Best value IEM phones for travel use from Android.


Just looking for ideas and suggestions from actual users of IEM head phones.

I travel..... A LOT!
Even in today's troubled times.
I get emails twice a day from Drop.com and the choice of IEM seems to be staggering and bewildering.

What do I need?
Relatively efficient.
Being driven by a Motorola Android phone only.
Relatively small tips, had some that just did not fit in my ears at all!
Budget... $150 tops.

Thank you and stay safe!

All the Periodic guys run around RMAF in Lab Coats.
@  Ha!  They MUST be good then.  Seriously though, thanks for the info.  Sounds interesting and will check them out.  

Pretty happy with the Tin4 right now but will check out the Periodic stuff.
Thanks

If you could get your hands on Onkyo E700M, they have been a spectacular hidden deal. Brilliant smooth transparent sound and tighter cleaner bass than most earphones I've ever heard even at 500 bucks. Because Onkyo stopped production of these, they're now found only in certain places like Singapore. Ignore the bluetooth version (E700BT), the E700M wired version was one of the best IEMs ever.
