If you prioritize cost and sound quality for music and are mainly using your headphones at home, the HD 350BT is a solid choice, also suitable for TV and gaming due to its lower latency. On the other hand, Momentum 4 is more expensive but offers superior comfort, better noise isolation, and a versatile connectivity with wired option, making them ideal for travel and long listening sessions. Both are over-ear, closed-back headphones with high build quality, but the Momentum 4 has additional features like active noise cancelling and a significantly longer battery life. Give Feedback

"Sennheiser nails just nearly everything about the Sennheiser HD 350BT headphones. Sound quality is excellent, and the high-quality Bluetooth codec support is a rarity at this price point. If you don’t care for high-tech features like automatic ear detection, you’ll be delighted with these portable headphones."

"If you're looking for a slightly more affordable set of ANC headphones in comparison to the Bose or Sony offerings: the Sennheiser MOMENTUM 4 Wireless is not a bad way to go. While its ANC is technically behind the other top-tier headphones, its sound quality is ahead of the pack—as is its battery life. Not bad for $350 USD."
