This is all too common and quite repeatable for me. As soon as it gets "too warm", it's guaranteed the "pop sound" is coming up. There are too many reports of this from different users for it to not be a high priority fix. It's incredibly frustrating. @Shanling ? As an aside, I have reported a...

I've narrowed this down to the exact scenario and is repeatable: - 2 Bluetooth connections to the UP5 at start up, iPhone and Apple watch - Walk away from the Apple watch far enough such that it disconnects - Intermittent beeping starts immediately and lasts approximately 10 minutes

iPhone 12 Pro. iOS v. 15.6.1

No beeps when using M8 as source and if I disconnect from M8 and connect to iPhone, no beeps. Surely someone at Shanling has some idea what would cause the UP5 to generate 2 fast-beeps for any reason? Also, the beeps also occur on the iPhone connection when no music is playing, so it's not...

Nothing has changed as far as I know. I’ll try it with my M8 tomorrow to see what happens.

Recently, after turning my UP5 on and connecting to an iPhone there are two audible fast-beeps about every 60 seconds which continues for about 5-10 minutes and then stops. This happens regardless of how fully charged the battery is. It only occurs when music is playing. Firmware version 1.6.3...

This is a far too common occurrence for me as well, mostly with the Shanling player, but sometimes (rarely) with UAPP, which is what I use exclusively now to avoid the problem for the most part. It's quite disappointing.

FYI, I contacted them through the lightharmonic.com website on 1/7 and received one Stella and one Mera on 1/10 via their exchange program. Amazingly fast turnaround.

Tried this today and it did work. Thanks for the suggestion

I can't say exactly when I first noticed it, but I am quite certain it was occurring prior to the latest update.

Ditto

Yes, mine has this exact same issue at times.

Let me re-phrase...something akin to the plastic case w/clip that comes with the UP4. That doesn't seem "impossible".

Is there or will there be waterproof/sweatproof case for the UP5?

Looking forward to the UP5 release. Love the UP4 for workouts and will use one for home and one for the road. I pair the UP4 with a modest Soundmagic E11 and the combo has been indestructible as far as being impervious to sweat. And the sound quality for such an inexpensive setup is surprisingly...
