Same. they shipped out yesterday and arrived today.
100% there are launch issues. The Fokus app doesn't do much other than show the name either and the update doesn't go through. I did have slight crackling on the right side when first connecting, but that went away after disconnecting and reconnecting bluetooth. Might have just not properly connected first time around. Not sure if it's the stock tips that are behind it or it needs to be connected to a PC/ Desktop to update, as did a bit of tip rolling and source changing at the same time (between N7, iphone & PC) - was a bit sibilant at the start - too sharp/ artificial, not much bass to speak of and a wierd signature in general that threw me off.
Finally settled with the xelastec (standard, don't have the tws ones yet) and connected to PC. Not sure which part it was, but did get to a result where I am satisfied - though from the initial impression, was this close to returning them.
They are really good when working as intended, it's just the intended part.
I assume the change from sources is as there's different codecs. Not sure if anyone else has tried changing sources/ codecs/ tips just yet.
To nitpick, the case closing isn't the most satisying - the hinge feels a bit too soft and the snap close isn't as stong as other sets. Almost thought the usb-c connector was broken as it was loose on first use, but it was designed that way, you have to really push it in and it snaps in firmly. The design is smaller in width, but is stretched a bit long which might be an issue for some. The touch controls aren't very responsive, I'm used to the buds where you just touch it once and it recognises it - these not so much. Can't imagine doing a double tap or triple tap on these.
But on the flipside, when it is working as intended, they do get sufficiently loud. The signature is exactly as advertised, speed is prioritised, bass is there and more prominent than a neutral iem, but it's not basshead bass either - you can hear it more than enough, but the rumble is missing. The treble is surprisingly good, it's crisp and energetic.
