For an immersive music experience, the 7hz Timeless stands out with a higher music score given its Planar driver type, known for detailed sound reproduction, but lacks a microphone for calls and meetings. On the other hand, the Sennheiser Momentum True Wireless 2 offers a balanced package for various uses, including calls, with better comfort, active noise cancelling for quiet environments, and an over 28-hour battery life, optimal for extended use and travel. Note that the 7hz is wired, offering zero latency ideal for gaming and watching TV, whereas the Sennheiser is wireless, providing convenience and portability at the expense of potential latency issues.

Headphonesty

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."

What HiFi? | November 2022
"They are more comfortable and nicer to use than their predecessors, battery life is better and noise-cancelling is now included as part of the package. They’re easy to live with and you could happily listen to them for hours on end without reaching for the pause button. If your budget allows, your ears will be handsomely rewarded."
