FiiO BTR13 – pocket Bluetooth DAC amp

FiiO BTR13 gives Soundium listeners a compact way to use wired headphones with phones, laptops, tablets, and car USB audio. It combines Bluetooth 5.1, USB DAC modes, dual CS43131 DACs, 3.5 mm and 4.4 mm headphone outputs, and app adjustable PEQ in a 28.6 g body with an integrated clip.

Key Features

• Three listening modes: Switch between PC, BT, and PHONE modes for computer USB DAC use, Bluetooth receiver use, or phone powered portable DAC listening.
• Dual CS43131 DACs: Each channel is handled by its own Cirrus Logic DAC to reduce crosstalk and keep the presentation clean.
• Balanced headphone drive: Use the 3.5 mm single ended output or the 4.4 mm balanced output, with up to 220 mW + 220 mW into 32 ohms from balanced out.
• High resolution Bluetooth: Qualcomm QCC5125 Bluetooth 5.1 supports SBC, AAC, aptX, aptX LL, aptX Adaptive, aptX HD, and LDAC.
• Global PEQ control: Adjust EQ through the FIIO app or web PEQ, with presets and custom tuning available across Bluetooth and USB DAC use.
• Everyday usability: The 0.96 inch color IPS display, CTIA inline controls, integrated clip, and patented car mode make daily use straightforward.
