The Bose Quiet Comfort 45 headphones provide excellent noise isolation and are ideal for air travel due to their active noise cancelling feature. They are more comfortable and have better controls for making adjustments on the fly. However, they are more expensive. The Sennheiser HD 350BT, while less expensive, offer higher sound quality, lower latency suitable for gaming and watching TV, and longer battery life, making them a great all-around choice, especially if you don't need the active noise cancelling feature for travel or use in noisy environments. Neither is optimal for exercise due to their over-ear design. Give Feedback

"If you want a set of wireless over-ear headphones you can put on, deploy noise-cancelling on your commute or at your desk and largely extinguish the outside world for up to 24 hours, the Bose QC 45 has the edge over most of the competition at the price."

"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."
