Fiio BTR3 - Discussion Fiio BTR3Official site |
Discussion пїЅ Description
FiiO BTR3 is the first Bluetooth amplifier in the world that supports all modern wireless audio codecs at once: SBC, AAC, aptX, aptX HD, aptX Low Latency, LDAC and LHDC. This comprehensive Bluetooth audio support will allow you to get the best sound possible from any source and breathes new life into your favorite headphones.
The LED indicator will let you know which codec the sound is now transmitted: when playing SBC, it flashes blue, with AAC - blue, LDAC - white, LHDC - green, aptX and aptX LL - purple, and finally, when playing aptX HD, it flashes yellow.
Qualcomm's Bluetooth CR8675 chip used in the BTR3 is a premium device designed specifically for audio devices with high sound quality requirements, supporting audio transmission and processing up to 24-bit resolution and equipped with its own 120 MHz processor. In addition, the CR8675 chip also demonstrates the stability of the connection among other analogues, especially in circumstances with a lot of interference.
The digital audio signal received without wires is transmitted by a Bluetooth chip to a separate DAC, AK4376A from Asahi Kasei, which converts it to analog with extremely low distortion (в€’107 dB or 0.00045%) and a very high signal-to-noise ratio (124 dB) - you will hear every nuance and every detail of your favorite music.
11 hours of pleasure. A 300 mAh battery is charged in just an hour and a half, and then it works for almost half a day! (The duration of work on a single charge was measured using the AAC codec, the use of more complex codecs can consume a charge faster.)
Two layers of volume control for fine tuning. When the smartphone is paired with the BTR3, its own volume is adjusted on it, and the BTR3 has its own independent volume control, which allows you to find the level that is comfortable for you as accurately as possible. Of course, if you turn off the BTR3 - it will not forget at what level you used it, and remember it the next time it is turned on.
Built-in noise-canceling microphone cVc from Qualcomm. The electronics in BTR3 cares not only about making your songs sound good - even your phone calls should sound good. In addition to the high-quality amplification of sound coming from the microphone, VC technology automatically adjusts the sensitivity of the microphone and actively suppresses background noise - let your interlocutor also get a little pleasure from high-quality sound.
Simple one-touch pairing with NFC. A compatible device can be connected to the BTR3 by simply holding one to the other. Yes, no more settings menu is needed.
Type C connector with USB-DAC function. The BTR3 is equipped with a Type C USB connector, which is more convenient due to its symmetry, and the device itself through this connector can not only be charged, but also used as a USB DAC - and without the need to install drivers.
If you connect your smartphone to the BTR3, and the BTR3 to the audio system in your car, you can not only listen to music in the cabin, but also answer calls conveniently.
Liven up your home theater. Is your home cinema system not equipped with Bluetooth? Replace the audio cable on the BTR3!
The aluminum alloy case, covered with smoothed glass with oleophobic coating, contrasting black letters and smooth texture - this makes up an appearance that would not be superfluous on the window of an expensive workshop.
Double tapping the multifunction button on the BTR3 will trigger Siri - almost like on your iPhone.
Fast Pair. The Android OS has the Fast Pair function, which BTR3 also supports - hold the button on it and confirm the connection in the pop-up notification on the smartphone.
Wear whatever you want. You can attach BTR3 to clothes with the help of a clip, you can hang it on a neck on a cord. The main thing is that you do not have to wrestle with how comfortable it is to place it.
