If noise cancellation is important to you and you're often on the go, the Bose QuietComfort Earbuds II are a strong choice due to their closed design and active noise-canceling features. However, if sound quality, particularly for critical listening, is your priority and you mainly listen to audio in quiet environments, the Sennheiser HD600 headphones, with their open back design, will offer a more natural and expansive soundstage, at the cost of being less portable and leaking more sound; they also benefit greatly from the use of a dedicated amplifier for optimal performance. Keep in mind, the Sennheisers lack the convenience features such as a microphone or wireless functionality, making them less suited for calls or use without an audio cable. Give Feedback

What HiFi?
What HiFi? | September 2023
"Bose’s flagship wireless earbuds were never going to be cheap, but the question was whether they’d be competitive in an area of the market where rivals have never been more capable. The fact that the company has not only managed to implement a successful redesign, but also push the envelope for noise-cancelling and sound quality in such a highly competitive category simultaneously is truly impressive."
