Pros: It's comfortable to wear and the audio quality from the headphones when listening is good.

Cons: Unfortunately the microphone is not good. The pickup on the microphone is quite horrible. At maximum recording level it barely registers my voice. And the Logitech driver, such as it is, doesn't have a mic boost feature. I just bought it today at Be$t-buy and I'm returning it tomorrow.

Pros: Lightweight. Long battery. Fairly durable. Bluetooth AND USB dongle.

Cons: If your car is super noisy, it may not be QUITE loud enough. I have a very noisy car though. Also, It's very easy to lose the USB dongle. Figuring out how to pair the bluetooth was a little challenging, until I googled it.

Other Thoughts: It should probably be cheaper. But it's the best in this category I've used so far.

Pros: This headset has decent incoming and outgoing sound. It is also pretty comfortable.

Cons: After 1 year the charging cord died. After 1.5 years the micro usb receiver fell apart, but still worked it was just hard to plug in and dig out. After 2 years the ear cups both wore through to plastic and Logitech would not respond to me so I could get them replaced. Then I tried to buy them as a replacement part and they weren't in stock. On top of that if they were in stock it was gonna cost $11.

Other Thoughts: I bought this headset on sale for $50 and it wasn't to bad of a price. However with the limited lifespan of all the parts and it being very hard to get replacements with terrible customer service I would strongly recommend getting a different headset. I have already had friends ask me what headset I use and I tell them just so they know what not to get. I used to love Logitech products however their products and customer service have become below average and I would recommend staying away from their products for the time being until they decide to improve them.

Pros: It's very lightweight and great sound quality on top of very comfortable ear foam. It offers Bluetooth mode or USB with NANO receiver mode for your convenience and has all the essential media control (especially "mute" button) for quick action without searching for your mouse.

Cons: It does not wake up after the computer return from sleep mode most of the time. The quickest way to pair the headset back is to unplug the USB NANO receiver and connect back, then the headset will pair right away. Forget about the pairing software.

Other Thoughts: I had owned the Logitech H760 headset for many years until it's totally broken and assumed that the H800 would be even better. It is better in the overall design but lack stability. I would advice anyone using the H800 to use an USB extension cable for the NANO receiver so that you can conveniently unplug and plug when need to.

Pros: *Durable/flexible (wouldn't like to test it)
*Great sound quality (compared to my beats!)
*Long Battery life (I get 6+ hours)
*Longer range then 12m
*Great value
*Handy storage for micro receiver
*Very Light

Cons: *Buttons are a bit glitchy with Macbook
*iPhone glitchy when using buttons
*some minor connection problems
*you should be able to us it as a USB headset also, the cord only charges
*Microphone quality not very good, good for Skype calls, not recording

Pros: Rf and Bluetooth in one headphone

Cons: Could be a little Louder

Other Thoughts: I do not see what everyone's problem is with these headphones. They sound good have decent range and work with the RF nano receiver or bluetooth. In my experience the call quality is second to none whether on my computer or by bluetooth on my phone. I have a lot of bluetooth headsets and none are as good as these for making phone calls. It is always crystal clear and no one ever complains about it like other headsets I have when on bluetooth. I watch you tube with mine all of the time and they sound really good although I have wished they were a little louder at times when hooked up to my computer with the nano receiver. When hooked up to my phone however they are plenty loud but I do have Viper4Android an EQ booster root app. I have had mine over a year and have never had a single problem with them. As a matter of fact I think I may purchase two more of them one for my wife and one for my other computer unless I can find something more high end that does both bluetooth and Rf but I have not seen any yet !

Pros: wireless. decent enough battery life. can use while charging.

Cons: range.
durability. - mine broke in 3-4 months of normal use. never dropped, or thrown... crackled like mad one day, then stopped the next.

Other Thoughts: spend your money on a better set. I will be next go round.

Pros: Looks good and for some -- millions of buttons.

Cons: It broke, almost immediately. If you buy these -important- do not wear them while charging. The USB socket on the headphones is fragile beyond belief. A little torque to one side or the other and it breaks.

Next problem are it's way too numerous features. You can't touch the headphones without hitting one button or another accidentally. You don't need any of them.

A complete loss.

Other Thoughts: Went to different vendor and bought the similarly priced Logitech headphones. Pleased with their ergonomics but we will have to wait to find out if they're as fragile.

Pros: Functional enough for VOIP, fairly comfortable. Easy set-up. Decent battery life.

Cons: Not for audiophiles. The receiver/transmitter pair has JUST enough bandwidth to perform it's job, so if you are talking and listening simultaneously and the USB bus is taxed at all, you're probably going to hear crackling over the right or both channels.

Other Thoughts: Had I researched them more thoroughly, I might have bought another product. This is the first logitech device that's really let me down in such a big way.

Pros: Wireless, decent range. Holds charge for several hours.

Cons: Shabby USB cable for recharging, broke in a few months.
If sound is loud enough people can hear what your contact is saying or what you're listening to.

Other Thoughts: USB cable stopped providing a charge to the headset after a few months. I thought it was the battery at first but I swapped the cable and now it charges up fine.
If you care about privacy, keep the output volume low.
