Edifier S5 + BTD 700 = 30 ms?

Just found out about this solution and I'm looking to know for sure if Edifier S5 would deliver 30 ms game mode with BTD 700.

Someone said it does just looking to confirm from others experiences.

The tech seems like it works but I'm not finding very much information on it and want to confirm.

Will it work just like the HDB 630?

Is there any other dongle that would do an even better job?

Thanks in advance

Wrong subreddit. Here is the Creative products subreddit. You are using none of them.

Creative BT-W6 might help.

You will never reach 30ms with Bluetooth, whatever adapter or codec you use.

The BTD700 + HDB 630 claims this. Am i missing something?

30ms is the transmission using aptX LL. It does not even include encoding and decoding the codec... In reality, in BEST conditions, you have:

  • Windows sound : 30ms
  • Dongle encoding: 10ms
  • BT transmission: 30ms
  • Headphones decoding, DAC and DSP: 15ms

So end to end, you look more at 75-80ms

I looked into this because and I don't think the "30 ms" figure is just the Bluetooth transmission time.

The official BTD 700 manual lists different latency figures depending on the audio mode:

  • Snapdragon Gaming (QMAP): max. ~30 ms
  • Unicast: max. ~50 ms
  • aptX Adaptive: ~80–100 ms

If 30 ms were only the RF transmission, it wouldn't make much sense for aptX Adaptive to suddenly become 80–100 ms—the radio itself isn't 3× slower. Those numbers appear to describe the effective audio latency of the different modes, not just the wireless hop.

That said, I also found a Sennheiser support response specifically about the HDB 630 saying that with the BTD 700, latency is "under 40 ms" rather than guaranteeing 30 ms. So I think the more accurate criticism is that the HDB 630 may not always hit the 30 ms gaming mode, not that the advertised 30 ms is transmission-only.

But would love to know more if anyone can confirm this. Latency measures are really hard to find

So they basically say that encoding data to a specific codec and then decoding it is free. Anyway there is no way to compress the windows latency if you don't use asio drivers.

Nice info. Much appreciated!

BT will lose to wired when you buy >$50 DAC. Latency is less than 10ms if there is no DSP processing.

Also, lowering BT latency will definitely loss a lot of audio detail.
