The game mode and ambient mode will be added. And the LHDC support(beta version) will be available in the new firmware.

Best regards

That is awesome to hear as my Poco F2 Pro does support LHDC! Looking forward to the new firmware update!

There is one other thing. After the latest update on the App, there is a drop-down banner, appearing for a few seconds, which is empty. Before the App update it used to show something but I cannot recall what. I'm not sure if you can reproduce the same error in your devices but it would be nice if it could be fixed.

Are we thinking EQ will be added on the next firmware AFTER this upcoming update?
All my IEM sound so muffled..

I hope the EQ will be added soon as well. But the next firmware after this may be available at about May or later.We need to wait....

Best regards

Is there any way to see the actual sample rate (up to 96kHz) and the bit rate (up to 24 bits) the UTWS5 is playing? Can this be seen now from some App? If not, can this be implemented in a future update?

Honor/Huawei phones support LHDC by default?
Thinking to get Honor 50

As far as we learn, Honor/Huawei phones support HWA 2.0 but not LHDC 3.0 or 4.0.

Will these True Wireless Bluetooth Earhooks have LDAC anytime soon? What kind of update can we expect next year?

No LDAC available on hardware level for these.

 

[felix3650]

If I'm not mistaken, Hiby Music (the app) should have a LHDC option. Once the new firmware comes out, we can try that (for phones which don't have LHDC natively).

Any one use these with a m11 Ltd, what codecs do u get and what can y choose from an the dap?

We feel regretful to inform you that there is still no progress in the support of LDAC. It is mainly because SONY and Qualcomm have not successfully debugged (even if LDAC has already been implemented in other Bluetooth platforms). As the application party, we can only wait if there are no source codes.

Will the EQ be parametric or fixed bands?

If it's fixed bands, what configuration will you use? I'm really hoping that you'll follow the configuration used by the AutoEq (https://github.com/jaakkopasanen/AutoEq) project where:

Q=1.41

and the frequency bands will (at least) include:

31 Hz
62 Hz
125 Hz
250 Hz
500 Hz
1000 Hz
2000 Hz
4000 Hz
8000 Hz
16000 Hz

For instance: https://github.com/jaakkopasanen/AutoEq/tree/master/results/crinacle/harman_in-ear_2019v2/FiiO FH5s

Do you have have any idea if your devs will be doing it like that?

The EQ in UTWS5 will not be parameter Equalizer. It will include 10 bands EQ adjustment.

If only The HiBy music app could gain Qobuz streaming support like it does for Tidal. So that I could use LDHC streaming with the UTWS5.

The new firmware V1.4 for FiiO UTWS5 is now available!

The UTWS5 features a programmable Bluetooth processor platform, which has very powerful processing capabilities, especially in audio performance, which can be highly customized.

Since the release of the product, our R&D team has continued to tap the potential of the QCC5141 platform, gradually digging out the "Ambient Sound Mode" and "Game Mode". Now, the Beta testing of LHDC is officially open!

It is worth mentioning that the UTWS5 has recently acquired the "Snapdragon Sound" certification from Qualcomm.


The following changes and improvements have been made in V1.4:

1. Added Ambient Sound Mode
After enabling the Ambient Sound Mode, we can easily catch up with small talks with our friends, hear the sound of vehicles on the road as well as the arrival reminder in the subway without taking off headphones.

Triple-click the button on the right earhook to enable the Ambient Sound Mode. Also, we can enable it on the FiiO Control APP: UTWS5->Audio->Ambient Sound, and adjust the gain here.

2. Added Game Mode
Turning on the Game Mode can significantly improve the low latency in the Bluetooth transmission process.

Tested by FiiO Labs, the aptX Adaptive can improve the latency by about 27% while the aptX can improve by about 41%.
**When connecting the UTWS5 to the Mi 10 in aptX Adaptive codec, the measured latency goes up to 165ms with the Game Mode off, while the latency goes down to 121ms with the Game Mode on.
**When connecting the UTWS5 to the Huawei P20 in aptX codec, the measured latency goes up to 255ms with the Game Mode off, while the latency goes down to 150ms with the Game Mode on.

3. Added LHDC Bluetooth codec (beta version)
LHDC is a high-definition Bluetooth audio codec technology with similar performance to LDAC, both of which support up to 96k/24bit audio transmission.

When LHDC was HWA at first, FiiO took the lead in applying this technology to the BTR3 stereo Bluetooth amp. After years of technical iterations, it is now becoming more and more mature. In addition, some Chinese mainstream mobile phone manufacturers (such as OPPO, Xiaomi, vivo) have gradually included the HD Bluetooth transmission of LHDC, making this technology more and more popular.

In order to meet the needs of more audiophiles for high-definition sound quality of TWS Bluetooth transmission, we decided to introduce LHDC again and try it out on the UTWS5 first after careful consideration.

4. Miscellaneous improvements on performance.

Notes on upgrading the UTWS5 firmware:
1. It is not suggested to reverse back to the previous version after upgrading.

2. Before upgrading, it is suggested to check whether your mobile phone supports LHDC. You can check the list provided by LHDC team here: LHDC supporting list_ Phone(Provided by LHDC team)

3. If the sound stutters, please try to stay away from interference sources (such as routers or wireless keyboards and mice, etc.). Or go to the "Developer options" on the mobile phone to adjust the transmission bit rate to "Adaptive"

4. Due to the difference in the operating system of mobile phones and LHDC versions, it may be connected not as LHDC by default. At this time, please select the LHDC codec in the Developer options menu on the mobile phone.

Some issues of concern
1. Will the subsequent firmware be updated again?
--Yes. We will continue to make optimization and enrich more functions for the UTWS5 since it is our pioneer product in the HiFi TWS field.

2. What is the LHDC version this time?
Our beta test this time is the 3.0 version customized by LHDC for adaptation to the Qualcomm platform. There will be a higher version 4.0 adaptation in the future.

3. When will the LDAC be supported?
Currently, the UTWS5 does not support LDAC. But as the application party, we are working hard with our partners for stable and efficient audio transmission.

Sorry to be a bummer, but the amazon cloud file is down, looking forward to it, as soon as the link or the files are fixed.
