort and longer battery life for extended listening sessions.

"The SonoFlow is cheap and fun, without going too far into being overly warm or annoyingly grating, or sharp sounding. The ANC features are lovely with strong app integration and excellent battery life."

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."
