If you're looking for wireless convenience with active noise cancelling for travel or noisy environments, the JBL Live 670NC would be the better choice, as they also have a longer battery life and built-in controls. However, the KZ ZSN Pro earbuds offer a wired connection that’s reliable for an uninterrupted listening experience at a budget-friendly price, and they are known for excellent build quality. The JBL has an integrated mic, which is ideal for calls and virtual meetings. On the other hand, if sound quality for music is a priority and you're on a tight budget, the KZ ZSN Pro with its balanced armature driver is a strong contender, though you sacrifice mic quality and noise isolation. The JBL's over-ear design tends to be more comfortable for long periods, while the KZ's in-ear design offers better portability. The right choice depends on whether you value features like wireless connectivity and noise cancellation over sound quality and budget. Give Feedback

"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."
