I'm beginning to think that might be my phone too... And those were tiny drop outs of a fraction of a second.
The sound really was that good. I had to send it back as I wanted more for the money, but it's one I really miss.
Otherwise I'd suggest you look for reviews of Astrotec S60 (Knowles BA driver - I expect it'll have better base response than mifo O5 Professional), or wait for Shanling to release theirs (also Knowles BA).
Have you considered TRN BT20? Bulky and no charging case, but you get whatever sound you want depending on the IEMs you choose (and changing sound just takes a new pair of IEMs). Also, the connectivity in those is absolutely rock solid - easily better than any other I've tried.
Bro, just how many wireless earbuds have you tried? You are the wireless guy. I am having a good run with the one I have for now so I will just wait for the ultimate.
