From what I recall this weekend I prefer the Meze 109 Pro to the Clear MG. I was looking for an open back in this price range and these two are good to compare here.I just need some comparison vs to OG clear and Clear MG, vs the 109 pro, before i pull the trigger on the meze. I currently have the hd800 which I found the most resolving headphone after owning the Utopia and adx5000. But i need a fun but still good technical headphone like the meze og clear or arya.
I think the Meze 109 Pro is a little warmer. Has a little more bass. I think the Clear MG may be a little more resolving in particular upper mids to highs. I'd honestly have to test again side by side.
It's a bit of a coin toss really. At least to my ears.
Both are very excellent and I already own both Meze and Focal headphones. Closed back. I did not own open back from either camp here. Though Focal has a distinct house sound and I felt like I had enough of that, so that's another reason I went for the 109 Pro since it is different from the 99 Classics. I feel like it adds something that much different to my collection whereas the Clear may not have.
I think this is going to be 90%+ personal preference. These are definitely two fantastic headphones to compare though. I would honestly stick the Audeze MM-500 in this line up too. Each differ a little, so you'll want to choose the one that speaks to you. The 109 Pro having the added benefit of being cheaper...but if you hid all the prices from me and I listened to these blind. They are all in the same realm.
