Review: A good piece of kit. - An excellent piece of kit. Useful in noisy situations to isolate the sound of one's instrument from the background noises.
Review: Great for tuning in noisy places - This was bought in addition to a CM-300-BK that I have had, and been pleased with, for three years. Apart from the jackplug size and logo the CM-300-BK and CM-400 seem identical. Both have a 30mm jaw capacity and 150cm cable. The 3.5mm mono jack on this model allows it to be used without adapters together with tuning software on a phone, tablet or laptop. It works with my Lenovo Moto and Thinkpad devices with no problem. Another reviewer complained that she could not fit on of these microphones to a bagpipe drone, but I, and other pipers have no problem clipping these onto great highland bagpipe drones and chanters. Their contact mechanism is especially useful in a band environment.

### ⭐⭐⭐⭐⭐ A good piece of kit.
*by G***R on 15 January 2026*

An excellent piece of kit. Useful in noisy situations to isolate the sound of one's instrument from the background noises.

### ⭐⭐⭐⭐⭐ Great for tuning in noisy places
*by R***H on 3 August 2024*

### ⭐⭐⭐⭐ It needs to be longer
*by D***D on 17 September 2025*

Does what it's supposed to do and it does it well, it could be better with a longer lead as I sometimes drag the metronome of the table when I get carried away, you know you get lost in the music then clatter (O I hope i ain't broke it) so a longer lead and it would be great not good hence the 🌟🌟🌟🌟 as for tuning accuracy its not spot on, but i did put it against my peterson strobo, value for money expensive for what it is, sound quality well it dont produce any sound it's for listening so 0 there, ease of use, it could not be any easier plug and play.
