If sound quality is a priority and you're willing to pay more, the 7hz Timeless earbuds generally offer superior audio fidelity due to their planar magnetic drivers, ideal for audiophiles who want to hear every detail in their music. However, Sennheiser HD 250BT headphones are a budget-friendly option with good sound quality, a robust build, and Bluetooth connectivity, making them more versatile for everyday use, including outdoor activities or commuting. They also have the convenience of being wireless, which the 7hz Timeless, being wired earbuds, lack. Consider your budget and whether wireless convenience or audiophile-grade sound is more important to your listening experience. 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."

"As a lightweight, robust audio provider with a long battery life, the Sennheiser HD 250BT offer a lot for their price: very good Bluetooth codecs, an app connection and an extremely understated design. These headphones may not be among the most comfortable, but they deliver adequate sound – without overdriving or distortion."
