I like most of the ifi products I have used so far. But if the case is not pocketable, that ruins the whole point for me.

As a bluethoot is that the best thing you would recommend or do you think there is qualitatively the best ?

Unfair to judge the Pods using an iPhone. Pair it with a good Android phone and be amazed about sound quality via LDAC codec.

Regarding what you said, that you cannot power on the GO Pod unless you will put it back in the case, this is not what I've observed. When I am wearing my GO Pod and stop the playback, it turns off after 10 minutes. All I have to do then is tap and hold the touch buttons of any earhook - I prefer the right one - and after like 2 seconds, a distinctive sound is heard and then the voice, saying: LDAC. This is how the GO Pod works for me with my Samsung S23 Ultra. I do not need to put it back into the case and take it out, to power it ON, after its auto-shutdown.
