Onvian RJ9 Male to 2 3.5mm Female Headset Phone MIC Audio Splitter Adapter Cable 2 Pack

Works perfectly with a Zoom switch. I have an old Zoom switch 10 and when I replaced it with a ZMS 20 I did not get the female headset jack. My old one still works but has some problems. Ordered this two pack and they arrived sooner than expected and are working better than expected.My old headset jack would occasionally create static on calls and did not seem to work as well with Dragon Naturally Speaking. The quality of my writing improved dramatically when I changed to the Onvian headset jack over the one that came with old Zoom switch. My first phone call using this new jack with my old headset was a conference call that included people in India and my call quality was unbelieveably good.

Bought this along with a really nice noise cancelling gaming headset to use for my Polycom VVX501 phone at work. Audio quality on my end sounded great, but on the client side of the phone callers would hear their voice echoing. I work in the tech industry and checked all the phone settings and tested just my headset on my cell phone and did not get the echoing so it had to be this adapter that did not working with my Polycom phone. Was hesitant at first when only the name Polycom was in supported brands and no model numbers listed.

These two are both high quality. The connectors are small and snap together perfectly. I am able to use my 50-ohm Sennheiser G4ME Zero Headset to make phone calls from the headset port in from my VoIP desk phone at work.The pack of 1 was 6.99 and the pack of 2 was 7.99. It was a no-brainer to get the 2 pack even if I didn't immediately need both. I'll let my co-worker use the other one after he gets jealous enough.

Great way to repurpose and use any headphone with mic that generally have 3.5mm connections with standard telephone. Makes any telephone hands free. No need for expensive headset made specifically for just telephones

Very misleading description. This adapter splits the input (headphone function) and output (microphone function) into 2 separate 3.5mm jacks. I have no idea what this could possibly be useful for. But it was useless for me b/c it only allows you to hear the caller, but does not allow you to be heard by the caller (unless, presumably, you have a separate microphone plugged in to the mic jack?).

Was trying to find a way to hook up a wireless headset to a telemarketing phone...... Didn't work!

These would be a lot better if you could plug in a secondary power source so you didn't loose the sound quality/volume. These tend to make you sound distant or faded.

Onvian RJ9 Male to 2 3.5mm Female Headset Phone MIC Audio Splitter Adapter Cable 2 Pack

This cable is not a splitter for 2 headsets. It splits output from input into two separate 3.5 mm female jacks.In the end it is useless for what I ordered it for.

Good quality. I use it to connect my computer headset to my landline phone.It works as it should.

Good

They don’t work tried on several head sets you can hear just can’t be heard.
