Rock-It Sounds just recently released their R-Studio and R-DJ headphones. Based on the success and excellent sound provided by the R50 earphones, I had to give both of these a try.
I'll be updating with impressions over the coming week or two. Currently burning them in.
With the limited time I've spent with the R-Studio so far, I can say it sounds excellent for the $73 it is going for. The mids and highs are neutral and engaging, and there is a lot of bass coming from these. Due to this, the whole sound signature leans toward the warm side, yet it never muddies things or dips the midrange, unlike some Dr. inspired headphones out there. Some slight EQ may work wonders here...
Surprisingly enough, the R-DJ has less bass compared to the R-Studio, which I didn't expect. Testing to see how well some massive bass boost and more power will work...
The R-Studio uses 50mm Cobalt drivers, while the R-DJ uses 40mm Neodymium.

R-Studio (25 hours burn in so far)
The R-Studio from Rock-It Sounds claims to be a "True Audiophile Product". This intrigued me, as the R50M IEM of theirs which I love has incredible sound quality. Not only does the R50 have incredible sound quality for the price, it is incredible for an IEM in general, besting many IEMs that are several times more expensive.
The R-Studio uses an Aluminum like alloy along the sides, and uses Leatherette (not real leather) on the earpads and headband. Despite not using premium materials, the headphone has a premium look and feel to it. They are quite comfortable to wear for extended periods, and I had no desire to try different earpads or a different headband. The seal from the pads was very good, and they isolated very well. There was some sound leakage that others could hear, but not much. The standard removable cable isn't anything special, but it is a nice feature that I enjoy, and makes experimenting with higher quality cables a breeze.
With a name like R-Studio, you would expect a neutral, unforgiving Studio Monitor type sound. That isn't the case here. Rock-It describes these as having an overall "warmer" tone, to which I agree. Sub bass and mid bass are bumped up a bit, but not overly so. There is good extension into the sub bass 20hz region, but there is a bit of a mid bass hump that sometimes bleeds a bit into the mids. Midrange quality is engaging and not recessed. Vocals and instruments come through with clarity, without distortion, even when approaching the 95+db range. Highs have notable extension, with a slight roll off. Without measuring gear to confirm, I'd say the mids and highs on these are neutral and are true to the R-Studio name.
Rap/R&B/EDM gave the most enjoyment from this signature. Classic Rock and Metal sounded great too, but the bass hump overtook some guitar frequencies on occasion, masking some clarity. Soundstage was excellent for a closed back, dynamic headphone.
The R-Studio can also be driven with ease from an iphone/android smartphone/tablet. It can also EQ very well, and took a +10db 30hz bump and other bumps and cuts with ease. Running them into an amp further increased what they could do.
You get a lot here for a $74 headphone. The R-Studio could be considered a cheaper alternative to the V-Moda M-80 and M-100, taking cues from a few of the better sound qualities of each model. The R-Studio has more bass extension than the M-80, and extends a bit further in highs. The bass extension approaches an M-100 signature, which is both a good and bad thing, as some clarity is sometimes lost in the mix from the extra bass push. Remember, the M-80 and M-100 are $199 and $299. A $74 headphone with the sound quality of a ~$200-$300 headphone is an exceptional value.
These aren't going to replace your flagship $600+ headphones anytime soon, but they are one of my favorite new portable headphones. Highly recommended.
