Great product. Use them in call center and they last and reps love them without a cord attached. I have over 40 in use and only had to replace 1 in past 5 months.

Headset has way too much static/interference issues. Even if/when you move any/all sources of RF interference away from the headset/USB dongle, it continues to pick up interference even the headset is 2-3 feet away from the USB plug. Returned and replaced with same product - exact same problem.

These are more comfortable than the other Mpow brand I bought but they are still not noise cancelling and it was often difficult to hear the conversation on the other end. I needed a more comfortable headset to make client calls in a busy and loud rec centre cafeteria.

Build quality is cheap. Wire across top is falling out. Whole thing feels cheap and flimsy. Audio quality is just very average. Radio reception is also quite poor and even messed up by sustained Wifi traffic. Compared to the Rapoo H8030 2.4GHZ Wireless Headset they are simply crap. I would have got a new set of H8030, which lasted over 2 years but could not find them anymore. Not wanting bluetooth ones, feeling very sad that this is the best Logitech can do.

Sometimes this headset works fine. Sometimes, the audio crackles horribly and often the microphone input gets so distorted people can't hear what I'm saying. I've tried every software solution, and the problem is clearly the hardware.

The concept of the headset is great, the implementation and practical use is just not there. After charging the headset battery for 3 hours, I started the setup. The Nano USB used on this headset unreliable and is sporatic at best. The instructions say not to plug it into a USB hub.

Response time and they just did not work

Had a Logitech wireless headset prior to this one and that old version was great. This one (H600) has very poor wireless range, about 1/2 the distance of my previous one. Also, the connection time is terrible, it takes about 5-10 seconds to connect when you turn it on and that may not seem like lots...

I bought this bluetooth headset to use on my PC and iphone. Supposedly it supports BT 2.1 including HFP and A2DP. After talking to Logitech support it actually only supports headset functions on a PC with their receiver and will only support headphone functions for music, etc.. on the iphone.

East set up on PC

Does not support headset functions on IOS (only headphone

I highly recommend this product for anyone looking for a quality headset to keep with them while traveling or casually wandering around the house listening to music. They have proven to be well made and maintain a stable connection, which truly cannot be understated.

I have owned a pair of these for a little over two years, and I can safely say that: 1- This Headset is very sturdy; I have packed them and repacked them, dropped them, crammed them into my pockets, and let my 7 year-old use them.

1- While these hold their connection pretty well; and won't lose it once they get it; they do have a periodic habit of needing to be restarted or re-inserting the USB wireless port in order to make them connect when first turned on.

I've used Logitech headphones before, and been impressed with the quality of both headphones and sound quality. So when my last set of headphones died, I took a friend's suggestion on board and went for a wireless set.
