I'm a really big fan of the Plantronics Voyager Focus UC and specifically the gen 1 version, not the gen 2.

(For reference only, not suggesting buying from that listing)
I can't say anything about their lag. I've never noticed it but I also don't game with them. As for price, well my first pair was free from work. I've since looked on ebay and picked them up used in great condition for as little as $25.
OK, why do I like them?
1. They are comfortable - this is one of the primary reason I prefer Gen 1 over Gen 2. These are relatively light and designed to be on your head all day.
2. They work with two devices at once. I have a work and personal cell phone. These will pair with both at the same time. If you are listening to music on your personal phone, that will pause if you get a work call.
3. They have very good audio for calls. These headphones not only have noise canceling for you the wearer, but also for the people on the other end of the call. If you don't remember to lower the boom mike people on the other end won't hear you. On the other hand, if you have a noisy old pickup, well people will hear you, not the truck and road noise. Note that they have very limited passive noise blocking so these aren't like the BOSE where they really isolate you from outside noise. Instead they do a good job of cutting out background AC/fan noise, etc. They make a notable difference when driving my car/riding in a plane.
4. They have a good set of controls on the headphones. A dedicated volume control, play/pause, fwd/bk buttons, a mute button etc.
5. They have side tone. This is like an old school land line where you can hear your own voice thought the speaker. So if there is wind noise from your mic you will hear it. I recall my old StarTac phone had that feature but most phones after didn't. If nothing else, if the line goes dead the side tone will stop and you know the line is dead.
Mixed or bad things:
1. They use USB micro - it's a **** plug design but I do have a lot of them. You can also get them with a charging stand which avoids
2. The 12 hr battery life is probably based on not using noise cancellation. They will last me most of the day so long as I'm not on a bunch of calls.
3. They are an older BT standard. I'm not sure why that's bad but reviewers of other devices seem to think the BT 5.0 standard is better than 4.something.
4. They are not rugged. These are for the office, not the construction site. Keep that in mind when thinking about durability.
As a side note, I've really become a fan of several of the PLT/Plantronics models. Often it's because you can get refurb models off ebay for very good prices. I've got the Backbeat Go 410 (around the neck, BT earbuds that support two phones, noise canceling and side tone) and the Plantronics Voyager 8200 which is meant to be a larger, over the ear setup with better sound quality (more BOSE like). It's got basically the same features as the Voyager but better sound quality, more noise isolation and a mic array so there is no boom mic but you still get the great isolation of background noise when on a call. They also have much better battery life. However, since I am mostly listening to podcasts I don't use them as much as the other two. The Go 410 can typically be found refurb on ebay (properly clean/unused) for $20 or less. I use them till I break them then replace them.
Still with all that said, I can't say how any of them do for latency. They are all primarily about voice quality.
