I've actually bought 3 of these recently. One for myself and 2 for presents for my daughters.
There's a lot to like about this product. But firstly I want to get the negative out of the way. The headset will not delivery any decent base sound. For earphones they just don't cut it at all.
But the Clip-on bluetooth device is outstanding. Put a decent pair of headphones or earphones on it(without microphone) and you've got a great arrangement for hands free listening to your Tablet or phone. The mic on this is a great quality and everyone who I speak to using it says they can't hear the difference to my LG G4 phone, which is a pretty outstanding phone.
The C-clip that you add on to secure the earphones works on most other earphones. I'm using a permanent pair of earphones [ Betron B650 Noise Isolating Earphones Headphones, Powerful Bass (Gold)]] that are awesome with this device.
I'm also using the i6 to listen to my TV and my Amazon Fire TV. I'm using a splitter for two headphones. For the TV I've used an array of products to link the optical sound out, convert with a lindy audio converter, a long extension headphone cable into a bluetooth receiver Bluetooth Transmitter, TaoTronics Portable Wireless Stereo Music Transmitter for 3.5mm Audio Devices: TV, PC, Tablet, MP3/MP4, iPod and other Media Players
It all sounds complicated but at the end of the day we are getting tremendous sound out of this little i6 device for our TV use. Once the Lindy box is connected to the optical output from the TV you can pick up the linking in SKY TV and BLUERAY/DVD Player.
The hands free really works a treat. Saving you from risking a drop of your phone.
I also use this device for running and the gym as well. Linking it to my phone. But I was offered another bluetooth device all in one to try which is working well too directly from my phone(for running. Using headphones for the gym).
However, the i6 enables you to put earphones or headphones to it. The delivery of bass is really great. The TV experience has transformed to what it really should be now.
