Good connection and good sound quality. Battery life is okay given it's size. Good connection and good sound quality. Battery life is okay given it's size.

It's great, this device enables me to listen to music on my 15-year old iPod Classic (on its second battery) while walking outside without having to bother with trailing cords blowing off earpieces in a Wellington breeze. Quite a challenge to connect the device transmitter to JayLab Go Sport+ wireless earbuds, but I got there in the end...

Does exactly what it says on the tin, plugged into an "old school" Altec Lansing boombox :) My review title says it all -just buy one! Outstanding for the $$s... nice one PB Tech. 10/10 Does exactly what it says on the tin, plugged into an "old school" Altec Lansing boombox :) My review title says it all -just buy one!

It works well, but the only problem with it it reconnects after you have disconnected it, it is a pain when you forget it does it and go answer a call.

Wouldn't pair with my Edifier speakers whatever I tried. Wouldn't pair with my Edifier speakers whatever I tried.

Quite a niche product, but very handy in my particular use case. Set up and pairing was very straightforward and sound quality is great. Quite a niche product, but very handy in my particular use case. Set up and pairing was very straightforward and sound quality is great.

Great little dongle to convert a 3.5mm port to a bluetooth receiver. I use this in my car as my stereo is not bluetooth and it works great. Lasts for 8-10 hours on a charge at least.
Slightly large for being plugged into my car, but seems to stay in okay and is well built.
I find the 3s delay to turn it on/off a little annoying - would prefer a switch, but really not a major. Great little dongle to convert a 3.5mm port to a bluetooth receiver. I use this in my car as my stereo is not bluetooth and it works great. Lasts for 8-10 hours on a charge at least.

This device is very limited when it comes to interacting with other devices. I would suggest to only use this with "dumb" devices like a pair of speakers etc however a google chrome (audio) would be a better choice.
