Best value IEM phones for travel use from Android.

I do international travel a few time a year and use a few IEM. For $150, Sennheiser HD1 https://www.amazon.com/Sennheiser-HD1-Free-Bluetooth-multi-connection/dp/B075JGSF2V/ref=sxts_sxwds-b... at $90 is not bad, phone call voice is clear, music is decent and extremely light. Two things I don’t like is the 6 hours only battery life and strange charging reminder. Shure SE215 https://www.amazon.com/Shure-Wireless-Earphones-Bluetooth-Isolating/dp/B07W6S15P4/ref=sr_1_4?dchild=... at $80 is my recommendation, it has MMCX adapter so you can use either Bluetooth adapter or change to wire. I don’t like the mic on BD2 because it’s on the pendent so speaking voice is hard to hear unless you clip it to collar. BD2 has 8 hours battery life and tells you remaining life each time you turn on. I use a Shure 535 and BD2 for many years so 215 should be a good choice.  I also have an old Shure noise cancellation add on wire so I can turn on pass through and not miss any important announcement.  Safety is an important thing in travel.

I did buy the Tin Hifi T4 iem from Drop.
They have now shipped and should be here Saturday so we will see as I fly from Jax to MSP Monday morning and that will be their first test.

Congrats!  Be interested to hear your impressions once they break in a bit. 

Its often true you get what you pay for.   If you have a good source, it would be a shame to devalue the sound with a headphone that might not be up to the job.   I know Grado, Shure, Sennheiser in ear models...all good.

The Tin T4 showed up today and first impressions playing them through my main system head amp are very favourable indeed.
Very efficient and a lot of nice solid bass without being one note boom, boom bass.

Using my phone which is how they will be used on the plane they did lose a little of that bass impact but hardly surprising tbh.
Overall pretty impressed for $79 shipped from Drop.
