Is the 'reduced delay' feature really good enough for watching TV/videos?
Note:
Before 22B1 batch: TWS116 is defaulted to "TV mode", you can four-click the MFB button to enter normal mode if you don't need the ‘reduced delay’ feature.
After 22B1 batch: TWS116 is defaulted to "TV mode" and the normal mode is cancelled.
The TWS116 uses a new chipset with embedded technology which achieves a noticeably reduced audio latency using the standard SBC codec. Normally SBC imparts a 220ms delay, however by decreasing the transmission bandwidth to increase speed, the TWS116 solution can reduce the delay by 50% to only 110ms. By comparison, the latency of aptX LL is only 40ms. However aptX LL requires both transmitter and receiver to support aptX LL while SBC is standard on ALL Bluetooth devices.
During user trials we found that most people didn’t notice significant latency when using the SBC reduced latency codec and of those who did notice a delay, most still found it acceptable.
| Output Device | Latency |
| TV's Built-in Speaker and Wired Speakers |
None |
| Headphones on aptX Low Latency or FastStream |
~70 milisecond |
| TWS116 (SBC Codec with Reduced Latency) |
~100 milisecond |
Since the SBC codec is standard on all Bluetooth devices, you can benefit from the reduced latency SBC codec no matter what you connect your TWS116 to - whether it’s to our Bluetooth transmitters, your mobile phone, tablet or your PC. In all cases, the latency will only be 110ms - 50% less than that of traditional SBC.
Please note however, that as mentioned it is not 100% latency-free. And some sensitive users may notice the slight 0.5 word delay. If zero delay is very important to you, we recommend you check out our TV set section.
