A few general FACTS about earpieces…

Every earpieces should:

  • be as small as possible, but not too small because it can sink into the ear channel and you will have to call 911
  • have perfect anatomic shape, that fits inside the ear channel
  • have good sound quality, allowing you to hear your assistance colleague very clearly, without any effort. On the other hand sound should not be very loud so the teacher will not be able to hear it
  • the range between the loopset (hands-free)and the earpiece should be no more than 50cm because if someone else in the classroom also has it, the interference will be terrible

 

Earpieces based on the BLUETOOTH technology? No.  Why?
All the earpieces are based on inductive technology, by transforming vibration from loop ( hands free, watch, pen or similar) to sound ( voice).

So, why all the sellers recommend Bluetooth earpiece then?
It is a marketing matter, in fact hands free or similar equipment has Bluetooth, but not the earpieces.

One of the frequent questions is: why does your earpiece have a BLACK top?
Well, think about this: what is the color of the hole in your ear channel? Have a look on someone’s ear inside. The color you will see is either BROWN or BLACK?
It is BLACK. We can paint the tops into brown, but it will be a failure. Guaranteed.
