Was tempted at $150, but nah. But for $100, ok I'll bite! (Main reason for me is because it's one of / the only true wireless earphones that supports AptX-LL - the Momentum True Wireless V2 does not!)
This is the version 1 of the Momentum True Wireless. Supposedly has great sound (see here), but has a battery drain issue (which can be mitigated with this fix by inserting a magnetic USB-C plug - meaning the case will stay charged for about 4 days (so will still need frequent recharging, but not as bad). Edit: See comments below here and here about the battery issues being exaggerated. I will leave all this here, just so people are aware there is a battery drain issue, but the extent of it, I can't say.
Supports: SBC, AAC, AptX & AptX-LL (one of the few/only true wireless earphones to support AptX Low Latency!)
A joke at the original RRP of $499, but for $100, it's not a bad option to consider (particularly if you have an AptX Low Latency Transmitter, like the Genki for Nintendo Switch).

Very pleased with purchase. I haven't noticed battery issues with my pair. They sound great and I have noticed no audio-video lag. I have also connected to my PS4 via Bluetooth transmitter and it works great, no lag thanks to aptx-ll.
Only downside is switching connection from one device to another, the only way to do this is to manually disconnect from current device and manually re-connect to another paired device, or re-pair, which gets a bit annoying. My old Bose Soundsport Free had a button (and also via app) you can cycle through all paired devices and it will attempt it connect to selected device, I would have thought this to be standard feature.
