, as major manufacturers have canceled 3.5 earphone holes, the high-end earphones in the hands of many fans have become more and more useless, and they have also sighed.Bluetooth Headsetthe sound quality is not good, which also makes many manufacturers see new business opportunities and have launched Bluetooth one after another.headphone amplifier,FiiO's BTR series is one of the best, especially the introduction of BTR3. With its small size, it supports Aptx HD,LDAC and HWA three high-quality Bluetooth modes. Independent DAC and good sound quality have captured the hearts of a group of burning friends. This time FiiO has launched an upgraded version of BTR3, BTR3K. Can BTR3 be reproduced? Let's discuss with you.

one. Unpacking
Before unpacking, let's look at the differences between BTR3K and BTR3 and other models. We can see that there are still many improvements compared with BTR3. Bluetooth is upgraded from 4.2 to 5.0,DAC is upgraded from monolithic AK4376A to dual AK4377A, and independent dual crystal oscillator is added to support balanced output. It can be said that BTR3K is more like a brand-new product than a simple upgrade of BTR3.
FiiO BTR3K is mainly white with black pictures and fonts, which is a classic color scheme.
, it can be seen that the two mainstream high-quality transmission modes of APTX HD and LDAC are still supported in BTR3K, while HWA is not available.
open the box, you will find BTR3K is so small.
BTR3K has a circumference of 58*25*11mm, which can be said to be very small, and 2.5d glass panels are used at the front and back, which is very good in appearance and hand feel.
has a Hi-Res gold mark on its back.
the charging hole of the current popular Type-c interface, a short charging cable is randomly attached.
Compared with the previous generation BRT3, the biggest upgrade of BRT3K this time is that it supports balanced output and is a dual-drive true balanced architecture. It is matched with two AK4377A to decode and drive the left and right channels respectively, so that both the driving force and the listening sense are obviously improved. However, the biggest problem is that the balance port adopts 2.5 interface, which requires switching for most devices, while the standard does not have switching wires, it's a bit cumbersome to use.
BTR3K is made of aluminum alloy, and the texture is also very good. It also has a built-in full pointingmicrophone, but also supports the eighth generation CVC call noise reduction technology, so that we can easily connect those wireless headphones and turn them into Bluetooth headphones that can talk.
FiiO matches BTR3K with a back clip, high-permeability material, which is quite good to match.
in general, BTR3K's workmanship and color value are excellent, and it is small and portable.
2. DAC mode experience
decided to test the DAC mode of BTR3K while charging. BTR3K's breathing light is very good. Different colors represent different schemes, red: charging, blue: SBC, cyan: AAC, purple: aptX, yellow: aptX HD, white: LDAC. Through the color of the breathing light, we can master the current transmission mode.
on win10, BTR3K is drive-free and can be identified and used when plugged in.
Although BRT3K has two AK4377A DACs built in, in USB mode, it is not these two DACs that work, but the Bluetooth chip CSR8675 to provide DAC functions, so it still cannot catch up with those more professional DACs in performance and listening.
In fact, I think BTR3K's USB DAC mode will be more practical if it can provide transmitter function.
3. Bluetooth mode experience
Next, I will experience the highlight: Bluetooth. BTR3K's Bluetooth master is still the CSR8675 classic chip and is still at the top level in terms of performance. The biggest upgrade of BTR3K this time lies in the upgrade of DAC chip, from single-chip AK4376A to dual-chip AK4377A. Although the AK4377A is not outstanding in many DAC master controls, it is still more than enough to deal with Bluetooth transmission. In addition, BTR3K has also introduced 22.5762M/24.576M independent double crystal oscillator into this level of products for the first time. The advantage is that jitter is greatly reduced. It can be said that BTR3K's architecture upgrade is still very large. The new dual-drive true balance architecture has been significantly improved both in terms of data index and actual driving force. However, the biggest regret is that the balance port is a 2.5 earphone hole, which, however, there is no standard patch cord in this random, so it is impossible to experience its real strength. However, even in single-ended mode, dual DACs still work together, which can theoretically provide better listening feeling and make me have more expectations for the actual audition later.
, I found BTR3K a very good use. Because of its ultra-small size, low output power and enough to push some big ears, we can easily transform a big ear into a Bluetooth headset. Moreover, because BTR3K has a built-in full-pointing microphone, it can also solve the problem that the traditional big ear has no wire control. For example, the SHP9500 I matched this time is based on BTR3K SHP9500.
BTR3K supports two high-quality lossless Bluetooth encoding, aptX HD and LDAC. Some people say that LDAC has a better sense of hearing than aptX HD, but maybe my fungus or the equipment is too poor. I think there is no obvious difference in actual hearing. If I blindly test, it is definitely impossible to distinguish which transmission mode is currently available. Here, we still choose the default LDAC and adopt the best sound quality mode as possible.
FiiO has a special setting app:FiiO Control for its own equipment. We can set the machine here, such as DAC's working mode, input priority, equalizer, filter and other contents to adjust. There are many adjustable options, but it is still very simple to use.
In addition to setting up app,FiiO has also specially developed a player:Feiaomusic. UI is very simple, the playing interface is not too fancy, song information, lyrics matching are relatively perfect, the biggest advantage is to support LAN playing, if you have NAS, you can build a media library, so you can not be limited to the storage space on the mobile phone.
, I would like to talk about the sound performance of BTR3K. With the blessing of LDAC, BTR3K's performance is still very good. Although there is still a gap from the direct push of the mobile phone, it is not very big. Of course, it is to exclude those HIFI mobile phones with independent DAC. The overall trend of the sound line of the machine is relatively neutral and young, with good resolution, high frequency, the amount of low frequency is not large, and the dive is not very deep, but the control is not bad and does not appear to be scattered. Listen to Xiong Tianping, Zhang Xinzhe and other relatively clear voices perform well, listen to Chen Jieli and other female voices are very good, for good sisters and other medium frequency thicker are younger.
. About choosing Bluetooth like BTR3Kearmuffor direct access to TWS earplugs is estimated to be a problem that many people have considered. Personally, if I simply commute from the street, TWS will be more convenient, and those with noise reduction will be better used in subway buses. If the sound quality requirements are relatively high and there are several high-end plugs with good sound quality in my hand, then BTR3K high-quality Bluetooth earphones supporting LDAC aptX HD are your good choice.
IV. Summary
advantages:
1. Small size and exquisite workmanship.
2.CSR8675 master, supports aptX HD and LDAC lossless Bluetooth encoding.
3. Dual-DAC dual-drive architecture.
4. Independent double crystal oscillator.
5.RGB breathing light to keep abreast of the current Bluetooth status.
6. With omnidirectional microphone, ordinary headphones can be changed into wire-controlled headphones without affecting the call.
7. USB DAC mode is supported.
:
1. The balance port is a 2.5 earphone hole, which is not very convenient to use.
2.USB DAC mode would be better if 2 blocks of AK4377A can be called.
3. It is better if you support Bluetooth transmission. One machine can use multiple functions.
Under the tide of TWS, Bluetooth has basically become the most commonly used audio transmission mode for mobile phones. Compared with TWS, BTR3K gives high-end earplugs with outstanding sound quality a chance to glow again at a lower cost. For those friends who have sound quality requirements, it is a very good solution.
