FiiO, a china based brand famous worldwide for their powerful DAP's, amazing sounding IEM's and other audio products, they have released the latest iteration of their portable Bluetooth amplifier, the BTR series.
The FiiO BTR5 comes equipped with dual DAC setup, featuring two powerful sabre DAC's ES9218P, which reproduces sound precisely and neatly.
Dual DAC's working together gives out a powerful output of 220mW at 32ohms load and 7.6Vpp at 300 ohms.
The DAC's ensure that there is no noise in your music and the sound output is amplified properly with great power.
The BTR 5 has two slots for your headphones, one 3.5mm single-ended and one 2.5mm balanced output ports, where each channel is driven separately from the other with its own DAC and amplifier.
Both the headphone slots give purer clearer sound experience with ultimate details.
The BTR 5 is equipped with flagship-level Bluetooth chip from Qualcomm the CSR8675, which supports Bluetooth 5.0 and supports a lag-free Bluetooth experience.
FiiO BTR5 features all the bluetooth formats ranging from AAC,aptX,aptX HD,aptX LL,LDAC and more.
The FiiO BTR 5 features a battery of 550mAh, which provides continous music playback of upto 9 hours, and even if that is not enough for you the BTR 5 just need 1.5 hours of charging time to fully charge.
FPGA, along with the help of dual active audio crystal oscillators, greatly improves the sound quality, making it noise and jitter-free with providing a stable connection.
The FiiO BTR5 features a 0.49 inch OLED display which displays pairing mode, Connection status, call status, power status, encoding format, and volume, which you can also use to view charging status, adjust or change EQ setting, enable car mode and more.
The FiiO BTR5 has an omnidirectional microphone with cVc 8.0 noise cancellation which adjusts the microphone's gain and suppresses the background noise which makes call quality crisp and clear.
The BTR5 offers one-touch NFC connection which makes it very easier to connect to NFC enabled devices.
The BTR5 is built strongly with aluminum alloy body, which is paired with a curved glass on the front and backside, making the device smooth and tough.
The Device looks brilliant and has a strong build quality.
The BTR5 has a one multi-function button that does all the functions like, play/pause/pairing/accept call/reject call/hangup/open voice assistant.
You can download FiiO Music App and remotely control different functions in the BTR5 like switching between different low pass filters, changing EQ setting and many more.
1. Update from Bluetooth 4.2 to Bluetooth 5.0
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.

Alta fedeltà in bluetooth
E' un apparecchio molto comodo per telefonate e altro. Ma soprattutto ha una qualità audio molto elevata. Nulla a che vedere con BTR3 che pure è molto versatile e migliore dei suoi predecessori. Qui la differenza la fa uno stadio di amplificazione top level e la possibilità di streaming bluethooth in LDAC. LDAC è supportato dal DAP Fiio M11 per esempio ma anche dagli smartphone samsung galaxy ultima generazione. Con BTR5 si può godere in totale mobilità di IEM top level con una qualità di sorgente appena un po' sotto il collegamento diretto ad un buon DAP.
