UE Live impressions
Bass is big especially on mid bass. the first time I listened to this it reminded me of the sennheiser IE8/80 800, Xelento
I am impressed despite for me having a mid bass hump it is very well controlled tight and FAST. The Live is a DD warm signature. This is not an always bass ON iem but when impact and slam calls for it
it delivers it in big sound but not on the level of ie800/s and xelento imo. It is also deep but I thought it is more focused on the mid bass. Drums are very well portrayed, weighty and solid as well as the notes. They are very engaging when the mid bass starts to show giving me that "Live" feeling. Though those who come from a bright or clarity focused signature might hear these a bit muffled.
the mids are well detailed. Bass for me does not bleed into the mids.Vocals have a nice timbre. It is clear and does not drown out on complex passages. But they are not forward like the 18+.
It sounds thick on the lower region and could sometimes project forwardness (imho, 160Hz-315Hz). It is lush, organic and also sweet. It does also have the micro details on its vocals. High mids have a nice presence particularly at the 2kHz region or slight bump giving it some clarity(maybe just on my ears as I also experience some ringing at 2kHz on planars, Audeze). Pianoes sound accurate and has a sweet tone on them for me.
The highs are refined compared to my 2nd gen 18+. Sometimes gets hot and give me sibilance(sensitive to sibilance, my right ear canal has a bend) starting from 6.3kHz to 8kHz and slowly dropping at 10kHz and so on (I wonder if the custom version has these). Giving it spark and also shimmer compared to my 18+. Extension for me is good and enough but not highly extended.
Soundstage is huge accompanying its big bass. Instrument separation is also good even with a bassy signature. Layering is similar to the 2nd and 3rd gen 18+.
Like what is mentioned, for me it is also a unique tuning. Ime, on a hybrid design, I sometimes feel the DDs being disjointed or not coherent on the whole presentation like the bass, mids and highs are differently tuned. I didn't feel this on the UE Live. The coherence I get from my 2nd gen 18+ is also what the Live has imho. I thought it has a very good fusion with the BAs and a DD coherency if I'm not mistaken even besting my 18+. The whole presentation is warm, controlled, very good transition and smooth. It sounds one as a whole for me.
Hope this helps
