Description

• The FiiO BTR15 is a next-generation portable Bluetooth DAC/Amp built as an upgraded evolution of the BTR5 series, delivering higher performance in a lighter and more refined design. It features a powerful dual-core architecture combining the Qualcomm QCC5125 Bluetooth chipset with the XMOS XU316 USB processor, ensuring stable wireless transmission and high-resolution USB decoding performance. The device supports full MQA decoding and handles high-resolution audio up to PCM 384kHz and DSD256 in USB DAC mode.
• Equipped with dual ESS ES9219MQ DAC chips, the BTR15 delivers clean, detailed, and dynamic sound reproduction. It includes global professional-grade parametric EQ (PEQ) tuning, allowing precise sound customization across different usage modes. The independent amplifier power supply design ensures cleaner output with improved driving capability for both sensitive IEMs and more demanding headphones.
• The BTR15 provides both 3.5mm single-ended and 4.4mm balanced outputs, offering flexibility and higher output power for balanced connections. A convenient one-touch mode switch allows seamless transition between PC mode (USB DAC powered by computer), Bluetooth mode (wireless operation with internal battery), and Phone mode (USB DAC powered by its own battery).
• Designed with a 0.96-inch OLED display for clear status monitoring, the device features dual curved glass panels and a premium aluminum alloy frame, giving it a sleek yet durable build. It also incorporates an advanced battery protection system for safe and stable long-term use, with up to around 8 hours of playback depending on usage.
