1) Service from Headphone Zone was very good. Delivery was very prompt. Thanks to Raghav and the team.
2) Sound quality of the headphones is excellent. The bass is fantastic with mid and high frequencies to match. I am 71 years old so I cannot hear the very high frequencies. I use the ASUS U7 USB Sound Card with my laptop. This sound card has a very good DAC and built-in headphone amplifier. It was very satisfying to hear my favourite music on these headphones.
3) Comfort level was good but not great like the open type Sennheiser HD 518 which I own. A break of 10 – 15 minutes is required after 2 hours of use. But this is the price you pay for closed back headphones giving good isolation and a fantastic bass response. Hence overall no complaint.
4) 3 types of connecting cords are given by Audio Technica which is a very good idea as you have the proper cord for every type of use. I wish other companies should follow this idea.

First of all these are the great pair of cans one can buy at this price point. I have been using these headphones since 14 days. Initially i had some doubts about the product and contacted headphone zone support and cleared my queries. Their service is excellent.

I am going to clear some points for the users who are buying this:
Firstly don't worry if the box is not seal packed. Its just the "Audio-Technica way".
Second about the warranty. You will not get warranty card inside the box. Headphone Zone got you covered for the warranty.

Now coming to the headphones:
They have a very tight clamping force infact when i first wore i was like wth. To reduce the clamping force i stretch and place these headphones on a 30 cm box overnight. Due the this the clamping force got vastly reduced and now its comfortable to wear. You should do stretching minimum for 5 nights to realize the effect.

The pads of the headphones are ok. They lack the dept and doesn't go around your ears fully. Also your ears will get sweaty. I have to keep them taking off every 30 min. This is partially due to high clamping force of the headphones, so another reason to stretch your headphones. Passive noise cancellation is good in these headphones. The pads offer great seal for noise cancelling.

Cables are of good quality and looks quite durable. I am using 1.5 mm straight cable. Its much convenient for both laptop and mobile. The twist to lock mechanism is good but this is proprietary mechanism. You have to buy this proprietary cable only if yours get damaged. So ya.

Now coming to the sound:
Previously i was owning sennheiser hd 448. Since 7 yrs i had them. The sound of audio techinica in short: exceptional clear, high Highs, decent lows with great upper lows and ok mids.
The highs in this can be piercing so i equalize it with amplifier (Fiio A3). I boosted lows & mids, due to this highs are less piercing.

Overall i am satisfied with m50x. Best all-rounder at this price. R...

One of the most famous and easily recognizable phones out there, the Audio-Technica ATH M50x are a great pair of headphones for their price point. While some might argue that they are overhyped and the M40x offer a better audiophillic experience with lesser harshness, the M50x in my opinion are a very fun pair of cans with an in-your-face presentation of music. The cans are definitely bassy but imo, it's not excessive enough to bleed into the mids and the slight emphasis on bass is very good for most Indian music. It could be just me but while I find it bright and sibilant (sometimes verging on harshness), I find the mids a bit recessed. Vocals don't carry the power I'd expect but I can live with it. It's a great pair of starting cans to get a feel for Hi-Fi music but it's not the best -- certain open cans at this price range like the HD 598 are better but if you need your cans to be portable, the M50x wins hands down. It's a very well built with sturdy plastic and it definitely feels ( and looks! ) premium. If this is going to be your first pair of decent headphones, I'm sure you'll go 'Wow!". Can highly recommend especially when you'll listen to music somewhere else than your desktop.

Sonic aspects - Authoritative bass, slams and impacts, plushness, full-bodied dynamics, clarity are some of the perfections on this headphone

Downside - average instrument separation, average sound-stage, grainy treble are some of the blemishes.

I don't care what people says , I have Ath m50x . I love my headphone ..

Hands down these are the best studio monitoring headphones that i have ever came across superbly balanced between highs mids and lows
Mind you not too bass oriented headphone
But definitely the best in the price range!
