Description
There are a lot of headphones and earphones. BPP (batpure-portable) demonstrates the effect in almost of all those equipments. In case of headphones, we generally listen to music by ear though, BPP provides supersonic wave which is contained in startup sound via face skin! 
TakeT BPP is not only for portable players, but also effects to the high-end class headphone systems with amplifiers.
The order of highly effection: High-end headphone > general headphone > high-end earphone > general earphone.
How to use BPP for portable music players.
Insert a splitter into an phone jack of the music player.
Connect BPP and the an earphone(headphone) plug with a splitter by parallel.
While listening to music by earphones, BATPURE radiator of BPP turns to the direction of your face.
The effect is demonstrated even if the distance is around 5m away when the radiator of BPP is in the direction of your face even a little.
In case of TV watching, BPP and earphones(headphones) connect with TV's phone jack via the splitter by parallel.
Please add and use stereo standard plug /stereo mini-jack's conversion adaptor in electronic musical instruments etc. of the standard size specification.

Review
excellent very happy!!Other items of note
Entranced sound' effect is easily added only by connecting BPP with the headphone or earphone in parallel, then it approaches to genuine live sound.Exception an old MD player (ATRACK1 recording) does not achieve 'Entranced sound' effect. There is a possibility of the influence that the frequency of 15kHz or more is cut with the filter in the ATRACK1 recording, Ipod etc. of the AAC recording are achieved an enough effect.
