I have a Logitech Z906 speaker system.
The Z906's control console features 3.5mm input and output jacks.
It does not feature Bluetooth, which is what I am wanting.
There's the Logitech Bluetooth Audio Adapter, which is currently £26 on Amazon UK and at Currys PC World.
However, there are many cheaper variants that seem to do the same job on eBay, starting from £2.50. Link to eBay search here.
Should I just go for one of those, instead?
