Bluetooth audio brings new life to your traditional amplifiers, which are no longer restricted by cables. With Bluetooth you can make yourself comfortable on your sofa or armchair and have full control over your sound without having to move. Once you've experienced the convenience of Bluetooth, you'll find it hard to go back to wired listening. The FiiO BR13 offers more support for various Bluetooth codecs than other products in its class and supports seven hi-res Bluetooth codecs, including LDAC. With LDAC, you will experience stable, high bit rate sound comparable to CDs. The FiiO BR13 has a wide range of digital and analog outputs for greater compatibility with other devices. The FiiO BR13 has a special high-contrast and durable VA display that allows you to see codec, EQ and other information at a glance. Unlike many other products in its class, the BR13 can be controlled either via buttons or via a dedicated app. Whether you approach the device to operate the buttons or lie down on the sofa with the companion app, the BR13 is easy to control. The BR13 has seven presets, including pop and classical, allowing you to enjoy different genres of music instantly. You can also configure two types of parametric EQ - with 10 customizable frequency bands, each with an adjustable frequency, level and Q bandwidth. Tweak them to your heart's content to find exactly the sound you're looking for. Unique to the BR13 is the ability to upsample low sample rate audio signals to high sample rates of up to 96kHz/24bit, via any input, bringing you even closer to master level sound quality. The BR13 offers Bluetooth, USB and SPDIF functionality in one device, so you can use it conveniently with different audio devices. Bluetooth: Compatible with cell phones, tablets, laptops, TVs and other devices with Bluetooth transmission.
