The 7hz Timeless earbuds are stemless with a closed design, offering strong audio quality, but lack noise cancellation, meaning they may not be ideal in noisy environments. In contrast, the Bose QuietComfort 45 headphones have noise cancellation and are known for comfort over long periods, which makes them more suitable for travel or work in noisy areas. If you prioritize a compact, in-ear design and can manage without noise cancellation, the 7hz Timeless could be your pick. However, if you prefer over-ear comfort and the ability to block out surrounding noise, the Bose QuietComfort 45 would be the better choice. 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."

"If you want a set of wireless over-ear headphones you can put on, deploy noise-cancelling on your commute or at your desk and largely extinguish the outside world for up to 24 hours, the Bose QC 45 has the edge over most of the competition at the price."
