If comfort during extended periods of use and noise isolation are top priorities for you, the Bose QuietComfort Ultra Headphones with their best-in-class comfort and excellent active noise cancelling would be better suited. They are also a superior option for TV and gaming due to their low latency and have wireless functionality, but they come at a premium price. If budget is a concern and you prefer something more affordable for casual listening and music, the KZ ZSN Pro earbuds provide good sound quality and are wired, which means they don't require charging. They lack the active noise cancelling and comfort of the Bose but are significantly less expensive. 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."

"Undoubtedly the focus and the star of the show, the ZSN Pro’s bass is big, bold and bangin’. The amount of gusto in the low end should satisfy anyone who likes a large lick of bass and even certified bassheads will probably get a kick out of this."
