FiiO BT11 Review – Design and Functionality
FiiO offers the BT11 in elegant black and silver finishes to match your style and devices. This transmitter is a lightweight dongle with a USB-C port, enabling reliable, lag-free connectivity. As a result, you can enjoy enhanced audio from your wireless headphones and speakers.
The BT11 is compatible with the iPhone 15 and 16 series. It will also work with older iPhones, but these require a Lightning adapter. The transmitter also supports other devices with a USB-C port.
While writing this FiiO BT11 Review, we saw it features an LED indicator that emits differently coloured lights. These shades help you determine which Bluetooth codec is in use.
The LED pulses white when playing LDAC and turns yellow when playing aptX HD. If it shifts to green, it shows that aptX Lossless is playing.
It supports two device connections simultaneously, which is highly convenient. In addition, it acts as a wireless audio splitter to let you share audio with a friend or family member.
Key Features of the FiiO BT11
How does this Bluetooth transmitter deliver high-quality audio to different devices, headphones, and speakers? Our FiiO BT11 Review will discuss its primary features to learn more about its technologies and unique elements.
LDAC Enabled After Four Years of Development
After FiiO released the BTA30 Pro, the company worked continuously to enable LDAC on more devices. Numerous challenges were present, including the lack of original manufacturer support and high costs. After four years, FiiO successfully achieved this goal.
Unlike the CSR8675, the BTB11 supports LDAC transmission, delivering higher computational power while using the next-generation LE audio. The transmitter also supports aptX Lossless. Combining these features creates a high-end wireless Bluetooth audio experience with excellent sound quality.
Tiny Body, Large Core
The BT11 is a tiny, lightweight Bluetooth transmitter weighing only around 3g. It uses QCC51581, the flagship Qualcomm chip. It uses a quad-core processor and two 240MHz Qualcomm Kalimba audio DSPs to deliver superior computing capabilities. As a result, it can work with advanced tasks and various audio algorithms.
The BT11 also supports Snapdragon Sound to deliver immersive audio with seamless and stable connectivity.
Plug-and-Play Lossless Audio for Your iPhone and Gaming Consoles
