Sony Mk2 Headphones

[0.0" / 0.9 mm] Fit perfect for my Sony headphones

[0.05 lb] My Sony headphones look like new! AMAZING!!!

[20 Hours (BT)] Greeeeeeeat headphones yay thank you sony for making these

[APS-C] Nice and perfect for the full frame 5D mk2 body

[2.1 kHz] I wanted a better quality of sound and I found it in the 306p MK2 studio monitor

[4 ohms] The adapter works great with Sony MDR-ZX110AP headphones w/inline mic.

[Closed-Back] I've never spent so much money on headphones, especially as I purchased with the top of the range Sony portable DAC (NW-WM1Z), and i did so because i wanted to know for myself if the reviews are real. I'm no audiophile, but i have been blown away time and time again, literally...laugh out loud experiences are continual. I have nearly 5000 albums and i'm slowly working through them like i'm hearing them for the first time. To Sony - thank you so much for investing in the R&D and team to allow them to create such an array of products that for those of us willing to make the financial sacrifices can enjoy. I've never liked a product so much, and i'll continue to be an ardent follow of all future Sony hi-res audio equipment, this entire experience for me was unique and mind blowing and i just can't wait to go to bed every night to escape into my music. I'm obsessed with listening to anything and everything on these headphones. And every day i'm amazed...its a gift that keeps on giving. Just WOW. To the Z1R product team - thank you sooooo much, i'm so, so grateful to enjoy my music with these!!

[0.0" / 0.9 mm] I got this as a replacement for the adapter that came with my SONY MDR-7506 headphones. Fits perfectly. Buy it.

[1.3 lb] I used to wear my Sony Pro Headphones all the time... but these are so much more comfortable and easier to work with while editing in my home studio.

[Open-Back] I have now tried 4 different headphones: Sony MDR-7506, Beyer DT990, Sennheiser HD650, Shure SRH1840. My intent was to find headphones that I could mix with, sounded suitably neutral, and have a similar response to my Yamaha HS7s, and to my HiFi which I use as an audio reference (Naim 42/110, into Rogers Studio One speakers..) Here are my conclusions/comments 1. Sony 7506: great for tracking; decent response, good isolation(I have two pairs of these..) 2. Beyer DT990: too much bass plus a sibilant top end, and 'scooped' mids. I did not like the sound of these. Returned. 3. Senn HD650: better than the Beyers but still an over-emphasized bottom end. Nice for general listening through a good headphone amp, but not good for mixing. Returned. 4. Shure SRH1840: best of the bunch, and sound very similar to the HS7s in my home studio. Bass is tight and responsive, and seems faithful to the intent of the recording. Also sound pretty close to my 'reference' hi-fi system. These are keepers. I wish that they were made in the USA.. !
