I agree with you, it's disrespectful to not respond to the customer for two weeks...

Me too, i haven't any issues with my old phone (oneplus 5) and my Sparrow with stock cable. I am very happy with them...

Firmware control is not performed with an Android phone, a Windows 10 computer is required. In addition, I thought I would see the firmware version before installing the Firmware, but it doesn't work like that. However, once the Firmware update is finished, you can see the previous and next...

My Android phone is Oneplus 5, it is oldies but i am happy with my phone + Sparrow. No Any problem. iemLover

I did what you said, at 2.5mm balanced output and no noise was heard at maximum volume level. I wanted to update firmware with my friend's computer, but it already had the latest firmware installed. iemLover

But I have to say that something like a "click" sounds once in the 4th or 5th seconds of the beginning of a song. I guess it will be fixed when the new firmware is installed. I hope. iemLover

My cables. I have no idea if my Sparrow cable is new or old type. I just know it works fine. The other cable is the OTG cable the seller recommended to me. iemLover

I am using Mangird Tea iem + 2.5 mm KBEAR rhyme 8 core balanced cable. There is no any noise. This is interesting because i didn't check and upgrade the latest firmware yet. I haven't Windows 10 PC, i will upgrade the firmware tomorrow with my friend's notebook. iemLover

I purchased extra OTG cable with Earman Sparrow, seller suggested it, but there was no need to use the extra OTG cable, the stock OTG was completely adequate. I am using Oneplus 5 (4 years old) Android phone and there was no problem with stock OTG cable. iemLover

I see, many thanks. I will buy a MQA certificate. iemLover

Dear Milkdudd Milkdudd, i bought Earman Sparrow from Israel online store, i spoke with the seller before shopping, the seller suggested an additional OTG cable and he said: " I also suggest you take this OTG cable - it is amazing and improve the sound for sure - tested by my all audiophile...
