Bests & Worsts Reviews from Amazon

I purchased a brand new pair of the legendary Audio-Technica ATH-M50x headphones earlier this month. After all the rave and hype I've read about the M50 over the years I decided to spend the money and give 'em a go. I've had them for about 15 days now. After having enjoyed my Sony 7506 Studio Monitor headphones for years, I was expecting the Audio-Technica monitors to be roughly similar in design. They are totally different. The M50x is a very comfortable headset to wear and the cable design is well-designed. I was quite pleased until I listened to them. I guess I'm somewhat of an audiophile and I expect music to be reproduced as closely as was intended by the mastering artist. These headphones sound like I'm listening through a bookcase. The super high range is way too punchy and the bass is uncontrolled. The mid range felt like a lot was missing. I thought maybe it was me... or maybe the headphones needed some burn-in time. Either way, I didn't care very much for the sound. Time to research what I was hearing. Upon finding the frequency response graphs (from a multitude of sources), I discovered the 4,000k HZ range is totally absent by nearly 20db. In fact, the entire plot is all over the place. What kind of studio monitors are these??? The point of monitors is hearing audio as close to flat-line as possible. All musicality is lost when listening with these and just 5 minutes fatigues my ears. What a piece of crap. Another aspect that bothers me is the fact they aren't completed isolated. There is a lot of sound leak and I can hear all sorts of things outside the headphones. For $170 I had expected a lot more. Are all those Amazon reviews really legitimate? I have a difficult time believing that so many enthusiasts love these headphones. Maybe nobody else actually uses their headphones. Not recommended.
