When it comes to headphones, not all are suitable for bass instruments. Many may sound good for music but plug them into the headphone jack of a bass amp and you will soon find their limitations. PJB H-850 headphones are a result of years of auditioning headphones for this purpose and analysing the mechanisms of what works for the reproduction of music and bass. Utilising high power 40mm neodymium magnets and closed back acoustic loading, we were able to achieve a superb sound reproduction for both music and bass instruments.

These headphones are lightweight and therefore can be worn for hours with comfort. They have superb acoustic isolation from external noise and headphone bleed through for recording application. After you try the H-850 you will soon realise these will be your favourite headphones.

Bighead Pro (HA-2)

Mobile High Performance Multi-Function Headphone Amplifier/Digital Audio Interface

The HA-2 is the second model in the Bighead series and is a step up model of the popular HA-1 Bighead with added technology and features. The HA-2 is a high resolution USB audio interface that supports PCM playback with up to 384 KHz sample rate/24 bit resolution. On DSD playback, sample rates of 2.822MHz and 5.644 MHz are supported, making it the ideal choice for musicians and engineers that desire high performance and the purest sound quality.

It is a rechargeable lithium ion dynamo that is ideal for use in practice or recording situations. It also functions as a headphone booster amp as well as a preamp to drive powered amplifiers. The HA-2 has both passive and active instrument inputs with a 2 band EQ that is ideal for guitar and bass, yet versatile enough for use with other instruments.

It has an internal lithium-ion rechargeable battery that is fed by its USB jack, so any computer or appropriate cell phone charger can charge it in less than 3 hours, but it can play for up to 8 hours.

If you have a big head or not, you will love the PJB BigHead!

BigHead

HA-1 Mobile Headphone Amp with D/A converter

The PJB BigHead is not big at all. In fact it is barely larger than an iPhone. The “Big” is about the sound. It functions first as an awesome bass headphone amplifier with 2 band EQ ( +/- 18db @ 60 Hz and +/- 18dB @ 5KHz) set for optimization of all kinds of bass instruments.

Unlike consumer electronic MP3 players and smart phones that have very small power output of around 20 milli-watt to drive headphones, the BigHead has more than 10 times the power. This contributes to a far more exhilarating listening experience with increased resolution and dynamics. Even if you are just listening to music, the BigHead will be a great improvement to your regular headphones, adding more listening pleasure.

A more important function of the BigHead is being a recording tool both in digital and analog. As an Analog Digital Converter, it has the finest BURR BROWN digital components. The USB out is 48KHz 16Bit digital conversion. In other words, recording your bass onto Pro Tools will give you exactly what you wish for and absolutely nothing else.

Maybe you need an analog pre amp. The Big Head can do that too. It will provide up to 12dB of gain and better than 96dB signal to noise ratio. Just use the headphone out jack to feed an amp or mixer. It has an internal lithium-ion rechargeable battery that is fed by its USB jack, so any computer or appropriate cell phone charger can charge it in less than 3 hours, but it can play for up to 8 hours.
