Great sound, phenomenal noise cancellation, solid fit (not exceptionally comfortable, but not bothersome after 4 hours of continuous use), and seemingly reliable.
I've seen reviews claim that these may cut out a bit or be unreliable Bluetooth-wise. I've used them with 4 different devices, and I can tell you that they're as reliable as the device they're connecting to. One of my 4 (a Samsung Tab 6 Lite) is known for having bluetooth stuttering issues, and they do prevail here, but between my laptop and 2 other Android devices, I have zero issues. In fact, I can leave my phone in my home office and pretty well go wherever I please within my home and have zero connectivity problems (and yes, there are walls in between)!
My ONLY complaint/gripe (which is VERY minor), is that they timeout pretty quickly. That is, they're very quick to disconnect and/or shut off if you're not actively using them. I use them for yardwork and such, and if my Podcast ends and I don't start something new within a few minutes, I have to go through and re-connect before I can listen again. It's a bit frustrating if I'm trying to keep moving, you know?
Sound is great. Like I said, noise cancelling is really good also--which is why I use these during lawn chores and most recently, snow-blowing, because I didn't have to worry about hearing protection and could also listen to some podcasts.
They're great during a workout/on a run. They're very secure--I never felt like they might come loose or fall out. The only exception there was when snow-blowing, I had on a hat and because my hat shifted, it kept re-orienting the bud in my left ear oddly--but I don't see that as the fault of the bud. It maintained its seal, just got cockeyed, so it made it hard to hit the button through my ear.
The buttons are a bit hard to press--what I mean is if I want to turn it off, or do anything that requires you to push and HOLD the button, you're pushing it INTO your ear, which is uncomfortable to say the least. I don't know if there's a good fix for that, because I wouldn't want accidental button presses to throw me off either.
It's super convenient to have a case that recharges these buds. I have never had to recharge the case out of necessity. Days go by and I get the thought "Hey I should probably charge this," but truthfully, I've never 'had to.' In that, I always take the buds out of the case at 100% charge once again, which is super convenient and incredible.
The case is small and I'm bound to lose it at some point--I've recruited my wife's help in finding it twice already!
All in all, great buds. My 3rd pair of Jaybirds. I'm a fan!
