If excellent noise isolation and comfort for long flights are your priority, the Bose Quiet Comfort Ultra Headphones are superior, but they come at a premium price. They also support AptX Adaptive codec which can improve wireless sound quality. Alternatively, the Sennheiser 450BT is much less expensive with solid overall performance and includes AptX Low Latency, which is better for gaming and watching TV due to reduced audio lag. While both models have active noise cancelling and are good for travel, the Sennheiser may not isolate noise as effectively as the Bose. If budget is a concern and you need headphones more suitable for gaming, the Sennheiser might be the better choice. Give Feedback

"The Bose QuietComfort Ultra Headphones are a credible step up from previous Bose ANC headphones, and they're built to hang tough with the competition for years into the future. No waterproofing is a bit of a letdown, but these headphones have the technical chops to make most quite happy."

"The Sennheiser HD 450BT is a very good pair of headphones for the price, noise canceling is good and sound quality is great—quite rare at this price point. Like any product, this headset isn’t without its faults."
