aptX Adaptive / aptX Lossless USB Transmitters

[purplesun]

The EDIFIER TWS1 Pro headphones do not have a game mode.
T10P 24 Bit switching works like this:

I have been using the YET-T10P with TWS1 Pro or Spirit S3 for several weeks now. Purely listening to Tidal playing from PC to all over my apartment on AptX Adaptive. Not using for gaming. The only time I switch to low latency (triple-tap to constant blue LEDs) is when I go bad signal location with TWS1 Pro, like the toilet. LL mode seem to make the signal more stable in bad areas. (Correction: constant blue LEDs is SBC mode)

Nura just dropped a big hint that they might be shipping their aptX Lossless QCC3071 adapter to preorder customers now instead of their QCC3056-based one. This is a great surprise - especially given we only paid £30 for the adapter. Although they have also admitted that production isn’t on track with shipping slipping to next month instead of this month.

I ordered KB8P 24 Bit, asked the seller for a program for it, sent v1.6.
By the way, it differs from the version posted here.
Here is version 1.6 from the seller, it may be useful to someone.

As soon as I receive the goods, I will let you know if there is a difference in delay between the Aptx Adaptive High Quality and Aptx Adaptive Low Latency modes.

Hey guys, I'm back with very disturbing finding about Creatives sound quality. Few days I was listening my favorite songs and I started to hear some sound distortion especially in calm and silent passages. It's hard to describe, but if you remember the days when first mp3 lame codecs were implemented with very poor quality and you could hear some high pitch distortion/crackling "far in the background". I couldn't believe what I hear for 60€ so I tried also my other laptops with same result. Ok lets hear KB8P once I get it and it arrived today and as you can guess, KB8P doesn't produce such sound.
I'm very disappointed and also surprised that device with sub thirt price have better aptx adaptive implementation. Don't buy Creative BT-W4, at least not yet!
I could just simply return it, but it doesn't help to solve issue so I would like to somehow report this sound issue and push Creative to solve it. Best way would be to record it but I'm not aware of the way how to do it. Without prove it's just subjective opinion of one of the customers.

@chigolberi I can confirm that there is difference between High Quality and Low Latency mode just by watching some youtube videos where someone is talking. Lipsync is better with Low latency, but don't expect cable like experience. It's less but still there.

klaboor, thank you for the information!
I have a Microsoft Xbox One + Wireless PC adapter, if you connect headphones to the controller, then there are no delays in the sound, I do not feel at all. The sound is transmitted in 16 bits 44 Hz.
How they achieved this...

Does Creative BTW 4 have a delay in Aptx Adaptive mode ?
There is also such a certified Sennheiser BTD 600 adapter

Thanks, looks exactly the same apart from does not have the "Translated by...."at the top (someone here did that for us) and Icon is squarer.

In the one that the seller sent, there is no "Enable microphone" function.

 

[helmutcheese]

There is on v1.6 we have that was Translated to English by a user here but not on the new one you linked to us, so I have the same as you have above.

My seller only had v1.5 and said v1.6 was not in English yet.

My seller only had v1.5 and said 1v.6 was not in English yet.

Version 1.6 with the translation "Translate by Superatom" looks like this is the version taken from here: http://www.hstech.com.cn/index.php?c=content&a=show&id=115
This is a closed beta version, an extended option has been added to turn on the Bluetooth headset microphone.
KB8 must be used with firmware V1.8 or higher.
KB8P must be used with a suitable firmware version V1.5 or higher.

No, other than sound issue I described the Creative BTW4 is great. I think that low latency has priority over high quality. I can say it's pretty similar to the KB8P Low Latency mode.
I cannot order Sennheiser BTD 600 in EU, only BTD 800 is available here for us but it looks like older version, only 4.2 bluetooth. Not sure why they choose such naming, but I will order it through person in UK where it is available so I will get hands on this as well.

There may be strong interference, you need to try on another PC and away from interference sources.

I'm in aread with zero interference. I have also turned OFF all 2,4GHz Wifi access points and also all Bluetooth smarth home devices. Still same result. I have also tried it on my laptop in my cellar which is under ground with totally zero interference even from neighbours wifi networks. Still same.
I already recorded both dongles but I cannot hear distortion so there is clearly problem in bluetooth part.

Maybe a marriage, or a bad implementation.
Maybe write to support, they will release a fix, the firmware of the device will most likely be updated.

Look in the application, maybe a new firmware has been released.

You have Creative dongle as well? Is this your control panel? I do checked everything and everything is up to date. Btw I ordered Sennheiser BTD 600. Will see
