We were recently featured in the New York Times and Good Morning America! Check out both stories in our news section!



Noise Isolation

The first feature necessary to allow the 85-decibel-limit to succeed is the ambient noise reduction of the BT2200 headphones. Our headphones block out more external noise thanks to multi-layer construction and marshmallow-soft earpads that give a great seal.  By rejecting more outside noise, there’s less need to crank up the volume, which gives the user the greater signal-to-noise ratio needed to understand the audio clearly. 

Puro Balanced Response Curve

The second important feature in limiting the output of headphones is the Puro Balanced Response curve.  The sound curve is based on the work of a research scientist with a PhD in acoustics, Sean Olive. By implementing a flat frequency response curve, mimicking speakers in an acoustically tuned listening room, we bring you audio the way it was intended to be heard – with minimal distortion. (which leads into being able to hear crisp vocals at lower volume levels)

Volume Limiting

Last but not least, our headphones use an advanced signal processor to naturally limit the volume to 85 decibels in either Bluetooth wireless or wired connections. When you’re using them in Bluetooth wireless mode, this level is achieved through a sophisticated DSP (Digital Signal Processor) engine performing Dynamic Range Control (DRC). When used with a supplied cable, there is a limiter in the cable. 85 decibels has shown to be a safe listening level for long periods of time.

Whether Puro products are used as a tool to augment classroom instruction or as an important tool in multi-media rooms or computer labs, and on into home use – Puro’s audio quality can deliver a proven technological approach to improving an individual, group or classroom’s ability to understand the lesson being taught. 

Combine this science with our trident of technology and you have the perfect headphone solution for today’s kids and classrooms.

  Young children are ineffective at deciphering speech in noisy environments until they reach adolescence
•  Children are especially susceptible to ear infections (Otis media) in which middle-ear fluid causes hearing loss for weeks or months following an infection.
  Many children (up to 20%) have some form of hearing loss, with that number increasing as a result of NIHL.
•  For many children, English is not a native language.  Vocal clarity becomes even more important.
•  Many children have some degree of auditory attention and learning disabilities, even though they have normal hearing sensitivity and are learning in their native language. Sound quality and vocal clarity over background noise becomes even more important to keep their attention focused.
