The wis instruction system powered by equiteacher has been on the market for some years now.
Meanwhile, it has proven that it was a good alternative to the expensive sennheiser and senrun instruction systems which until 2012 were the only instruction systems that were available and that worked a bit decently.
The systems of sennheiser and senrun were many times more expensive (sennheiser around 1000 euros and senrun round 500 euros) and many found that just too much money for an instructionsystem.
With the arrival of equiteacher systems, the price went below € 200 and the systems actually worked better than the expensive systems.
The range was bigger, the sound was just good and the price made the systems popular.
