I was talking to my neighbour recently and found that she had bought one of the spare rooms in our basement area and uses it as a piano room.
Otherwise, of course, the noise from our children learning the Piano would disturb our neighbours.
It is so wonderful to live in a country (Switzerland) and in an Apartment block where such care and consideration is made.
Likewise I can say that we too have a gadget that helps reduce noise pollution
[Note: We already don't have any Hi-Fi system, because we don't want to burden our neighbours]
Bluetooth Sound Transmitter
What does it do?
The Black square box takes any audio output and retransmits it as a Bluetooth Audio Source.
SO, then you take your bluetooth headphones, or other Bluetooth receiver and listen to the audio.
In the above, I tested with an Apple iPod (Bluetooth off and output via the lead shown). Audio enters the Bluetooth transmitter and I listen to it on my Logitech H800 headphones.
Did it work?
So far it's a little hit and miss to get the headphones to latch onto the Bluetooth transmitter.
But once connected, it works fine.
What about the Batteries?
The unit contains a rechargeable battery. You charge it via a USB to mini cable. This battery powers the Bluetooth transmitter.
We tested it on a variety of audio devices. At high outputs the transmitted audio became severely distorted. This is a potential issue since some devices (e.g. TV's) might have a fixed level audio out.
Product is average. No better. If I have the time I will purchase a differently design one from eBay to make a comparative test.
