If you prioritize noise cancellation for air travel and want an on-ear form with the option to use a cable, the JBL Live 670NC might suit you, but be aware that they're not great for gaming or TV due to poor sound quality in those areas. On the other hand, if you're looking for earbuds that excel in gaming with very good sound quality and low latency, especially if you're gaming on a mobile device, the Razer Hammerhead True Wireless is better. However, the Razor lacks active noise cancelling, so it might not be ideal for noisy environments. Keep in mind the Razers are optimized for both Android and Apple, and are more portable due to their smaller size. Give Feedback

The Verge
Chris Welch | August 2019
"This latest set is more “Pro” than not in both looks and features: they offer active noise cancellation, a low-latency gaming mode, and have switched to a in-ear design with silicone tips. Just like many of the company’s laptops and gaming accessories, the 2021 Hammerhead True Wireless include Razer’s full Chroma RGB system. It makes for what Razer calls “the ultimate wireless earbud flex.”"
