I've set this shop up to pass on a few slightly obscure but cunning items I can't find anywhere else.  I'll test that they actually work and I'll try to have one at hand.

They're sent directly from China.  You may be liable for import charges, depending on your country's laws.  UK VAT is collected on all UK sales- prices shown are inclusive and it'll appear at checkout.

I've found that shipping to the UK usually takes between 1 and 2 weeks

There are also quite a lot of variations of devices and software these can work with.  If in doubt I can offer advice, please email rt@rtsound.net
Also please let me know if they do or don't work with specific devices and I can update information.
