If sound quality for music is your main interest, the 7hz Timeless offers very good sound with a special mention for its planar driver, but its lacking in features like a microphone, wireless capability, and active noise cancelling. They may not be the best choice for exercise or travel due to their poor noise isolation, non-sweatproof design, and bulkier size. The Sennheiser Accentum Plus, while more expensive, provides features like active noise cancelling, excellent microphone quality, wireless connectivity with low latency, and is suitable for a wide range of activities including calls, meetings, gaming, TV, and travel. They also offer app customization for sound and controls, and are optimized for both Android and Apple devices, making them a versatile choice if you're looking for an all-rounder with premium features.

"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."
