Logitech Cordless Telephone & Pc Headset System

[1460 mAh] This cordless handset matches with our business phone system.

[Windows] I've had numerous of Logitech's more expensive non-gamer cordless mice and now this model is my favorite. Pros: light weight (and weight is actually adjustable with included parts), responsive, and great feel if you're right-handed. Cons: battery life seems shorter than for my previous Logitech mice; will not work if you're left handed. Bottom line, highly recommended even if you don't play games.

[Mechanical] This is one of the best Headset that Logitech has created. B&H had this headset on sale and I just had to buy them. I am glad I did and I like the sound quality and the mic is very responsive. You cannot go wrong if you are a game like me.

[USB 2.0] this works to connect my PC with bluetooth headset

[1.015 lb] It's like the best telephone connection ever.

[Yes] excellent headset device for PC based communications

[4 GB] Music on hold for telephone system continuous playing a Beach Boys CD. It continues to work OK. The door is a little delicate about staying closed.

[2.175 lb] The hanger installed easily and has a soft receptical that is plenty wide enough for my Logitech headset.

[23 Hz to 18 kHz] A great product. We're using it as part of a mobile, mostly cordless audio system. The back-compatibility with the previous generation was very helpful, as we already had an older set on hand. They talk to each other with no problems. And the versatility of battery or USB plug-in power is very helpful. Recommended.

[1010 mAh] Have had this system for years. Every few years I have to replace a handset which is understandable considering how much it's used. Not many other options for cordless 2 line systems
