Interesting, they definitely sound like they're aimed more at the hearing side of things than the sound side but they do look incredibly small and comfy. Could be a good one for those who like to/need to sleep with buds.
Hmm, no APTX on them and no mention of what chipset they're using, will be interesting to see if they sound any better than the Pro.
Also, with regards to discussion of IEM's, adapters etc, there are existing threads in the portable headphone amp forums that cover these but they're not very active. Ultimately this started as a thread about fully wireless IEM's, and adaptors that makes IEM's into TWS still fit that category to me.
