I found it is very unstable when use with iPhone13 (ios15.4). Both ok with MacBook and android phones.
I tried with few lighting to usb-c cables but nothing changed.



My luxury & precision w2 and lotoo paw s1 both can work great on iPhone.

Can you tell us what the RU6 setting (gain, volume, NOS or OS) and choice of headphones?

Regarding the USB cable, please make sure your Lightning to USB-C cable is good for 5V. Take the OEAudio cable for example, it explained clearly that:

Most of the Lightning OTG cables, which have output of 3.3V 100mA cannot fulfill the need for portable DACs. We redesigned the circuit, which the OEOTG cable can achieve a 5V 200mA output​

I tried four cables also the CS-L2C

I tried NOS and OS with both high gain and low gain. Volume around 35 -45
I think your device has some problems, my Ru6 just unstable when volume is above 70, below that value is stable, nothing happens, tried both CS-L2C and 2 DIY Cables.

Quick update:

I've been enjoying the RU6 + WA8 combo immensely. While it's not a dedicated line-out, it might as well be on the RU6 - clean dark background at 100 volume into external amps.

RU6 + WA8 is a portable unbeatable combo for vocals, jazz, blues... lush and wet~ Just beautiful.

Hi. Is it possible to use RU6 on iPhone? I have iPhone 13 Pro. When I connected RU6 to iPhone there is no sound from 3.5 mm or 4.4mm.

I'm using cable from iFi Audio xDSD GRYPHON - it works with iPhone and Ifi or other dongles I have (like LP W2), but don't work with RU6 :frowning2:

My RU6 works with my iPhone 11 Pro Max. I am connecting with the Cayin OTG cable that I purchased together with the RU6.

Nice! Amazes me that we are talking about the RU6 together with the WA8 in the same breath! The RU6 is such an outlier!

Haha yeah... it's amazing for what it does. Barely any reason for me to even consider getting a RS6 or a N6ii for R2R. I sometimes run the RU6 out through the 3Max even~

On the same token, the RU6 should pair very well with the C9 then. Interesting!

It is still very early in my usage but from the last few hours of use, I am very much happy with what I'm hearing. I tried some simple, loose A/B from the sources I'm using and can clearly hear the differences. I tried the OS a little but really liked the NOS much more. Love that this adds a new layer to my listening. So simple yet so enrapturing.

"Enrapturing" is a great way to describe it!

"There"
So, I have put quite a few hours of burn-in on my RU6 and it is continuing to impress. Also, I just got a new Samsung S22+ and the RU6 pairs with it perfectly. I was originally using the RU6 with my old Samsung S10+ and I was getting some intermittent noise/interference with a couple of my iems (Serial and Timeless), and I am happy to report that the noise issues are completely gone with the S22+. I love this dongle!
