Really interested in this but was wondering if I would need to unplug it from my phone if I needed to answer a call.

Ok thanks. Also I wasn’t sure if the lotoo otg cable (marketing pic on page 1 of this thread) is a new version or one they sold previously.

It looks like the lightning cable for the S2 is different than the S1. Lotoo has redesigned the included cables to better shield any EMI/RFI. I use a choke on my S1 lightning cable that works great in getting rid of noise.

After looking at the S2 specs and comparing them to the S1, not a whole lot of difference other than output power. They both use the same AKM dac, have virtually the same feature set (other than some different eq/ate settings, and a remote button). I suppose the cradle for the S2 may come in handy for some, but not in my use case.

Since I only listen to iems, the extra power on the S2 isn’t important to me, so I’ll likely continue using my S1 with my iPad mini. But for those who are new to this fabulous little device, budget allowed, the S2 would be the way to go. Looking forward to impressions. ✌️

What choke are you using? The ones I have used haven’t really helped…

This one is made by TDK. Prior to its use, I would get RF noise, afterwards, silence. ✌️

I believe how the S1 and its cable is positioned relative to a source device will make more of a difference than what brand of a ferrite core is used.

Does your iPad have cellular built in? I haven’t had any issues with WiFi interference, but cellular plays havoc…
