If you prioritize sound quality and a more immersive listening experience, especially for music and TV, the Audio Technica ATH M40X would be a better choice, but they lack a microphone, so they aren't suitable for calls or meetings. They are wired headphones, which provide a stable connection but may restrict movement compared to wireless options. On the other hand, the Earfun Air Pro 2 earbuds, while not matching the sound quality of the Audio Technicas, offer decent overall performance with the convenience of wireless connectivity and active noise cancelling, making them more versatile for travel, exercise, and casual use. They also feature sweatproof certification and a microphone for calls. Keep in mind that the Earfun Air Pro 2 might not be the best for gaming due to latency issues. Give Feedback

Peter Susic | September 2021
"There’s a lot to like about EarFun Air Pro 2. The best thing about them is the active noise cancellation, which works almost as well as the best true wireless earbuds out there. The audio quality is funky but enjoyable. Good dynamics and a wider soundstage save its presentation. Everyone, apart from the most diehard audiophiles, should be happy with it."
