So my little brother is a self professed Apple fanboy and really likes his Airpod Pros (the 2nd gen with Noise cancellation). For <$500 what is an IEM you think would be a great starter that would wean him off his obsession? I should add he also has the Airpod Maxes for his headphone set too.

This is a gem of an IEM that has been under the radar; really should be put in the same conversation as the Elysian Annihilators, the Noble Audio Kublai Khan's, the Jewels, etc I will state upfront that I have no affiliation with the brand and stumbled upon these by sheer luck, honestly...

When I was visiting Taipei from the US, there were many wonderful IEMs and headphone stores to try things out. Now that I’m back in the US it feels like an audio desert. Where do you like to buy your IEMS (online and in person)?
