Review: Apple vs Google USB-C Headphone Adapters

[doublebstyle]

The EU one will drive the 560S to 100dB SPL Peak.

Personally, I'd have to reduce the EU dongle to about 25% volume for comfortable loudness, so still tons of headroom for EQ and high CF recordings.

Same here using EU version on PC with ADUM4160 isolator to drive HD599. %30 volume is more than enough for me

Hi, everyone. I have the eu variant (A2155) and I had always used it on my pc. Today I purchased Usb Audio Player Pro for my android phone and after setting hardware volume control to 0db, it is much more louder than it is on my pc. Do you experience the same thing? Or is there a problem/wrong setting on my pc? My headphones are Sennheiser HD599.

Hi @vycmajoris! Welcome to ASR.

If both the PC and phone are set to 100% Hardware volume and bit-exact audio playback, then they'll play equally as loud via the A2155.

Always useful to have a multimeter on hand to troubleshoot output voltage/loudness issues.

Well, I am so stupid I just checked audio settings on Spotify app and "normalize volume" setting was on. Apparently it lets you choose one of volume levels which are quiet, normal and loud. Mine was set to normal. It reduces volume by a considerable amount.

On one hand I am glad that my tiny dac just got much more louder but on the other hand I had been craving for more volume for 6 months and one silly setting was all I needed

Thank you for quick reply. Have a nice day.

offer topic but by any chance anyone can share a link to where i can buy a GMLR USB_C male connector? So i can wire my own 3.5mm female TRS

There is no such thing as a GMLR (Ground Microphone Left Right?) USB-C connector.

Back in the day, when USB-C was just introduced, some rare devices used USB-C for analog audio output with passive adapters.
AFAIK currently Audio Adapter Accessory Mode is even no longer in USB spec so active adapters (with DAC/ADC chip inside) are the only option.

I dont have need for an DAC USB-C, I need a passive USB_C to 3.5mm or a USB_C bare connector w/ GMLR so I can make my own. My headphones uses USB_C connector for analog and DAC USB C adapters do not work. The USB_C to 3.5mm that comes with it is too short and I dont want to use couplers so I rather buy a whole 6ft cable with a passive USBC to 3.5mm at the end, that is passive
