“The T2 plug-system has brought our products to a new level. Previously, the small models had a fixed cable because all previously available plugs were too large. Only with this small and reliable system was it possible for us to equip all our products with the same plug system. The new DS version brings yet another significant improvement. It is a real pleasure!” –– HEAROS In Ears

“We prefer the T2 connector system because the number of repairs relating to the T2 interface is nothing compared to other connector systems” –– Onkyo
