The difference between B4 vs B4-X: 1, B4-X is a dual mono balanced version. Its channels get amplified by independent components, with power, tubes, and op amp all independent and symmetric, resulting in higher sound separation compared to B4. 2, B4-X uses 2 groups of independent power supply sources (+12V and, -12V) for two op amps, ensuring less mutual interference and can drive 300Ω headphones. Thirdly, The circuit adopts two op amp parallel output, providing better output power. 4, B4-X includes a 3.5mm & 2.5mm output interfaces, ideal for most balanced and standard headphones. Small size and unique design: built-in tube makes you with an amplifier which is held by one hand, making it convenient to carry so you can enjoy HiFi music everywhere. Rich, delicate and soft sound: warmer than transistors, with separate op amp & power supply boosting the SNR & sound separation, leading to higher sound quality. Featuring built-in battery protection circuit: the battery lets your listening feast without time limitation. It can’t be turned on while charging and will shut down automatically once fully charged, and the charging LED will turn to green. High-end materials and construction: featuring gold-plated connectors, original Nichicon electrolytic capacitor, original DALE resistors with precision ring resistance. Prompt and courteous support.
