If noise isolation and wireless convenience are priorities, the Bose QuietComfort Earbuds II are an excellent choice, with their active noise cancelling and robust wireless features including support for AAC codec and sweatproof certification, ideal for exercise and air travel. However, the Sennheiser IE600, while more expensive and lacking wireless capability, provides superior overall sound quality, making it better suited for critical listening and enjoying high-fidelity music, although they don't offer active noise cancelling. The IE600's sound is likely to be more nuanced and detailed, but you'd be restricted by a cable and lose out on the everyday convenience features that the Bose provides, which also include app equalization and touch controls.

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."
