If budget is a key concern and you primarily consume media at home, the HD 350BT offers excellent sound and build quality at a lower cost and is suitable for TV and gaming, but they are larger and not sweatproof, making them less ideal for exercise. In contrast, the Momentum True Wireless 4 earbuds are significantly pricier but provide superior noise isolation, are sweatproof, and have features like active noise cancelling and a longer battery life which make them versatile for travel, exercise, and on-the-go use; they also have low latency, making them suitable for gaming and videos.

"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."

Andy Madden | January 2024
"It’s fair to say our brief time with the Sennheiser Momentum True Wireless 4 was a generally positive one. Comfort levels seem similar to what we have experienced before and the general flavour of sound was to our liking although we need to get a pair in to test and put up against the big rivals at the money from Bose and Sony. It could be an interesting contest."
