If superior overall sound quality and a more immersive experience while listening to music or watching TV are crucial for you, consider the Audio Technica ATH M40X; however, they do not have a microphone for calls, are not wireless, and lack active noise cancelling. On the other hand, JBL Live 670NC is versatile with good microphone quality, wireless connectivity, active noise cancelling, and an app that offers customization, but they might not match the audio fidelity of the ATH M40X for music and TV. JBL is also more suitable for travel with features like a foldable design and longer battery life, while the ATH M40X could be a better fit for a home or studio setting. Give Feedback
