My old drummer had Alien Ears triples.. had to send them back twice for BA failures and busted internal wiring.. Spent more time without them, due to turnaround and poor customer service.. They had been on my shortlist before going with 1964 Qi's 2.5 yrs ago..
I doubt I would go with them now. My A8's sound great and I retained the Qi's as backups.
I bought a custom cable (shameless plug here) from BTG Audio - the
Midnight CIEM.
There IS a lead time for them, but VERY excellent cable.. W-A-Y better than the stock cable. I was on my third stock cable in 2.5 yrs (but with much use). I put a straight-end 1/8" jack on the end of the BTG Midnight cable - makes for easier connect/removal on my G3 body-pak versus the standard right angle jack. Fits my phone better too!
My other guitar player has UE7's (triples, $850 base price) and a G3.. he loves them, because they are voiced for guitar.
