LC3+ TWS are here! Excited to see RTINGS review.

Some LC3 dongles I’m watching in case they offer better Latency results comparing with Asus’s provide RF dongle.

These headphones come with an LC3 / LC3+ dongle that can be used with other devices, similar to popular BT-W5 dongle.
Note: Theres 2 new dongle models, Creative BT-L3 and Creative BT-L4 USB Transmitters, one may preform better then the other, not sure at this stage.

BT-L3 details (with manual) https://www.head-fi.org/threads/aptx-adaptive-aptx-lossless-usb-transmitters.961856/page-112#post-17775459

2) Crowdfunded USB dongle transmitter https://www.velacy.com/products/dongle

Another dongle with very communicative development team

Any updates on when this product might be tested?

If all goes as planned we should begin testing this product on friday!

Waiting for it!!

Please, compare them to razer’s hammerspeed pro (one that comes with dongle) also sony’s inzone buds. Also if you had to choose any in the market, which one would you pick to cover all scenarios, gaming (for fps, latency it is important) music, and calls. Thanks!!!

Thanks for the review. How is the noise floor on these compared to the Sony Inzone buds? The latter was retested having a “slightly high-noise floor compared to other headphones”. Meaning you can hear an audible hissing sound when no sound is played.

ASUS has provided these details on how to change LC3 and LC3+ codecs

The ROG CETRA TRUE WIRELESS SPEEDNOVA does not have the capability to switch between LC3 and LC3+ in 2.4GHz mode. LC3+ is specifically designed for Bluetooth audio transmission and is not applicable to the 2.4GHz wireless mode of the ROG CETRA TRUE WIRELESS SPEEDNOVA.

To switch between LC3 and LC3+ on the ROG CETRA TRUE WIRELESS SPEEDNOVA, you can follow these steps:

1. Ensure that your ROG CETRA TRUE WIRELESS SPEEDNOVA earbuds are connected to your device via Bluetooth.

2. Open the Bluetooth settings on your device and find the ROG CETRA TRUE WIRELESS SPEEDNOVA in the list of paired devices.

3. Tap on the settings icon (usually indicated by a gear or cog symbol) next to the ROG CETRA TRUE WIRELESS SPEEDNOVA device.

4. Look for an option called “Audio Codec” or “Audio Quality” in the settings menu for the ROG CETRA TRUE WIRELESS SPEEDNOVA.

5. Tap on the “Audio Codec” or “Audio Quality” option to open the submenu.

6. In the submenu, you should see the options for LC3 and LC3+. Select the desired option you want to switch to.

7. Once you have selected your preferred audio codec (LC3 or LC3+), exit the settings menu.

8. The ROG CETRA TRUE WIRELESS SPEEDNOVA will now switch to the selected audio codec and you should experience the improved audio quality of either LC3 or LC3+.

Hello cattboy,

During our testing, we did not notice any outsanding noise floor issues with the ASUS ROG Cetra TW SpeedNova Buds. However, keep in mind that the noise floor of audio devices can be subjective depending on your hearing sensitivity.

Thanks David. Re:

While electric noise floor is always present, it varies drastically between brands/models, an important part is if the noise floor is audible vs inaudible (perceivable) for a human, shifting a buyers purchasing decisions (subjectivity).

Data driven perspective, theres value of adding this metric to the testing methodology, as it may weed out edge cases of “this headphone has a defect as mine sounds bad while Rtings didn’t record an issue under intense testing”.

For example, my Epos gtw 270 hybrid TWS have an inaudible noise floor, compared to the Sony Inzone buds which is always present and heard. The Inzone buds review was edited post publishing to amend that detail. My WHXM3 also have no audible noise floor.

With everyones hearing/ears being different, a way to identify/quantify what a headphone /TWS’s noise floor is in Hz/dB, may help users prone to specific values as being subjectively bad, acknowledge and learn to avoid those ranges or values if provided in the review writeup.

Example (made up numbers) GTW270 - Noise floor 2dB Inzone - 10dB

Thanks for reading and the effort you folks put into the review process.

Hi David, cattboy,

ASUS does not offer a method to use LE audio without a dongle. Therefore, selecting LC3/LC3+ transmission via Bluetooth connection is not feasible. Could you please help us remove this statement? Thank you very much for your assistance.

Thank you for providing the relevant information. I’ve tested it on my side, there’s no way to enable LC3/LC3+ via Bluetooth connection.

Hello. Any chance of comparison between this and the original ROG Cetra? Speednova is almost three times more expensive than the original, and I wonder whether they’re three times as good.
