These are my first open back headphones. I am enjoying them greatly. Thank you good folks at Musiteck for your help and good service.
The U-Free are really good earbuds. They have a clean, neutral sound with no bass “processing” like many top-of-the-line TWs. In particular, the bass is dry and clean. Last but not least, the volume is really very high. Definitely the best TW's I've ever had!!!
P. S. An honorable mention should also be made to Mr. Andrew from Musicteck assistance, very kind and competent.

IEM users beware of noise floor, even for low sensitivity models like the Solaris 2020 (94 dB SPL @ 1kHz: 6.54 mVrms). It seems this is not an uncommon issue for even the most highly regarded portable DACs including the Chord Mojo, so not really a fault, just a mismatch. It sounds great with Focal Clears, but my only use case for the RU6 is with IEMs on the go.
