Summary: the sound was really good, but i cannot still anymore for a headphone that's not comfortable and hurt my head, the headband and ear pads was not soft enough and make my ear hot and sweat, and i also don't like the heavy and unremovable cable.
Summary: First things first...I was expecting WAY better sound than this after having read over 30 reviews from all over on these phones....I would say the "warm" sound people speak of is the most prominent "feature" the M50's have.
Taking the M50's off and then putting on my Shure 440's made is seem like a curtain was lifted off of the music and can finally clearly hear the details the music has to offer.
Pros: Decent "punch" for certain music/awesome DJ set/VERY COMFY
Summary: First and foremost, I didn't buy these. Put in bogus purchase dates or it won't let me submit.
It was a really short audition, roughly 15 minutes.
And this will be an equally short review.
In fifteen minutes I found out six good/bad things about the M50
1) Boring sound signature.
2) Very clampy head band.
3) Uncomfortable ear pads.
4) They are not as revealing as some say they are.
5) Loved the coiled cable. Very thick and solid.
6) collapsible, iirc.
Excerpt: I have to say I kind of get why the ATH-M50 has become very popular - and it's that sound signature. With the treble and bass boost, it is more overtly incisive and fun to listen to. And it's judged well - not excessively overdone in the trebles like the Triport AE2 for example, and the bass...
Summary: These cans were decent, back when they were just above 100 bucks. They've inflated to 160 and that's just ridiculous. There is better in this price range. The SRH840's for example on eBay for 120~ bucks new, does everything better than these cans. The M50's have really punchy bass, and extremely stringent highs, they're very loose in the low end, and their mids are recessed. That combination makes for a fatally tiring listening experience.
Pros: Very pretty, does some new genres like indie rock well.
Cons: Fatiguing, Uncomfortable, Terrible bang for your buck
Summary: The ATH-M50 headphone is one of the finestI have ever listened to. The sound is simply amazing. My personal response when I first tried them was Wow. Especially after they burn in the Wow factor increases. I was in Headroom's main store in Bozeman Montana when I first tried these. I opened the session with some Sennheiser HD 600s with the center headphone ear cushion removed, which greatly increased sound depth.
