If price is a major concern and you primarily need earbuds for listening to music with very good sound quality, the 7hz Timeless would be a more budget-friendly choice. However, they lack wireless connectivity and active noise cancelling, and are not suited for exercise due to the absence of sweatproof certification. On the other hand, the Master & Dynamic MW75-Neuro headphones offer a high-end experience with features like very good active noise cancelling, wireless connectivity with aptX Adaptive codec for low latency, making them excellent for TV and gaming, as well as an integrated AI technology for focus tracking. They also have a significantly better microphone quality for calls and meetings and are optimized for both Android and Apple devices. If you're looking for versatility and advanced features in various settings including air travel, and the price is less of a concern, the MW75-Neuro would be the superior 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."
