The microphone sounds good with my iPhone - if the Hi/Lo switch hidden inside is set to Hi. I haven't had a chance to test the noise-cancelling ability.

This boom mike does exactly what I expected, making my bose headset into a superb tool for long work calls, skype, webex, etc. I wish I had found it sooner. Wish List: Mic Monitoring: I would happily pay more for the addition of 'mic monitoring', like land-line phones have. Land-line phones play you own voice back to you in the earpiece. This helps you modulate your own voice, and (at least to this person who grew up with a land line) make the conversation sound more 'natural'. Mic monitoring is especially important for this product because the bose headset does such a good job of keeping you from hearing your own voice, especially in a noisy environment. Comments on other reviews Heavier wires: would be nice if they spend a couple of pennies more to make it more durable. Mic Boom quality: The mic stays where I want it, with no problems (so far)

Works really great and improved mic audio quality a lot!

I have been a ham radio operator since the 80's, and have always looked for the perfect microphone. I have literally tried hundreds. Some had excellent audio characteristics, but were uncomfortable, heavy or poor audio response. I have several Bose headphones, and my favourite are the QC 15 for listening to music. So, the perfect combination for a headset microphone would ideally be the Bose QC 15 with a boomset microphone element. I didn't know there was an adapter available, until I saw in a recent world radiosport championship video, a group of 4 German girls operating with BOSE QC 15 headphones, with a boom mic element. How was this possible, I thought to myself. After a bit of googling, I came upon this site, and promptly ordered a HeadsetBuddy. It arrived this morning, and I promptly went about testing it out with my QC 15. First was Skype on my MacBook Pro, using Skype test a call. The audio quality was absolutely stunning. I then went to my radio station and hooked the cable up to my Flex-5000 ham radio and 1KW amplifier. After a bit of fiddling with my radio's EQ settings, the transmit audio quality is fantastic !!!! Suffice to say, I no longer need to buy and try anymore headsets or microphones, I have found the perfect solution with the HeadsetBuddy. I will be recommending this product to my ham radio friends around the world, and I will be buying a second one as a backup. The great thing is that it is a multi-purpose solution to lots of cables, microphones, headphones and headsets. With this product I can use one device on my ham radio station, laptop, tablet and smartphone. PS. If you wanted to buy an aircraft Bose headset, they run at around $ 2000.00. With this HeadsetBuddy and an existing QC 15, you achieve the same at a fraction of the price. PPS. I suggest advertising in the QST magazine, the largest ham radio magazine, with about 150 000 ham radio enthusiast subscribers. Thanks for bringing this to the market.

Performs as advertised.

This boom mic provides excellent audio and noise cancellation but is unfortunately let down in two important areas: (a) The arm is extremely soft, thereby constantly drifting downward due to gravity and needing readjustment, and (b) It's impossible to tell the "front" from the "back" (noise cancelling part) of the microphone, thus requiring fiddling each time the headset is used Considering the high build quality of the QC15 headphones, I expected much better quality of such an accessory (and would gladly pay more for it if required)
