Howdy!
The Micro Strap Extension was designed for the portable-application [dual 9v battery-powered] HeadRoom Micro Amp & Micro DAC ("The Micro Stack") separates which have been officially discontinued. However, we'll be happy to make you one as a 'special-order' upon request if you'd like! (...er, please allow as much as 4-8 weeks for delivery depending on our sewing/fabric dept schedule

Just shoot me an e-mail over at

Cheers,
