Below are excerpts from the review:
Sound quality-wise, the DJ65B perfectly does what it should do. It does not add color to the sound coming from the source device. There is minimal internal resistance, and I noticed zero loss in fidelity, dynamics, and sound pressure level while pairing the DJ65B with a few amplifiers. I tried it with a broad range of devices, from the sensitive Campfire audio Ponderosa to the hard-to-drive DITA project M and FATfreq scarlet mini. I noticed nothing odd or new while pairing these IEMs with the ddHiFi DJ65B.
