Updates in Fiio BTR5 compared to BTR3 

1. Update from Bluetooth 4.2 to Bluetooth 5.0 

BTR5 with BlueTooth 5.0 offers a more stable connection at twice speed and four times of range of Bluetooth 4.2. This increase in range, plus the ability to transmit audio to two devices, means that people could send audio to multiple rooms in a house, create a stereo effect in one space, or share audio between two sets of headphones. 

2. Update battery capacity from 300mAh to 500mAh

The 300 mAh battery in the BTR3 takes only 1.5 hours to fully charge but the 500mAh battery in BTR5 takes 2 hours using quick charging.  

3. Update DAC chip from AK4376A to Dual ES9218

Comparing with AK4376A DAC in the BTR3,  Dual DAC ES9218  in  BTR5  offers high resolution, clear and powerful output with low output impedance, while being very power efficient. This change not only has the signal-to-noise ratio (SNR) increased, but distortion has also been reduced for greatly improved sound quality. 

4.  Fiio BTR5 Weighs a little more

BTR5 size is 72*32*11.3  while BTR3 size is 58*25*10.4mm. Because of increased battery capacity, the weight of BTR5 is increased to 43.7g from 25g but it is still very convenient to take out.
