If you're looking for high-quality sound for music, TV, and gaming, the Sennheiser HD 350BT offers excellent performance in these areas at a lower price, but they're bulkier and less portable. On the other hand, the Sennheiser Momentum Sport is more versatile for sports and travel with superior noise isolation, sweat and dust resistance, and features like heart rate monitoring, but come at a premium price. They're also better for use in noisy environments due to active noise cancelling. The HD 350BT would provide better battery life but lacks the convenient features like ear detection and wireless charging that the Momentum Sport offers. 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."

"We hadn't been expecting a new pair of dedicated sports buds but the surprise was nonetheless exciting. I got to try out the new buds at CES 2024 and while they have stayed true to delivering that "signature" Sennheiser sound, with a wide soundstage and strong sense of detail, it’s the extra wearable tech inside them that stands out to me against the best workout headphones."
