As a group of audiophiles, we repeatedly tested XROUND on numerous sound sources — including movies, video games and streaming music — for a very long time to ensure it achieves the highest sound quality.

To support better hearing for users, we designed XPUMP — a user-friendly audio booster that supports all speaker and headphone types. The thumb-sized XPUMP, which embeds XROUND technology, revolutionizes the audio industry.

With XPUMP, users could feel the sound is coming from outside the speakers or a headphone and being embraced by the sound field. The angle of sound field expansion can be up to 300% of regular stereo.

XPUMP is capable of real-timely boosting the detail in every soundtrack to give people vicarious pleasure that they could only experience in a live concert, show, a theater, or a recording studio. The powerful audio algorithm is running on the dedicated dual core processor at the clock speed of 55.3 MHz, which automatically proceed and transform the melody every microsecond.

XPUMP features 8hrs+ battery life.

XPUMP can be connected between the audio source and your passive speaker amplifier

XPUMP is warrantied for one year

If your Bluetooth headphone has a 3.5 mm audio jack, XPUMP should work well.

Otherwise, you will need to add an extra Bluetooth transmitter to pair with it.

Bluetooth speakers such as Bose Soundlink mini and Jambox all work well with XPUMP as both of them have the most common 3.5 mm audio input.

We have tried XPUMP with some popular speakers such as: Audio Engine A2, Bose soundlink mini, Jawbone Jambox, FOSTEX PM0.3, Altec Lansing VS3020/ VS2720, Edifier Luna Eclipse and harman/kardon SoundSticks III 2.1.

They all work together very well and match well with each other. XPUMP also works well with PS4 if you just add an optical-to-analog converter.

We also think XPUMP can also work with your 5.1/7.1 sound system although you might already be very satisfied with your original setting. As for headphones, we think theoretically any wired headphone can work with XPUMP.

Please let us know what kind of stereo speakers, sound bars or headphones you want to match XPUMP with. And our engineering team would get back to you very soon.

We believe XPUMP can also work in your car sound system. And just to share with you that we have tried XPUMP with BMW Z4 and Lexus SUV, and XROUND DSP effect is enormous in those vehicles.

XPUMP is a smart audio processor, and not a dac, nor an amplifier or an equalizer. But XPUMP can work with your original amplifier or equalizer or without them.
