The Audio Technica ATH M40X are over-ear, wired headphones known for their excellent sound quality and soundstage, making them suitable for immersive music listening and TV watching due to their low latency. However, they are not ideal for exercise and lack a built-in microphone for calls. The Razer Hammerhead True Wireless earbuds offer the convenience of wireless connectivity with a secure fit for exercise, an integrated microphone for calls, and a specialized game mode that enhances their performance for gaming. They are also more portable and feature active noise canceling, making them a better choice for travel and outdoor use. Give Feedback

"If you were to pick one headset to fill all of your needs, the ATH-M40x is a great buy with its sub-$100 price tag, pleasant sound quality, and accessories. Whether you need to use it for live monitoring, a midnight editing session, or to underscore a campus walk, the Audio-Technica ATH-M40x is a great companion."

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.”"
