4 reviews for Audio-Technica ATH-M40x Studio Monitor Headphones

  1. Rated 5 out of 5

    For $99 I’m not sure you can find may headphones that are more accurate and comfortable. I saw the video they put up about these and had to try them. Glad I did! I have been learning how to produce music and these have really helped me to hear things in my mix that I was missing before with my crappy headphones.

  2. Rated 4 out of 5

    Really good all around sound, though I wish the bass was a little bit heavier like in the M50x. I love the look of these headphones too. Really fair price for the quality you get.

  3. Rated 5 out of 5

    I really like these headphones they are perfect for mixing! they have a great analytical sound to them!

  4. Rated 5 out of 5

    3 days of use, and the truth is that his sound is perfect, so much in electronic music, rap, hip-hop, rock and metal, they have a very good comfort that to a little time forgets you that you have them in the head, his sound has a beautiful quality, they will make you enjoy the music in every sense, these have few ones bass, but if this does not matter for you too much you will be charmed with them, if you like the Bass ones he chooses them M50x or uses a Bass Booster who will help very much in this respect but the sound will continue being good. The best quality of sound for only 99 dollars. Sorry For My English, I Am Mexican :v
