    Do any of these dongles drive a 300ohm headphone? I'm using a Mini Open, it doesn't need a ton of power and isn't on the hd6X0 level of scaling. But I do notice a step up in bass when I go from things like 3.5mm headphone jack to my Shanling M0 to my SW51+.

    Apogee Groove is supposed to be specifically designed for high impedance headphones

    Does the RU6 or Lutoo S1 work out of the usb c port of a MacBook for anyone else? No matter what I play I get like 3 seconds of sound and then it goes silent. It would a cool alternative to airplay and my LauX. And no draining an iPod touch battery in like 10 minutes.

    I haven't had a single problem running RU-6 out of my M1Pro MBP on Monterey 12.4. Maybe check audio midi settings and make sure all sounds, both system and audio, run through the RU-6?

    Is there any way to plug in an iPhone to get power while having a dongle like the RU-6 plugged in playing?

    Someone told me that Apple’s dual connection cck connector would work which has a female usb a port and a female lightning port but it won’t charge the iPhone through the usb a port. It will only send data.

    is there a way to make this dual cck adapter work or is there another adapter on the market that would work? The dongles drain the battery so fast I’d like to be able to hook it up to power at the same time when I’m stationary.

    I’m surprised no one makes an OTG cable with a Y split into 2 cables - a male usb c and a female usb c for charging.

    This is great! This will work just fine, going to order one. I can't find a USB A male to usb C male OTG sized cable to use with the dual port apple adapter.

    There should be a USB-C->A adapter included with the RU6.

    Try plugging in lightning cable to the CCK, then CCK to iPod, and then the RU6 to the CCK.

    Also I didn’t think to double check this, are iPod touches compatible with the USB 3.0 CCK? Do other dongles work using the CCK?

    I just tried it with my iPhone 12 Pro and both RU6 and Shanling UA5 and the same message appeared. Oh well I’ll give the adapter that @shotgunshane linked to a try.

    Woops I had the cables plugged In wrong. The lightning port has to be for charging and the usb a port for data. I got it working now. Endless BANDCAMP with the RU6!

    I always used both the dongle and my phone volume controls, hybrid between both. I adjust my dongle (E1DA 9038SG3) volume via the associated app to make 50% on phone volume to be ~60dB.

    Then I tired the extremes, 100% on my dongle then adjusting via my phone or %100 on my phone and adjusting via the dongle app (I think this applies to most dongle with physical volume control as most are digitally controlled).

    Results are kinda unexpected, using the phone volume control (Samsung S21+) the mid and upper bass is much fuller but noticeably looser. Everything else is much grainier and the treble is rough and brittle. Really hard to listen to.

    When I used the dongle to fully control the volume everything becomes tighter including the imaging. Resolution and refinement is two notches up. I lost the bass fullness but I'm fine with that.

    I'm not sure if this effect applies to all phones but I thought it's worth sharing.

    TLDR: never make your phone volume control to go lower than %80, the lower you go the grainier and low res the sound become. + soft transients and brittle treble.

    Are there any good portable DAC/Amps that also have an analog microphone input? I had a Schiit Hel but sent it back because the volume pot was bad. I have found no other portable devices that have an analog mic in. I do consider the Hel to be portable enough for my needs.

    I never thought I'd be in the market for a portable DAC/Amp but I think I can use one now. I've been traveling with my MacBook Pro and Meze Empyrean to work remotely. However, I also need to use a gamer bro headset (Drop/Sennheiser PC38x) for its microphone in order to participate in web meetings. The PC38x has a split cable so I could try to use the analog input of the MBP with a TRRS adapter and then the DAC/AMP separately but it would be nice to get a better mic input if possible. That's also some cable spaghetti that ruins the appeal of portability.

    I ultimately wound up with a Schiit Hel2, but when I was shopping around for something similar the other options were a Soundblaster G6 or Sennheiser GSX 1000 (each brand has a few different models to look up)

    I've had a Soundblaster G5 and G6 in the past that I used for gaming. They were OK but I ultimately got rid of them because I have a motherboard now with decent enough onboard. I had not thought about trying those again for portable purposes. I had hoped there would be something more audiophile grade these days. I am using an Asus ROG Clavis because it came with another motherboard that I had. It is OK, but the Meze Empyrean really needs something better. I've stuck to the Clavis because it has TRRS with microphone capabilities. I am getting pretty frustrated that there are not more options with this capability in similar form factor.

    Nice! I didn't realize the Fulla also had mic input. The Fulla is shipping right away and well within impulse buy pricing, so I went ahead and ordered one.
