ddHiFi DJ44C / DJ44B: Adept Adaptation


Today we’re checking out some handy dandy adapters from the masters of accessories, ddHiFi.

The DJ44B and DJ44C are adapters that convert a 4.4mm balanced cable to either 2.5mm balanced, or 3.5mm single-ended. Definitely not something the majority of users will be needing, but, for those who do these are invaluable little tools. I was one of those that required these tools.

ddHiFi sent me their BC120B “Sky” cable last year in a 4.4mm setup, something I couldn’t use as I have no devices with a 4.4mm port. As a result, the cable sat unused for months, until these adapters showed up back in May. Not only could I now use the Sky, but I could fully enjoy the outstanding 4.4mm balanced cable that came with Astrotec’s Lyra Nature Limited Edition earbuds. But converting them to 2.5mm balanced and running them out of the EarMen Sparrow. Adapting them to 3.5mm was also a routine act so I could use the cables with my TEAC HA-501 desktop amp, and EarMen TR-Amp portable headphone amplifier. For those reasons alone they have been amazing adapters to have on hand. Let’s take a closer look.

Both adapters arrive in fairly plain, compact cardboard boxes. In one corner of the lid you find the ddHiFi logo subtly embossed, with the opposite corner containing a colour-matched sticker advising which version of the DJ44 is inside. On the rear of the box is the same product info, along with location and contact information for the brand. Lifting the lid you find some packing paper cut into small strips and crushed into a ball, a delicious silica gel packet (don’t eat it…) a warranty card, and the adapter itself tucked into an uncommonly thick little ziplock bag. It’s a very simple unboxing that produces little waste, especially since everything is recyclable, except the silica of course.

Removing the adapters from their protective bags, you immediately get a good sense of the build quality. The compact aluminum casings have a light pebbling around the main body while the tapered shaft leading to the jack contains faint stripes from the machining process. The gold coloured face plates contain branding and model info, along with a reminder of what is being adapted to what, along with corresponding male and female icons. All contacts are gold plated for improved signal transmission while a gold-plated copper shielding ring has been installed in the 4.4mm receptacle to ensure there is no interference from outside sources. Overall fit and finish is top notch with all the component parts slotting together tightly, free of extra glue, misalignment, or general shoddy craftsmanship.

In use the DJ44 models were great. The main body of each adapter is quite compact (20.8mm x 19.4mm x ~10mm) and light (B = 5.6g / C = 6.2g) so they easily link up with laptops, daps, phones, etc. without adding much more bulk than a typical jack would. The shape ensures there is no interference with dap or dell phones cases either which is appreciated. I didn’t experience any disturbances or cuts in connection when the adapters were spun in place, nor did I run into any compatibility issues. They worked just fine with every 4.4mm equipped earphone, and all of my 2.5mm and 3.5mm equipped daps.

If you’re in the market for a well constructed 4.4mm to 2.5mm, or 4.4mm to 3.5mm adapter, one made from premium materials with outstanding fit and finish and a visually pleasing design, the DJ44C and DJ44B should fit the bill just fine. While the price may seem a bit much for such a focused device, keep in mind the quality of materials and impressive construction quality. You get what you pay for after all. Overall a fantastic product.

Thanks for reading.
