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. Source: Head-Fi Click here to view more

Below are excerpts from the review: All in all, after a ton of switching back and forth, I can confidently say that ddHIFI DH65B is fully transparent, does not have any signature, coloration or signal degradation, regardless of the cable, headphone, source or volume it is being used at. It has a negligible impedance as well as fully transparent design, so you can rely on it to use your favorite cables with a setup that’s notmade for them.

Below are excerpts from the review: Although this review is a bit shorter, it is due to the specificity of the product. DD DJ65B is a well-made and very well-priced adapter, it works without any problem and allows you to replace any 4.4mm cable with a large jack, which allows you to significantly increase their functionality and enjoy great sound without any interference. Some might see this as a degradation of such a cable, but there are many great S.E devices on the market, and this is a much cheaper alternative than buying a new cable from scratch.
