A few years ago, Apple launched the new Airpod Pros, which not only improved the gaming function, but also had excellent active noise reduction function, which brought great encouragement to the market.
Now, Qualcomm has launched two new SoCs designed for true wireless earbuds, the Qualcomm QCC5100 and Qualcomm QCC302x series. The Bluetooth audio SoCs are designed to help users use their devices for voice calls and music streaming for longer periods of time.
According to reports, Qualcomm QCC304x is an entry-level flash programmable Bluetooth SoC that targets more affordable low-end and mid-range earbuds. It has a single DSP core that is "not programmable, but configurable." This means that manufacturers will be able to adjust DSP settings, but cannot install new profiles themselves. It will also support button activation of the assistant instead of wake-up.
According to Qualcomm, the QCC514x is the flagship of the new chips. It supports wake-word voice assistant activation (such as Alexa and Google Assistant) and has dual DSPs that can be fully programmable by earbud manufacturers. If they have the choice of different extensions, whether their own or third-party, they can load them. Still, the new power management system means you can get up to 13 hours of playback time on the headphones using a 65 mAh battery.
The solution has the following features:
Qualcomm TrueWireless Mirroring technology provides a seamless user experience
True wireless earbuds are completely wireless, with the freedom to use either the left or right earbud to act as a stereo pair or a mono device. Since only one earbud can be wirelessly connected to a phone at a time, Qualcomm TrueWireless Mirroring technology is designed to easily swap between any earbud connected to the phone, with the other earbud mirroring the connection.
For example, if a user removes a connected headset from their ear, the headset that is mirroring the connection will take over the link so as not to interrupt an active voice call or music stream. Another reason a role swap can occur is if the mirroring headset is detected to have stronger RF connectivity than the connected headset, perhaps due to the distance the user is moving their mobile phone. In this case, the connection is designed to seamlessly switch from one earbud to the other. This provides a superior experience with no audio dropouts, and the user will not be aware that the swap has occurred.
Immersive listening and natural sound with ANC
Qualcomm's 2019 State of Gaming report shows that more than 63% of consumers want active noise cancellation (ANC) features in wireless headphones and earbuds. ANC technology helps reduce unwanted background noise, allowing users to enjoy a more immersive listening experience. Once reserved for high-end stereo headphones, consumers are now actively seeking this feature in true wireless earbuds at all price points.
The new Qualcomm QCC514x and Qualcomm QCC304x SoCs integrate Qualcomm's breakthrough ANC technology and highly natural pass-through capabilities. This technology is designed to use microphones on the outside of the earbuds to leak certain sounds from the outside world with very low latency, so you can hear the sounds around you in real time for a natural experience.
On the active noise cancellation side, Qualcomm promises support for multiple filter presets, and that manufacturers will be able to switch between them, like using a companion app on the wearer's smartphone to adjust the strength of the ANC without glitches. Qualcomm says there are microphones on the outside of each earphone, and the QCC514x flagship has a latency as low as 10 microseconds, so the blending of "air leak" sounds with ambient noise should also be more natural. ANC can also be used during voice calls.
Qualcomm says the goal of the new chipset is to help deliver products that can be worn on the ear all the time, even when people aren't actively listening to music. This includes not only accessing assistive technologies, but also using ANC, etc. Qualcomm and earbud manufacturers don't necessarily expect them to be safely charged in a carrying case when not being used for music playback, which places huge power requirements on the SoC.
Qualcomm is not offering Bluetooth 5.2 support for LE Audio just yet. Qualcomm notes that this is mainly because the Bluetooth SIG has not yet finalized these profiles and that they are not expected to happen until the second half of this year at the earliest. However, beyond that, there are also changes in the new chips that Qualcomm hopes will support LE Audio.
Currently, Qualcomm plans to start shipping its new chip to manufacturers in April. In addition, the company said it expects new products based on the SoC to hit the market in the second quarter of 2020.
