Since I'm local to EarWerkz here in Atlanta, I made an appointment with Jack and stopped by their facility this morning to audition some of their lineup.
A little background: I've only been a user of universals as it's hard to find anywhere to demo headphones here in the US. Universals are easy to sell if I find the sound signature isn't for me or I have other reasons for disliking a particular set of IEMs. Also, I found that I've mostly gravitated towards warmer and more energetic sound signatures and hybrid IEMs in particular. I'm pretty treble sensitive and have been using the Shure SE846, Aurisonics ASG-2.5 and Sony XBA-Z5 most heavily over the last year. At the same time, I miss well-textured, detailed treble that those IEMs can be lacking in due to their smoothness, with the Sony Z5's treble being the most well-defined and detailed of the three universals without being fatiguing or sibilant.
I started out with the Legend R since this was what everyone was raving about. Jack warned me that the demo Legend R I was listening to had no burn in and that the sound would open up a bit more. However, I found them fantastic regardless. Shotgunshane's review of the Legend R on Cymbacavum nailed the sound signature of these. They're relatively neutral with an ever-so-slightly warmer sound. Bass is present and impactful, but plays a more naturally complimentary role being not as intensely thunderous in quantity like what you'd get with a dynamic driver. For a BA IEM, the Legend R's bass is very well detailed, however, and goes surprisingly deep into sub-bass. I tried a few tracks by Big K.R.I.T. that really get my car's 10" JL subwoofer rolling and the Legend R handled them with aplomb. Mids were smooth, darker and warmer compared to the rest of the EarWerkz lineup that I tried, but very detailed and lovely. The treble is the real star of the show, however. The treble of the Legend R is incredibly detailed and clear, yet shockingly non-fatiguing. In my experience, balanced armature-based IEMs often have very thin sounding treble that drastically affects the realism of cymbals and drums and guitar distortion. This sort of sound turns snare drum hits into more of a thin, digital whip-crack sound than a full-bodied snare hit. In comparison, the Legend R is lifelike and full-bodied with no thinness or artificiality in reproduction. The engineers at EarWerkz somehow created a wonderful treble mix that is both highly detailed yet also smooth and non-fatiguing. After enjoying the Legend R for awhile, I began to throw every single treble-happy song that's given me trouble with brighter IEMs I've owned in the past. The Legend R seemed to adapt to every track and delivered to me nothing but lovely and detailed sound. Imaging is another strong point of these IEMs. They don't have a staggeringly large soundstage, but the imaging and separation were top-notch.
I also tried a few other of their lineup, including the 6, 5 and Supra. The Supra was probably my second favorite behind the Legend R with a similar neutral sound signature but being a tad more energetic with mids and bass being a bit more prominent in my demo. I didn't love the 6 and 5 as I found them to be a little too sharp in the treble which doesn't correspond well with my preferred sound signature, but they were also quite refined and detailed, although not on par with the Legend R IMO.
Inevitably, I returned and spent more time with the Legend R and didn't bother trying the 4 and 3 as I was just so enchanted with how refined, full and detailed the Legend R was. Before long I pulled out my wallet and asked Jack, "where do I sign?"
Big thanks to Jack for the wonderful customer service, quick e-mail responses while setting up my demo session, and just overall being a great guy. He gave me a tour of their facility and asked me for tons of honest feedback on their lineup and it became clear they wanted to keep improving and developing their products for audiophiles. Also, big thanks to Dean for the wonderful engineering of the Legend R and answering my questions about their company. I can't wait to enjoy my Legend R!
