Perfectly

Good price. Detailed sound, there are low frequencies. I have been working with them for more than 10 years and there is no need to change them.

Just get the HS5s...

TLDR: Impressive low end, but I personally found the high-end fatiguing and had to switch to something different. However, I then passed these on to a friend, who didn't find them fatiguing in his studio space and has been happy with them for years. All that said, it's not the mid-2010s anymore, and (in this price range) you should just buy Yamaha HS5s or something from Kali Audio.

Ok... now the long version:

For the price, and the era, these were impressive... I picked up a pair of MR5s in 2014(?) because I was setting up a tiny studio space/desk in my then-new apartment and wanted to downsize to something fitting the size of the room, that still had reasonable low-end, that also wasn't Genelec-priced.

I tried getting along with these new monitors for a few weeks, but my ears would get fatigued and start to tighten up after only a few minutes at moderate volumes, regardless of settings... this didn't happen with my old (very old) Event PS6s or even with the giant, peculiar M-Audio EX66s I ended up using for a hot minute.

So I boxed up the Mackies and moved up to the larger, tonally-darker Focal Alpha 65s. The Alphas were such a huge relief: they had the honesty/detail I was after, and I could track with them for most of the night without physical discomfort.

HOWEVER, I then loaned these Mackies to a good friend of mine, who set them up in his tiny back-house studio, and in that odd, cozy one-room house, these things sound great... I mean, they sound nothing like I remember them sounding in my (now) old apartment, the harsh highs have died away... and the lows are even more impressive than I recall.

Some of this change in performance could be due to the speakers physically breaking-in over time, but also, the room just makes a huge difference, obviously. This isn't a treated space, mind you, and my friend isn't doing much detailed mixing on them; he just keeps the MRs cranked when he's banging out tunes on the laptop/Maschine setup in that space... and in this context, they're way beyond adequate.

So these monitors ultimately found a happy home with a happy user who has been enjoying them for years... but now, in 2020/21, if you asked me to spend close to the same $$ on 5" project studio speakers, I'm going to direct you to Yamaha HS5 all day. I haven't heard what the newer Mackie MR5 mk3 (4?) sound like, but... just get the HS5s... unless you're ready to go all-in and get something approaching $1-2k/pair.
