Qualcomm announces its new QCC305x SoCs for future mid-range TWS earbuds with high-end specs

[Redaktion]

Qualcomm has unveiled the new QCC305x series of chipsets for TWS earbuds. The OEM claims it can be used to make new products in this category that are cost-effective yet have some current or upcoming premium specs. They include audio-sharing between multiple earbud sets, Adaptive ANC and Bluetooth LE Audio

Qualcomm had Broadcast Audio and TrueWireless Stereo as proprietary technologies but LE audio has standardized both so now the only other important tech that matters is aptX Adaptive for true low latency so perfect AV sync is maintained. Once that is available via LE audio, it will be Bluetooth audio heaven. Sadly there are many obstacles.

aptX Adaptive only seems to show up in receivers and phones. There aren't Windows PC M.2 or USB modules/transmitters with aptX Adaptive (although there are plenty with the earlier gen aptX Low Latency) but aptX Low Latency can't be in phones because it requires a separate dedicated antenna for Bluetooth whereas aptX Adaptive works with a shared antenna. Windows also doesn't support to support aptX Adaptive yet nor aptX Low Latency (aptX LL is supported via third party USB transmitters and receivers).

Also from what I saw on Bluetooth SIG's website, the codecs supported on classic Bluetooth may not necessarily be the same as the codecs supported on LE audio (Low Energy radio). That is, the vendors need to implement those codecs on both radios if the chip supports LE audio and classic for backward compatibility.

And so called "flagship" phone makers like Samsung are not supporting aptX Adaptive in their phones even though a lesser known brand like ASUS Zenfone 7 is.

All in all Bluetooth audio is still a mess and we still don't have universal low latency or really long battery life/product life in earbuds or perfect left-right sync in many Bluetooth products.
