If audio fidelity for music is your primary concern, the 7hz Timeless might be the better choice as they offer a higher quality sound specifically for music. However, they are wired earbuds, which can be inconvenient if you prefer the freedom of wireless use. Also, they do not come with a microphone, making them unsuitable for calls and online meetings. On the other hand, the Sennheiser Momentum True Wireless 3 offers a good balance for various use cases including calls, music, gaming, and watching TV or videos. They also have features such as Active Noise Cancelling, app customization, sweatproof design, and a detection feature that pauses the audio when you take the earbuds out. They provide a wireless experience with longer battery life and the convenience of an integrated microphone. If versatility and convenience are more important to you, and you frequently engage in calls or move around a lot, the Sennheiser would be a more appropriate choice. 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."
