How is Call Quality on the Pixel 2 & 2 XL?

Nope. No headset. I don't even own a bluetooth headset that takes calls. I do know that one of the people who called me actually made the call over WiFi, and since I was at home at the time, I would have also been on WiFi.

My first guess was that this was a Project Fi problem, and there a number of complaints about echoes on incoming calls on the Fi support forum, but I've also seen a couple Verizon customers on XDA making similar complaints.

Ah I keep mine all on cellular. From the handset, speaker, and BT in my truck so far no complaints. Verizon network here as well.

Which, near as I can tell, is the only workaround. Only it's the sort of workaround that makes both WiFi Calling and Project Fi seem effectively pointless.
 
Coming from an iPhone, I was shocked, yes, shocked, at how clear a phone call could be. The pixel is light-years better.
 
Coming from an LG G4 that I was happy with until or started becoming very sluggish, that did not affect call quality that I could tell, the call performance of my P2XL (128) is better..
 
The fact that I have had 4 people say have you got a new phone, I can hear you now suggests that it's better than my 6p
 
On T-mobile it's good.... No issues of complaints from people on the other end.
 
I'm on AT&T and call quality is fine. Although since I'm on the beta HD Voice is enabled so that probably helps as well.
 
Pixel 2 XL, call quality is demonstrably better than my 6P or 5X. Crisp and clear using T-Mobile.
 
The background noise cancellation on the Pixel 2 is remarkable. I've been in a crowded pub and the person on the other end has thought I've been sat in my car.
 
I've been plagued with the buzzing noise on all calls since I purchased Pixel 2 - Verizon. hoping 8.1 fixes it.
 
I've only made a few calls but call quality is fine. Much better than my 6P in terms of usable volume from the handset earpiece.

Pixel 2, tried it on both Verizon and T-Mobile.
 
Compared to my 2nd Gen MotoX the the noise cancelling is great. My wife would always complain about all the background noise. I would have to stop anything I was doing because any noise was amplified on her end. Now on the Pixel 2 I can wash dishes or cook dinner on her commute homw and she barely hears anything but can hear my voice very clearly.
