When students outgrow our K6 primary SchoolPHONES®, they grow directly into our new BK series which will fit students through high school and beyond.

Like our K6 series, the BK series respects the proven foundation of the SchoolPHONES® family of headphones. Every feature >headband material > to age appropriate size > to hypoallergenic one piece foam ear cushions > cable material, length, strength and chew/tangle resistant diameter was inspired by a group of elementary school teachers at Palm Beach Public School more than 20 years ago. BK is the 5th generation in the evolution of quality one to one educational headphones at a cost even a low income household can budget.

This “BKd” model adds “flexibility” to our headphone family.  It features a removeable/ replaceable/upgradable cable assembly. This allows “cost effective” replacement of damaged cables as well as upgrades to future “new” interconnection methods and adaptation for media applications using our unique Springboom™ plug-in media microphone accessory. The Springboom™ microphone is fit with a high sensitivity, uni-directional electret capsule to assure clear voice recording with minimal background noise pollution.
