I don’t own the 5K, but I’ve owned other similar devices with USB-C in (BTR5, XD-05 Plus) and I quite like the Lightning-to-USB-C cable that Woo Audio sells:
Not the cheapest in the world, but it’s good quality and the double-right-angle is very nice if you’re carrying two devices in your pocket.
Hey guys, can you stream music FROM the 5K to headphones once connected as a USB DAC, or can you only RECEIVE music via bluetooth and output to headphones physically?
Full streaming and audio in works on usb. The rates are somewhat limited but it is a killer setup. probably the best gaming setup for the price. you can dual connect it with your phone on bluetooth and it switches on the fly. my current setup uses it like this but take the headphone output and inputs it into and asgard 3.
killer.
Is it just me or does this thing sound shockingly good for something so tiny?
Damn you tried out all of them?
I wish they added PEQ for the new BTR5 
Yup😉, still the new ifi on the way.
I have tried also Shanling UP5, but I returned it cuz of QC problems.
I think they are going to add PEQ on the international version + 4.4mm I think, cuz the BTR5 MQA is actually only for Chinese market.
The problem is that I can only get the chinese one 
International has insane VAT for me.
Also they are going to release it for Chinese market as well
Oh that’s good to hear, I haven’t seen any infos about it, where did you hear from?
From Fiio themselves on Taobao. The only reason they released an updated version cuz of the shortage for the old chips Sabre’s ES9219P.
Cool! I would love to see a 4.4mm port on the new model, I don’t like 2.5mm cuz the jack is pretty vulnerable when I do gyms.
I am the same. Hopefully the new portable Amp/Dac with BT from fiio comes with 4.4mm, and more power as well.
I have a microphone on my IEM cable, but when making and receiving calls with the 5k it uses the microphone on the 5k. This is suboptimal, since the 5k is on my belt. Does anyone know if there’s a way to turn off the mic on the 5k and prioritize the one on the cable?
Are you using the 3.5mm or 2.5mm out?
3.5mm output, SE
Not an expert on this but I think you’ll need to use the 2.5mm TRRS to use the mic 
Not sure I understand. Right now it uses the mic with the 3.5 input. I want it not to use the mic, so I can use the one on my cable. Are you saying you need to use the 2.5 port to NOT use the mic?
Again not sure how the 5k is configured I’m sure other folks on here can advise better than me on this 
You can select the in-line mic or mic on 5K in settings, but you need TRRS cable.
