Does Shanling plan to offer any LHDC or LLAC products in the near future?

May I ask for what purpose are you interested in the lowest possible delay? If it's for gaming, I must recommend to look for transmitter and headphones with aptX LL, as that's only one that will truly offer you lag free performance.

Gaming but also voice chat (discord). HFP/HSP Codecs presently work but sound quality is poor, however it offers less delay. aptX LL is a solution right now, but wondering how many long until we have LLAC transmitters/receivers as that would be the "best solution" since they are Low Latency with High Quality.

Does Shangling offer any LDAC & aptX LL devices that allow USB-DAC? I've gone through almost all of the 'parameters' without luck.


Thank you for the answers and your time.

If you are talking about USB Transmitter, then no, none of current Shanling product offers aptX LL or LHDC in this mode.

Hello, I am dance instructor and during the class I use iPhone SE with Shanling UP 2 to controll the music.
For me the highest priority is signal stability, not the sound quality. So, I have a few questions:

1. What bluetooth codec ensure best signal stability? As I know, iPhone SE has AAC and SBC codecs.

2. I am planning to buy leather belt holster for my phone, because it is more comfortable, than keeping phone in the pants pocket. Will such a holster affect the signal stability?

3. I had asked this question before, but no one knew the answer. Maybe someone knows now: when I use UP2 with my iPhone SE, there is problem with volume. When I stop the music and after a while play it again, the UP2 don’t respond to volume changes from my iPhone for a dozen of seconds. It’s quite a lot, especially during dance classes. After a while the volume changes and everything is ok, until when I stop the music again and then play it after a while. Has anyone know how to fix it?

My experience with RECEIVING,

AAC is honestly “the best” on iPhone for music. Used it with Q5s and iPhone 6 SE all the time. Using UP4 with iPhone XS now.

AAC might affect the UP2 battery life? (Not sure!) Anyway, since AAC doesn’t use more “physical bandwidth” than SBC, the connectivity issues should be equivalent and AAC should normally be preferred from an iPhone device when latency is not an issue. (iPhones encode AAC well, unlike many Androids..)

That said, my UP4 (and likely UP2) only have ~10-15ft range without breaking up steaming. With ES100 or Q5/Q5s, I could get up to >20ft before the AAC started breaking up. Of course, highly depending on walls and such..

At close range with AAC there are ZERO “hiccups” on the UP4. Even though the Q5s has a longer sustained range, it would sometimes “hiccup” at only a few feet.

Oops.

My Shanling Q1 has a better reception range than my UP4.

The updated Android app says there ist a new firmware 1.2.5 but the update process doesn't work when it is started.

 

[Shanling]

Firmware updates for Shanling UP2 & UP4 are now available.​

Smoother and faster re-connecting and Volume memory setting available in Shanling Controller app.

OTA didn't work on my UP2, so had to do it manually using dfu-util on linux. Now showing as v1.7.5

Yes, OTA updates are available only for certain runs of UP2 and UP4 (only units manufactured in past few months), older units still rely on manual update through Windows.
We mentioned it on our website.

Yes, understood. I had to try OTA first to understand it didn't work Not a criticism, just pointing out that you can also update without Windows for manual install.

 

[YamabushiJapan]

Gave the new firmware a try, but unfortunately the volume limitation issue still exists. I can not achieve a loud enough volume when connecting my UP2 to my computer via USB Bluetooth dongle. This was not an issue with firmware v1.5. Please, do something to raise the maximum amplication/volume level in your next firmware release.

Will all UP4 ultimately be able to upgrade via bluetooth?

Kind of let down if they do not.

It's not something that can be adjusted by simple firmware update, this change needs to be done on deeper level in our factory.
