The 7hz Timeless earbuds have a better overall sound quality and a higher music score, making them a great choice for music enthusiasts. However, the Bowers and Wilkins PI7 are superior in comfort, have a built-in microphone with better quality, and offer active noise cancellation, which is useful in noisy environments like air travel. The PI7 also has the advantage of being truly wireless with additional features such as sweat and dust resistance, making them a better option for those who prioritize ease of use and exercise compatibility. Lastly, if gaming and watching TV are common activities, the Bowers and Wilkins PI7's lower latency will provide a more synchronized audio experience. Give Feedback

"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."

"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."
