MAIRDI Office Headset with Microphone Noise Canceling, with RJ9 & 3.5mm Jack for Landline Deskphone Cell Phone PC Laptop, Telephone Headset for Call Center Phone, Work for Polycom Avaya Nortel

This MAIRDI headset works well with both my cellphone and my Plantronics telephone for my landline. The audio is as clear as you can expect for a telephone; there is no static, and the audio is as loud as I want it, and the person on the other end can hear me fine. The headset comes with some extra adapters for telephones I don't have, so I can't speak for them. If anybody cares, my Plantronics telephone is the ancient SP-04 model, which uses an RJ9 connector between the phone and its headset. Swapping out the plantronics headset with this Mairdi headset was effortless. My only complaint is the earpieces are smaller diameter than I prefer. They press against a smaller area on my ears than other headsets, so maybe my ears would get sore after a few hours (long COVID conference calls).

I started working at home and needed a headset! So many to choose from and didn’t want to spend a small fortune so I picked this one out. Had no problem attaching it to my phone. Surprisingly it’s very comfortable on my head and ears. Plus does cancel a lot of the background noise , not that it’s really noisy in my home office. Cats for co-workers at home. Lol!

Piece of garbage. First it took awhile to find connector to use with headset. When I started using headset (for work) the customer said I kept cutting out. I do not recommend.

People can't hear me well unless I hold the mic as close to my mouth as possible. Otherwise comfortable and works well

These are not bad head phones, but the mike boom is short and people said they could not hear me well. when using the 3.5mm jack, I could not hear the through the headphones very well.

They worked pretty good

I needed a single headset that could connect to my office Mitel phone and to my laptop using USB for skype/MS Teams, etc..Bonus would be to also have a mini-phone plug that could connect to my iPhone 6sBonus-Bonus would be a quick connector so I could quickly move between my Mitel and my PCcheck, check and bonus-checkThe icing on the cake is it sounds really good and cherry on top is the price.They bought me a Jabra USB at work, and it sounds good, but not better than this and it cannot do all the connections this one can. I have recommended it to the IT department here to use instead of the Jabra

This headset works great with my office phone, an Avaya 2410. Sound is clear. Everyone states they can hear me clearly and that it sounds the same as my headset. I like the fact that I can plug into mycell with the included adapter if I need to take a conferece call on it.
