Hey everyone,
Got myself an Earmen Sparrow in the sales last month, been incredibly impressed so far for such a small unit!
I have had a couple of issues with it that I am yet to get a response from Earmen, the retailer or Tidal about, so I thought it might be worth seeing if anyone else has found a solution here.
Just to give you some idea of hardware - I'm using the Sparrow DAC with a Windows 10 laptop and a Samsung Galaxy S10 android phone. I have Tidal Premium and mostly use Mangird Tea IEMS and both a 3.5mm and 2.5mm KBear Rhyme 8-core 2-pin cable.
The first issue has to do with playing MQA through Tidal on Windows 10.
I have followed Earmens instructions here for how to play MQA files through Tidal on the Sparrow -

When I select "Use Exclusive Mode" and turn "Passthrough MQA" off I do get the magenta coloured icon light up on the Sparrow indicating MQA mode is active however it also automatically sets my volume level to 51 on Windows 10, which comes through incredibly loud (like, ear damaging loud) through my Sparrow. When I turn this down through the Windows 10 volume control (Tidal volume control is locked out in Exclusive mode) it automatically switches back to volume level 51 when the next track plays, which is incredibly jarring and loud as you can imagine.
I have not found any way around this, I either have to remember to pull out my headphones before the end of a track so I can quickly manually turn the volume down on the Windows 10 volume mixer or I cannot listen to Tidal MQA at all as volume 51 is way way too loud. Is anyone else having this issue?
My Sparrow is up to date with the latest firmware (ver 0.1.7982), this seems to me like it's an issue with Tidal, rather than the DAC itself.
The second issue concerns buzzing noises when plugged in to the 2.5mm jack of the Sparrow.
I'm getting electrical interference whenever I have a set of headphones plugged in to the 2.5mm balanced side which essentially causes a buzzing crackling noise in my right earphone in varying degrees of loudness and frequency (as in it intermittantly happens every 10 seconds or so) depending on what im doing on the device it’s plugged in to.
There is no buzzing at all when I have the same set of headphones plugged in using a different cable that uses the 3.5mm jack instead, I have also tested multiple phones (Galaxy S10, S20 and Google Pixel 3) but the same issue remains. The only thing I haven’t been able to test is a different 2.5mm 2-pin IEM cable as I do not own one, but the IEMs work fine on other devices with no buzzing when not using them with the Sparrow.
If it was just a slight buzz in between tracks I wouldn’t mind, but it’s an almost constant quiet buzzing and crackling in one ear regardless of whether a track is playing or not, and is especially obvious in quiet parts of a song or when the volume is low.
The only way I’ve found to stop the noise while using the 2.5mm balanced output is to actually hold the DAC in my hand. When I do this the buzzing disappears however when I don’t have it held in my hand the buzzing comes back, which leads me to believe there's an issue with the device itself.
As i've stated above, I downloaded the Earmen firmware updater and most recent firmware update, it appears as if my Sparrow already came pre-flashed with the most up to date firmware version (0.1.7982)
Cheers for reading,
