I have one of these , I bought them in December / 2014 and they are very good , at the same time I bought the Beyerdynamic DT1350 that are for me a step up, only fail in the comfort , the ATH M:)50x , are better.:)

Hi Pedro, I have, ATH-M50x they all do these clicks is normal. They are excellent headphones. First they have to be used for 24 to 36 hours and only after that can make a comparison with other headphones.:D

Hi, i think the same way, i have the 80's and i like a lot, but when I'm ready then jump immediately to 325 or above. :)

Yes , I had read , I did some tests with an iPod Nano 1GB (few songs) .. and the static disappeared. But my iphone has a lot of songs and then I still connect the E17 to iphone. I have not tested the E17K not know if has the same problem . the E11 dont have the problem because I tested it.

Hi is like yours( i think) And work fine, although occasionally hear static "crackling"

Sorry, if you put on hold position the display is off!!! See if there are a problem with a switch.

  I have these two. The sound of the DT-1350 is warmer and has more depth and is more detailed. Apart from that everything has the advantage of being more portable.

Yes, my Asus DX do that if i want.

and the E17 to, the noise"crackling" it's because when sandwiched to a phone...

Hi, i have the E17 (Amp/Dac) and the E12, and both work very well with on ear ATH AudioTechnica M50XBL and the Beyerdynamic DT1350, the only experience I have with in-ear are with the old Aiwa HP V99 and the sound becomes much more clear and detailed, i love it.

hi, I bought on Amazon Uk (£ 89 I think), and has bought some Russian valves to try. I am delighted.

I have one HP-V99 Digital Monitor, i bought it in the 90s are fabulous, remain valid regardless of age.

Now cost 136.83 GBP (Inta Audio) cheap for the quality of them I am very happy with them.

Hello, I have ATH-M50XBL and I am very pleased with them. The Sound has an extraordinary crop. Low are very good, the mids and highs do not compromise, are clear. I connect them to an Amp headphones Little Dot Hybrid Valves. Try listening to Tubular Bells  - Mike Oldfield, Phenomenal !!!

It helped me a lot to take some questions I had about some of them. Surely they are missing some newer , but surely I will choose between Sennheiser HD25-1 II or Audio-Technica ATH-M50(discontinued by manufacturer) but there is ATH-M50X.
