Bonedo 4400 Test

With their first two headphones, the small Japanese manufacturer Phonon from Kawasaki near Tokyo has also attracted attention in Europe. The SMB-02 is a high quality studio headphone with very good bass resolution and neutral transparency. The Phonon 4000 is a very compact and extremely foldable DJ headphone. With the 4400, the Japanese are now presenting an update that is to combine the sound characteristics of their studio headphones with the form factor of the DJ headphones.



DJ Lab review

For our dear German friends, here is a great review (in german) of our “Studiokopfhorer” SMB-02 on the German online electronic music magazine DJ LAB. Danke Schone! Es gibt ja immer wieder Equipment, das auf den ersten Blick für einen Wow-Effekt...

 The decay of my bass drum, tails of my reverb, depth and width of my delays all in an affordable package. The Soundstage felt almost like a speaker setup in a well treated room - surprisingly accurate for closed back headphones. 



MUSICLIFE is the product I always wanted to have. Portable and convenient with the high-quality resolution of a big speaker system.
A one-unit stereo speaker packed with the complete PHONON sound. It’s my sonic bonsai!”

"Isao Kumano: Originally, I had been running my own music studio, maintaining and re-modelling it myself as well as making all the equipment I needed. phonon’s products are an extension of this, and of what we’ve been doing for years in the studio."
