A high quality bang for the buck product from Audio Technica - as usual
Ive had my ATHM30X headphones for a few days now and I am very satisfied overall. As has been suggested they did benefit from a break in period. Having not bought a new set of phones in literally decades I had no idea just how they would sound. The build quality is very
good as expected with good comfort and the sound platform is as described by the Audio Technica spec. info. The sound is very good, no muddy bass, no distortion or weak areas and all sounds are heard clearly across the range - but - I believe my old age hearing may be at fault here when I say I wished for a bit more crispness on the high end, -- to be fair im 54 years old with much loud music under my belt and I suspect my upper range is much lower these days, its the same when I listen to speakers - and as the AT info states, these are tuned to be flat across the audio spectrum with a slight emphasis on the midrange, which I knew before buying. With that in mind I have to say near as I can tell - they easily meet or exceed the given specs and claims, and then some. The headphones are efficient and easily driven, they don't require a huge input to get decent volume, at least from my Harman Kardon HK3475 receiver - a bit over 1/4 on the volume gives more than enough clean volume in the headset. And the bass, while not overboosted is definitely there, as well as accurate and solid with no distortion. If youre an extreme basshead these probably aren't for you, but if your an audiophile that wants good quality full range sound representation with a somewhat enhanced midrange, accurate solid bass and this is your price range, the M30x is a top contender - hard to go wrong here, Audio Technica is a brand Ive always trusted and one of the few companies that hasn't sold out and went downhill over the years. Overall im satisfied and feel these phones are a great bang for the buck.
