Balanced Dongle Extraordinaire

I love this dongle. The 4.4 mm and 2.5 mm options are such a great choice. Most of my upgrade cables are terminated in 4.4 mm now and ddHifi providing that option is a major reason I purchased it. The sound quality is also excellent with a superb balance between analytical and musical. It is a good mixture of both ends of the spectrum. I highly recommend this product for the iPhone. Only slight negative is it does drain the phone battery a good amount sooner so just be wary of that.

My new de-facto dongle

Wonderfully clean and able to do a stunning job with even the 6xx so far. Wow, just wow this blows the Apple Dongle out of the water!! Finally a dongle to dethrone Apple, and it’s puny little dongle.

It's fine

I like the build, the pictures don't really sell how small this thing is, but design-wise it's first rate. It just doesn't have quite the oomph to drive my 58X's as hard as I'd like, but for a quick session when my BTR5 is flat or lost in a drawer, it's pretty good.

Work flawlessly on I phone 11

Turned my limited Apple device into a full Hi-fi player simply by plugging it in! I can Play Native DSD and Hi-res files (using a third party free music files player that is, Apple Music is only support MP3 and MP4, not Flac and such). Feed form the iPhone Battery itself. Couldn't be more simpler.
