Hello, I finally got the MSR7 and I want to share my experience with it.
I have the MSR7 since 4 days. I haven't had the chance to try them before buying, so it was a bit risky. I should say I'm very new to this and the MSR7 are my first high class headphones (previous - SoundMagic E30).
My source at this point is my laptop and a cheap Sony NWZ-B172F player, testing with playing 320kbps MP3 and FLAC.
My very first impression was that it sounds ugly, unrefined and detailed, but in a bad sense. The instruments felt like they were separated/detached from each other, but again in a bad sense. It was harsh.
However something strange begin to happen... After some listening they started to sound really good. After a few hours there was no more hesitation if I like the MSR7 or not. It was a definite YES! I have no idea if this was due to burn-in or to my brain getting used to the sound. I think it's both, with emphasis on burn-in.
Now the sound is amazing. It's spacious, very detailed and overall the quality is great. On some songs I could clearly hear the instruments coming from different places all in and around my head. Some of the instruments sound close to what it will be if they are played live in front of me - real.
I know some people say this is a bright headphone. Except the first few hours, I will definitely say it's not bright to me. I will call it balanced. However I don't have much to compare (mostly 4-5 headphones I tried in the music shops). For me it sounds very balanced with enough bass, which is very tight and clean. I'm actually surprised with how much bass the MSR7 have. From reading before buying I got the impression they lack bass.
There are some metal songs that doesn't sound as impactful as it could, but others sound great. Radiohead sounds brilliant.
As I consider buying a DAP or DAC, I had the chance to try the Sony NWZ-A15 DAP with the MSR7 and wow! They sounded even better. Very clean, tight and overall more impactful. It was a different experience.
So, in conclusion - I'm very happy with the MSR7! I think it's an amazing headphone. It is my introduction to the audiophile world and I feel hooked! Next is choosing a good DAP or DAC for them.
Big thanks to all of you that helped me make my choice by participating in this great forum. Feel free to ask for more info if it will be helpful.
