Question: I have a headset that I use on my line phone.  I can transmit (speak) and receive.  The cable is only 4 feet long and I need at least 6 feet.  Will this cable allow me to transmit (speak) AND receive?
Document: I got this item as an extension for my inline microphone and headset for my iphone. It does not work. I can't use it for recording videos with my phone as I'd hoped.Very disappointedIt has the 4 connections on the male end, but who knows what's inside the female end, you cannot see, but I suspect it only has the 3 connection points of a normal micless stereo headset
I had ordered the iHip - Noise Isolation Pro DJ Quality Headphone but unfortunately the cord was so short that I had to practically sit on top of my stereo while using the headphones. I purchased this StarTech Headset Extension Cable to make it possible for me to sit a couple feet from the stereo. I think the original headphones should have come with a 6 ft or so cord, but now that I have this extention it works great. I would recommend it to anyone wanting to extend their distance from stereo to headphone.
Works great with my HTC One! I use this in combination with a Right Angle TRRS adapter to keep from yanking my phone off my desk whenever I think I see a squirrel outside. Audio quality is great - I don't notice a difference between being directly plugged in and using this cable. I don't remember if it works with the button on my headset, but then again, I don't really care, as the phone is right in my face on my desk.
Pros:- Works with virtually all Apple products (tested on iPhone 5s, iPad 2, MacBook Pro).- Works plugged end-to-end into each other.- Best price I could find on the net.- Fantastic length (approx 6 feet per cable).Cons:- It give horrendous messages.
I have just been having great luck with cables on Amazon lately. I bought an assembly of cables not too long ago and they were all broken or disfunctional in some manner, but I lucked out this time. This 4-pin 3.55mm extension cable works great and does not lose the input or the output at all through the extension process.
I purchased this extension cable primarily to allow me to use my iPhone headphones as a computer headset for Skype and similar services (I have a Lenova Thinkpad with an integrated headphone/mic jack). It works perfectly for that purpose. However, when connected to my iPhone 4S, the advanced features (volume, play/pause, etc.) do not function. This doesn't cause a problem on my PC, however, as those features never work there.
this headset extension allows me to use my headset to answer the phone as well to activated my music app on my android phone oh just in case 2m=2feet..
what can you say about a cable except that it works great with my RODE Smartlav. You really need this cable if you use the Smartlav.
this works exactly the for what i wanted. it works with my iphone ear pods...which i connect to my imac. without the 4 position TRRS, you can't use them. the fourth position is for the microphone. this would work with any headset/headphones with a built-in mic.
I broke my first cable--it was my fault--and this is my second of the same brand. I use it on my motorcycle with headphones attached to my gps. It is long enough so that I can steer without interference and I can even wind it into my pocket (there's extra). As far as music, the quality loses nothing in the translation.
Answer: Yes a 4 position is an extension for standard headset. It allows stereo and mic function. This is what ur looking for.
