k, got open back R70X in today. $259 from ProAudioStar - my CC rewards came to about 220 all in. I thought these were made in Taiwan, but mine just say Japan on them. Definitely were an open box, everything is in mint condition but there is a long blonde hair stuck on one of the paddles : |
Main setup is a MOTU M4 out from a laptop into a Cranborne EC2 1RU mic preamp. It has two headphone amps in it that can run simultaneously. Not the most amazing specs but it's definitely no slouch. Never had the gain above 10. DT770 250s usually at 9

Amping:
These are much, much easier to power than many have let on. I hear very little difference in amps. Even off the lowly anemic Pixel 4a I can get to a decent volume and there's still bass there. They're harder to drive than the 60ohm porta pros, and a bit easier than the DT770 250ohms which IMO are pickier than these. I can tell very little difference on the MOTU vs the Cranborne. Motu volume is about 11:30 - 12 to match the Cranborne. I didn't bother to test on the Atom at all since I could hear zero difference in these two.
Vs Grado Hemp:
The hemp is the "darker" of the Grado range, a large part of which is the flat pads they have on them which increases bass due to proximity effect. I really loved these, but they had a few caveats that had me end up selling:
- Horrible, thick, heavy, attached cable
- Clamp. With Grados, you flatten out the headband then shape it back to fit. This gets rid of any ear pinching you might get with the rougher pads until they break in. But coupled with the heavy cable this means they don't really stay on your head very well
- Still have the upper mid Grado spike, but much tamer than anything else they offer
Both have that dynamic, vibration thing going on. The Hemp more so. Nirvana MTV Unplugged sounds like you're there, listening to it from an adjacent room with the door open. Jazz is insanely good on them. If you listen to only jazz, I'd say fork out for the new Hemp with the braided cable. It's amazing. For metal, as in death, doom, black they could be hit or miss, mostly hit. However, due to fit + cable I found myself with my PortaPros on the KSC75 clips and Yaxi pads more and more as time went on. They're easier to wear all day and sit in this liminal space of being fun while also not being distracting.
Fit + Build
I immediately like the fit of the R70x. I think the previous owner had a small head b/c the metal headband was bent a little. Quick bend back and they clamp just fine. After awhile they can start to slide though. I had an old zip up headband sleeve (neoprene) for my DT770 not in use that zipped right over the wings though and that's working fine. Cable is detachable and normal size so it's already a huge win over the Hemp. I like the utilitarian style of the R70X, but I think both are just fine. Could be a bit sturdier for the price.
winner = R70x for comfort and cable
Sound Signature
Sound in a nutshell. R70X is warm neutral, with midbass hump. This really worried me. I HATE midbass. Fortunately, the bass is controlled enough to where it doesn't bloom or boom all over the mids. But it does give them a darker signature. BUT, just like the Hemp's upper mid bump, you adjust to it quickly. 30 minutes of brain burn in and I barely notice it now. There are definitely tracks where it does not flatter the mix though, just like the Hemp could. I don't think the treble is really rolled off too much. If I eq the bass down some with a shelf they're definitely there.
Honestly, a tie here. hemp's aren't neutral, but I find the midbass bump of the R70X is not exactly neutral either. But they both work for what they are
Grain?
I kept reading about "grain" on the R70x but I'm just not hearing it. The grainiest things I've owned recently were the 58X. The bass on those was unresolving and the opposite of smooth to my ears. Even doing a hugely unfair comparison of a Myrkur's Folkesange with female vocals on my Infinity 162 speakers and Presonus S6 monitors, I'm just not hearing any graininess. But I have noticed that some people on here like cans and especially IEMs that have zero dynamics to them, are just completely smooth and compressed sounding. Like someone took your track and compressed every single peak out of it because the driver is so stiff it doesn't even represent the recording anymore. Or they're flat out hearing the graininess of analog tape recordings that were copied over and over during the recording stage and they never noticed it much before. If someone could enlighten me with a sample track of graininess, please do.
Acoustic/Live/Strings
Hemp definitely has more of the dynamic, punch, vibration going on where you can feel the sound pressure off the driver in a good way. These have more than say the 6x0 from what I've heard. But the Hemp definitely wins here hands down. Although in imaging/separation the R70X wins just because of the over ear, more homogeneous sound stage. But the Grado magic definitely wins over that for jazz/acoustic/live because it sounds so good. Classical, edge to R70X just for the more even response. And I like some more pronounced bass for classical as I love low brass, french horns, timpani, etc. I wanna feel it, screw your flutes and sibilant violins. I was a low brass player if you can't tell
Metal
I listen to a lot of death, doom, black, extreme music. Practically live on Bandcamp for metal and jazz. Metal, I'd edge it out to the Hemps again here. R70X midbass is just more of a problem than the Hemp's upper mid bumps. Midbass will ruin a metal mix more than anything. R70X is still very good though, way better than anything other than the Sennheiser 660.
Classic Rock
I actually prefer the R70x here. Fleetwood Mac, Pink Floyd, Zeppelin just have a more balanced sound and vocals are cleaner.
Synth/Electronic:
R70X again, but I gotta say the Hemp is no slouch. I can hear subbass down to 45Hz on the Hemp before it really starts to drop off. R70X it's more like 40 before the cliff, but the bass is much fuller and transitions well into the low mids. Hemp low mids are just drowned out by the upper mids with this music. It's still good and fun, just not better than the R70X
Steely Dan:
This is a tough one. Gotta say the R70X for Gaucho, Hemp for Aja. Just because I find Aja a bit darker than Gaucho. Both are great. Instrument separation is just better on the R70X though, which is crucial on these albums.
Sound shootout:
Jazz: Hemp
Metal: Hemp, just barely
Classical: R70X barely
Piano: R70X just barely
Classic Rock: R70X
Synth/Electronic: R70X
Steely Dan: tie
Overall, I'm pleased with these. Comfort, imaging, and subbass are excellent and an improvement over the Hemp. They work well across everything I listen to. Maybe they lack a bit of that magic you might get from some more expensive cans, but for 200 USD for something I can wear all day, I'll take it. Will miss my Hemps though
