Hmm, you've given me something to think about at least!
It's a bummer if the Bose QC II sounds bad for calls, that seems surprising with their design, and I recall Bose QC Buds (1st Gen) being known for having very respectable call quality when it came out? Sure, call quality isn't highest at my list of priorities within a TWS earbud, but I've also had some very nightmarish experiences with my older TWS earbuds where I got so damn mad as soon as I took a call that was somewhere where it wasn't completely quiet and people were always like "I CAN'T HEAR YOU, I JUST HEAR EVERYBODY ELSE AROUND YOU" *cough, WF-1000XM3, cough* and I'm not exactly looking to get back to that.
I really don't like the look of the Oppo Enco X2 unfortunately, I find the Freebuds 2 Pro to look MUCH better, both the silver and the blue are gorgeous. I do like white earbuds though, but I'm not mad about the super plastic-y looking Airpods-like finish on the X2s. But I also don't trust Freebuds Pro 2 because they're tuned by Devialet, and I just find the Devialet Gemini to be one of the worst tuned buds in my collection of all time.
The only thing that bothers me about the L3P's though is that I bought my first pair for $79 completely new and now they're back up at like $120-150 where I'm at. They are worth the full retail price though, but it still stings to buy the same earbuds for almost twice the money as the first pair.
