If you prioritize sound quality for music, the 7hz Timeless may be the better choice with their excellent reproduction, though they lack a built-in microphone for calls. On the other hand, the Bowers and Wilkins Pi7 S2 provide good sound quality with additional features such as active noise cancelling, wireless connectivity, and a microphone for calls and meetings. They are also more suitable for air travel and exercise due to better portability and being sweatproof. The Pi7 S2 is typically less expensive as well, which may make them a more cost-effective option with a broader range of features. Give Feedback

Kazi Mahbub Mutakabbir | May 2023
"7Hz picked a bold name for the Timeless and frankly, got very close to justifying their word choice. Most importantly, the Timeless are good to go in stock form, so you don’t have to worry about source-matching and such. I can recommend the 7Hz Timeless to those who do not mind a dash of brightness up top, want a taste of planar in IEM form, and want one of the most resolving pair of earphones in the $150 - $300 price range."

"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."
