Is that a planar IEM?

Why expand? You won’t have time to use/listen to the ones you have now.
Because if you are on a budget, you are less likely to need an amp of some sort or amp/dac combo to properly drive a dynamic driver or balanced armature. Even Electrostatic drivers are easier to drive. That’s the only driver I’ve ever heard that needed a little warm up period. Like a minute or three.
Less power required = more budget friendly
I learned almost nothing useful about IEMs from here.
I learned a lot from Oratory1990
Don’t start with a planar driver as your first IEM.

5.3! KZ gave us 5.2 Bluetooth in 2021.
Oh… yeah… you maybe noticing the loss of audio data from the audio being compressed.
What was the output source? Which iphone?
You're experiencing ear fatigue. Your ear drums are getting exhausted from getting pummeled by the same sound frequencies for too long. Sounds are applying pressure to your ear drum, so the airplane feeling makes sense.
If you imagine the noise canceling sounds as hitting your ear drum, but not giving you any audible data to react to it can feel confusing the brain.
I did a couple of sound experiments with gamma frequencies back in 2015, and we found after like 15-20 minutes of using these low non-musical sounds there was ear fatigue, and even feelings of frustration until the sound was turned off. It wasn't too loud or anything stupid like that. Just the same frequency for too long.
If you're using ANC to block out city/life noises like many NYC airpod users I know, you should get some ear plugs from Alpine or some company that uses soft medical grade materials and have at least 10-15 decibels of sound filtering.
Were you using spatial audio (Apple’s Dolby 360) mode or something? That sound effect happens with poorly designed 360 audio.
*I’m not a fan of Apple’s designs for audio gear. Their engineers made it clear several years ago, audio quality isn’t important them. Kind of like Spotify not having high resolution audio files.

Are any of your cans planar drivers? If so, how do they compare?
