Summer is here and July’s product reviews are mostly devoted to audio tech.

Helm DB12 Mobile Amplifier

I am excited to review two advanced audio quality boosting gadgets for mobile devices this month. The first of these addresses a key issue all smartphone or tablet users will have faced when trying to play music, movies, or podcasts over high-quality headphones or external speakers, volume. No smart device can output the sheer loudness of a separate Hi-Fi or dedicated media center amplifier meaning if you want to watch films or listen to high-quality music with friends you inevitably have to compromise on sound quality and volume.

The new HELM DB12 AAAMP Mobile Headphone Amplifier addresses the low-level volume our portable devices output, providing a 12-decibel gain boost plus an optional 6-decibel bass boost. This boost in gain is vital for power-hungry headphones like planar magnetic or high-impedance types, ensuring you hear the best quality sound and it also makes sure plugging your device into a portable battery-powered speaker or mini Hi-Fi gives you sound levels that will fill a room at a party or in a shared movie screening.
