Phone Headset with Microphone Noise Cancelling Corded Telephone Headse with 2.5mm Jack Dual Ear Call Center Office Headphone for Panasonic KX-TGF574 KX-TGF380M Cisco 303G SPA504G 528G Vtech Uniden

I bought these headsets due to the advertised 2 year warranty. However, when they came, there was no warranty card or explanation, so I contacted the seller. They sent me a warranty document that is useless. The address on the warranty is:Xiamenshi Xianganqu Xiangfu 5li 10hao 1403shi Xiamen Fujian 361101,CNWhat is this? is this where you have to ship the headset when it fails? What does CN stand for? Cambodia?The rest of the warranty reads:Warranty DeclarationWe,Xiamen Meikajia Electronic Technology Co. LtdHere we would like to declare that:MKJ warrants headsets against defects in material or workmanship. Under normal use and services,all headsets are with 2 years warranty. During the warranty period, the defective headsets will berepaired or replaced as determined by MKJ.Warranty does not apply, if1. the warranty period is expired2. the warranty label is broken or removed3. the defect was subject to abuse, improper use not conforming to product manual instructionsThere is no warranty label on the headset. There are no directions with the headset. When I contacted the manufacturer about these deficiencies, there was no reply.Aside from that, the headset seems pretty good. I like the padding on the ears, and the sound is loud and clear. However, all the phone headsets I have got from Amazon have died within a year, and I don't see that these would be any different.I just used them, and they don't work. They failed after about 1 1/2 months. I have given up on the phone headsets. While they are handy, I have not gotten one that lasted more than six months in years. I found that my phone has Bluetooth functionality, so now I use a Bluetooth headset if it seems like I will be talking for a while. If you enjoy hands free talking, look for a Panasonic headset with Bluetooth function, and get a little earpiece like this one for about $20: https://smile.amazon.com/gp/product/B07FTHQY6Z/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1. It works just fine.

So, I can hear everything fine, however units on the road can barely hear what I say. I have to almost yell just so people can hear me talk. I got this as a replacement to my old headset that I've been using for 5 years now, very disappointed that I cannot communicate as I should be able to. (911 dispatcher) I've been in the field since 2011 and I've only had 3 headsets, this one is better than my very first headset but way worse than my last one.

No sound control. Very loud.

This is a real piece of JUNK.. It is cheep but no one can hear me talking... I can hear them great. But they cannot hear me... NOT worth the money....

I do not like a headset that goes over the head, but the ear wrap unit I have always used is no longer available from any supplier. This one is ok, but not good for me.

For the price they work fine.

I thought having two earpieces would help but the max volume is low, and my voice doesn't come through the headphones. I'll keep looking.

The head band is small and the unit does not stay in place.
