Yep, I'll vote for the SoundPeats too, they work well. They were about $35 on Amazon but they say they are now currently unavailable on the link I last used.
I ended up using the Avantree AS70 as it has an attachment clip and also volume control. Volume will be unnecessary for you though as you have the SPO1 for that. SoundPeats are cheaper and the audio quality was good.
There is a bit of a thread here if you wanted to read some more. Stay clear of the TaoTronics as even though they say they are Low Latency, that is only in Sender mode, not in Receiver.
