Bluetooth Case for Sony MZ-510/MZ-NF610 MiniDisc Player

Introduction

I love my MiniDisc player, but unfortunately, I am spoiled by wireless headsets! I decided to remix a cradle for my Sony MZ-NF610 and turn it into a case that holds some commercial-off-the-shelf parts to add Bluetooth functionality, while retaining 3.5mm output.

It's not exactly pocketable anymore, but it can rest on a desk while you walk about, or inside a bag or cargo pants.

• UGREEN Headphone 3.5mm Y-Splitter - (Amazon)
• 3.5mm Audio Cable - Male to Male [0.5 ft] - (Amazon)
• 1x M2 x 6mm Flat Head Screws - (Amazon)

This case works best if you have a charger cable.
