I own a Samsung Galaxy S3 and the connection to the device works without problems.
In brief, I'm going to buy a second for my work.
I can recommend it to anyone. I am very pleased.
A small point deduction, there are however yet.
Sometimes the connection is something hakelig so sometimes interruptions are audibly.
At the reach kanns not lie because smartphone and the Speaker max. Are 1 meter away.
Even the approach of bringing benefits then nothing. Here's the question: Liegts the smartphone or on the device.
Since I do not know I can deduct any point for the device.
Despite everything, I use this device very often and am only now and then appear happy despite the interruptions.
