Question 1

is the cord for this headset braided by chance? or normal rubber coating?

Accepted Answer

The cord has a normal rubber coating.  I have bought this specific headset a couple of times over the years because of its durability and toughness (I have a very BIG head), but the cord is the weakest link in the design.  On the up side, the cord is very long (8 feet).  This can help with cord routing away from pinch points to help avoid damage to the cord.  I recommend it.

Question 2

does this head set have 2 plugins?

Accepted Answer

This headset has a black 3.5 mm connector for audio and a grey 3.5 mm connector for the microphone. They are separate.

Question 3

Does this headset have inline volume and mute controls?

Accepted Answer

No and the pair I received, the plug ins were wired backwards....the green was the Mic and the red was the speakers.

Question 4

does  the koss sb45 headset need phantom power?

Accepted Answer

I just use it with my HF transceiver and it is just plug and play.  No additional power necessary.

Question 5

Does this head set work with mini-jack phone inputs?

Accepted Answer

It has standard 3.5mm jacks that fit directly into a regular PC sound card.

You will need an adapter if by 'mini' you mean a 2.5mm jack like some cell phones have.

Question 6

Where are these headphones manufactured?

Accepted Answer

I don't know, but they are awesome. I'm on my second pair in 10 years.

Question 7

Would this fit a child's head?  Is the microphone adjustable?  Are they sturdy enough to survive a ten year old?  Thanks in advance for any info!

Accepted Answer

This unit might be a bit large for a child. As an adult man, they fit me fine with room to spare. The microphone rotates up and down, but you cannot adjust the length, nor is it the type you can bend into various shapes. The unit is very sturdy, it has survived numerous drops and bangs. The only issues you'll likely have is that the spit guard will come off the mic and the padding on the ears will eventually rub off, shedding black flakes. That's only after a year+ of daily use though.

Question 8

What type of cord plug in is used on this headset?

Accepted Answer

Two standard 3.5mm jacks, one for Mic and one for Audio. It can plug directly in to a standard PC sound card.
