I hate adapters that come with a length of cable flapping around - and found this rather lovely DDHifi one from audio concierge.

Thought I’d share in case others were looking for something nice and solid

They do a nice 2.5 to 3.5 as well

Very nifty products indeed. I have the DJ44 for when I use 2.5mm terminated cables on my R8 which is 4.4mm.

Same. I actually got mine in the post today.
They are very well-made, they don't affect the sound (at least to my ears), ale the 4.4 mm jack feels more secure in the M6 that the 2.5 mm does. I got them both just in case and really happy with them. ddHifi did really well with them.
