Excuse the question but what smartphone are you using it with? Apple? If so, try it from computer or android and see if it has the same fault... if it doesn't, the problem is the iPhone... obviously.

Try different source as suggested PC (the best) or other Android phone (Apple is always finicky), could be USB chip compatibility. I believe HiBy FC6 had similar issue on SnapDragon 8 phones.
Update to the latest FW, check OP.

Have you tried to downgrade your firmware and them reverse?

I have Android phones (Pixel 7 Pro and Ulefone Armor 21) that I've tested on along with Mac Mini. It happens on each of them. Firmware has been updated but haven't thought about reverting back to the prior version. Would that be the same flashing instructions or could it cause an issue if I go back? I wouldn't think it would but having rooted Android phones, I know it's generally not recommended to flash previous firmware.

Also, MusicTeck got back to me and said because the W4 has a higher output (420mw), that could be why I'm hearing it here but not on other DACs. Are others hearing a similar sound?

Omg. If I knew that W4 is also buggy as was W2, I probably wouldn’t pull the trigger…

Ifi go bar has even higher outputs with zero issues. What IEM are you using?

Meze 109 Pro and Sony XBA-N3

Both headphones are not super sensitive, problem shouldn’t be caused by high power output.

You had defective W2, what was the issue?
@tmc414, how does it work on PC. If you have issues on multiple platforms, the problem is with the dongle, ask for a replacement. What you are describing is not normal.

It wasn’t defective, but it has a problem with M1/M2 Macbooks, at least for me this problem was fixed by firmware after 1.5 years. Some 3d party cables caused artificial noises that was fixed recently with firmware, after 2 years.

I’m selling my W4EX if anyone is interested. I haven’t used it at all since I purchased a DAP. It was only purchased just over a month ago from Hifonix in the UK. Will ship to UK only.

Apple woes, my condolences.

I thought that only apple products working with macos was a feature
I've never got any dongle or dap to work with any of my macbooks without restarting coreaudiod every few minutes

They surely are trying hard to keep it closed ecosystem.

Interesting.

I've used dozens of dongles, dacs & daps with multiple Mac computers over 10+ years. I've never, ever had to restart coreeaudiod.

I currently have 3 macbooks from different gens running different version of macos
none of them work properly with L&P, cayin, AK or ibasso
You must be one of the the lucky ones

Same here, never ever had any issues.

I have never had problems with Macbooks with Lotoo Paw S1 and iFi Go Bar.
Since Musicteck doesn't want to replace it, it means that LP is confirming that having a popping effect is not a defective unit and is probably caused by firmware.
When you contact the authorial dealer about replacement, they first request the manufacturer about the problem.
