Fiio FiiO BTR13
FiiO BTR13 is a compact rechargeable Bluetooth receiver, USB DAC and headphone amplifier designed to add wireless playback and digital audio to wired earphones and headphones. Its physical BT/PC/PHONE switch changes both the connection method and power behaviour without requiring menu navigation. Dual CS43131 DACs, 3.5mm single-ended and 4.4mm balanced outputs, global PEQ and a colour display make it the entry-level all-rounder in FIIO’s BTR range. It is best matched with IEMs and portable headphones rather than very demanding full-size models. Why it stands out Bluetooth receiver and USB DAC in one pocket device Receive SBC, AAC, aptX, aptX Low Latency, aptX HD, aptX Adaptive or LDAC from compatible Bluetooth sources, or connect by USB-C for driver-free PCM playback up to 96kHz/24-bit. Physical BT, PC and PHONE mode switch BT mode receives wireless audio, PC mode uses USB audio and USB power, and PHONE mode uses USB audio while normally preventing the BTR13 from drawing charging power from the phone. Dual outputs with useful portable power The 3.5mm output provides up to 100mW + 100mW at 32Ω, while the 4.4mm balanced output reaches up to 220mW + 220mW for compatible earphones and headphones. Global PEQ, colour display and CTIA controls The 0.96-inch colour screen shows operating information, while FIIO Control and compatible web control provide PEQ adjustment. The 3.5mm socket also supports compatible CTIA in-line controls and microphones. Best for Using wired IEMs or portable headphones wirelessly with a phone Switching between Bluetooth, phone USB audio and computer USB audio Listeners who want 3.5mm and 4.4mm outputs in a lightweight clip-on device Users who want PEQ without buying a higher-priced BTR model Not ideal for Very demanding full-size headphones that need higher sustained power Users requiring high-resolution USB decoding above 96kHz/24-bit or native DSD Systems requiring dedicated RCA, XLR or fixed-level line outputs Sending Bluetooth audio to wireless headphones or speakers EMiUZEK Buying Notes BTR13 is a Bluetooth receiver, not a Bluetooth transmitter. It makes wired headphones wireless from the source side but cannot send audio to Bluetooth headphones. The included cable is USB-C to USB-C. Lightning iPhones require a separately purchased compatible USB-C-to-Lightning data cable for wired USB audio. The highest quoted power is available from the 4.4mm balanced output at 32Ω. Choose BTR15 or BTR17 when more power or higher USB decoding capability is required. The back clip is built into the body and is not a removable protective case. A lanyard is included, but a protective case is not listed in the standard package. FAQ Should I buy BTR13 or BTR15? Choose BTR13 when low weight, lower cost, Bluetooth, PEQ and enough power for most IEMs or portable headphones are the priorities. BTR15 adds a dedicated XMOS USB controller, supports up to PCM 384kHz/32-bit and DSD256, and provides more balanced power at 32Ω. Both support 3.5mm and 4.4mm headphones, so BTR15 is mainly the better choice for higher USB capability and additional power—not simply because it is newer. Can BTR13 transmit Bluetooth audio to wireless headphones? No. It receives Bluetooth audio from a phone, tablet or computer and plays it through wired headphones connected to the 3.5mm or 4.4mm output. It cannot act as a Bluetooth transmitter. What is the difference between BT, PC and PHONE modes? BT mode is for wireless reception. PC mode receives USB audio and takes power from the USB connection. PHONE mode receives USB audio but normally disables USB charging so the BTR13 uses its own battery and reduces the drain on the phone. If the battery becomes critically low while powered off, forced charging can still occur. Does wired USB provide higher resolution than Bluetooth? USB supports driver-free PCM playback up to 96kHz/24-bit. It can avoid Bluetooth codec compression, but BTR13 does not support the 384kHz/32-bit and DSD256 USB capability of BTR15. The audible result still depends on the source file, playback software and headphones. Can I use BTR13 with an iPhone? Bluetooth works with iPhone through AAC. For wired USB audio, USB-C iPhones can use a compatible USB-C data cable; Lightning iPhones require a separately purchased compatible USB-C-to-Lightning data cable. The included cable is USB-C to USB-C. Will the microphone and buttons on my headphone cable work? The 3.5mm output supports compatible CTIA in-line controls and microphones. This does not apply to ordinary 4.4mm balanced headphone cables, which normally carry audio only. Compatibility can vary with the cable wiring and connected phone or application. Can BTR13 connect to two phones at the same time? Yes, it supports Bluetooth multipoint pairing with two devices. Only one device supplies audio at a time; pause the first source before starting playback on the second if switching does not occur automatically. Should I use the 3.5mm or 4.4mm output? Use 3.5mm for standard headphone cables, CTIA headsets and lower power needs. Use 4.4mm only with a headphone cable wired for balanced operation when more output power is useful. Do not convert a 4.4mm balanced output to a single-ended headphone with an unsafe adapter. Can it drive full-size planar or high-impedance headphones? It can drive some efficient full-size models, but its 220mW + 220mW balanced rating at 32Ω is intended for portable use. Very insensitive planar headphones, high-impedance models requiring substantial voltage or listeners needing large volume headroom should consider BTR15, BTR17 or a desktop amplifier. Does PEQ work with Bluetooth and USB? FIIO lists 10-band PEQ and GEQ support across Bluetooth codecs and USB Audio. Settings can be managed through supported FIIO Control functions or compatible desktop web control. The web controller requires a supported browser and desktop operating system. How long does the battery last? FIIO rates battery life at about eight hours, with charging taking up to approximately two hours. Actual runtime changes with codec, output connection, volume, headphone load, screen use and PEQ settings. Can I connect BTR13 to active speakers or a car AUX input? A 3.5mm connection can feed a compatible AUX input, but BTR13 does not have a dedicated fixed-level RCA or XLR line output. Begin with low volume and adjust carefully. Car mode can coordinate power behaviour with a compatible vehicle USB connection.
