Fiio BTR11 Portable Bluetooth Headphone Amp

The FiiO BTR11 is the simplest, most affordable way to make wired earphones wireless without giving up sound quality. This thumb sized Bluetooth receiver adds LDAC high resolution streaming, a built in microphone for calls and up to 15 hours of battery life for less than the cost of most replacement cables.

Type and Technology

The BTR11 is an entry level portable Bluetooth receiver and headphone amplifier built on the BES2700 chipset with Bluetooth 5.3. It supports LDAC, AAC and SBC codecs and feeds a clean single ended amplifier stage through its 3.5mm output.

Sound Character

For a device this small and inexpensive, the BTR11 sounds impressively clean and lively, with LDAC preserving detail that ordinary Bluetooth adapters smear over. Its 30mW output at 32 ohms happily drives IEMs and efficient portable headphones.

Build and Features

A dual color LED communicates status and active codec, while physical buttons handle volume, playback and calls through the built in noise reducing microphone. It weighs about 13g, clips along at 55mm long, charges over USB-C, and reaches roughly 15 hours of playback on AAC or 8.5 hours on LDAC.

Best For

Commuters, gym sessions and anyone who wants to keep using beloved wired earphones with a modern phone. It is the perfect budget companion to picks from our IEM collection; see the whole range in the portable DAC/Amps collection and more from the brand in the FiiO collection.
