Great pair of TWS earbuds!
Amazon link [amazon.com]
Same price on Walmart (just on the white color): Walmart link [walmart.com]

From Product description:
+ Up to 20 hours of music playtime
+ Approx. 1.5 hours charging time
+ Bluetooth 5.1​
+ Wide range of Bluetooth audio codec support (SBC, AAC & aptX codecs support)
+ Customizable ​touch controls

My thoughts
I got these last year at $129 before tax - excellent sound quality and clear calls - use them for work meetings and folks hear me loud and clear!
Subjectively, these are also the most comfortable ones from the many I've tried and returned (galaxy buds plus, galaxy buds live, Bose sport earbuds, jabras)

Couple of things to note -
Pros
Has equalizer within app
Wide codec support
USB-C charging
Usable touch controls
Solid connection

Cons
No multipoint, but switching devices has been pretty easy with app. (The product page does say multipoint is available, but I've had trouble with this and I stuck to using the app for this)
No transparency mode, won't recommend for biking/running therefore
No ANC (but good noise isolation)
No IP or IPX rating of any kind (thanks @GimmeYoTots)

Price just dropped to $90 this week. Sound Guys give these a higher rating than the CX and Momentum 2. At this price, they are a steal if your main priority is sound. I have them. They have no bells and whistles outside of a so-so app, but the sound is incredible!

Just to be clear, 20 hours is including the case. Here's some more detail from Sennheiser's product description page (link [sennheiser.com])
Quote :
7 hours on a single charge and a further 13 hours with the small, sleek and compact charging case.

I'm curious if anyone has tried these while wearing ear protection. Do they stick out from the ear to prevent from wearing over-ear protection while using?

Only the right bud can be used standalone

From product page
Can I use one single earbud as a stand-alone device?
CX 400BT True Wireless earphones deliver stereo audio via their left and right earbuds. However, the user can use the right earbud, which serves as the 'master' earbud to establish the connection to the paired Bluetooth device, as a stand-alone unit for phone calls and voice assistant access.

I don't own these but they look similar in size to other ear buds I own. Every week I have the ear buds with ears over them when mowing and weed wacking, no issues.

Haven't tried with any form of ear protection but they do stick out a little bit. Check out this youtube review - that's the first thing he talks about https://www.youtube.com/watch?v=2a1huHNnyfA

Seems like a solid deal, gave it a TU... but, OP, in the neg column you might want to add - No ANC (at $200 retail it's kinda expected), and No IP or IPX rating of any kind... so beware if using outside (in even light rain) for sports or running.

This is a major deal breaker for me. Lot of hassle with this, specially for long duration calls
