Ausounds has launched its second major earphone product category into the UK with the AU-Flex ANC, a wireless noise-cancelling neckband model.

LA-based Ausounds has brought its flagship audiophile earphone model, the AU-Flex ANC, to the UK, after gaining a CES Innovations Award in the US.

Ausounds Launches High-Fidelity Wireless ANC Neckband Earphones With Planar Magnetic Drivers

AU-Hybrid Planar Magnetic Drivers

Ausounds’ bespoke Planar Magnetic Drivers have a large (8mm) membrane driver surface suspended between a dual magnet opposing motor system. The Planar Magnetic Driver crosses over to a traditional 10mm dynamic driver for low frequencies that, freed from the requirement to handle HF, has been explicitly designed to deliver bass.

Noise Cancelling Tech

Ausounds’ advanced ANC system has been designed to have the minimum impact on music reproduction and sound quality. While many ANC systems have a marked influence on the headphone/earphone’s frequency response, the AU-Flex remains faithful to the source music whether the ANC is switched on or off.

Ausounds Wireless ANC Neckband Earphones with Bluetooth

Bluetooth LDAC High-Resolution Wireless Connectivity

The AU-Flex ANC offers uncompressed wireless connectivity by using Sony’s LDAC audio technology. With up to three times the data transmission rate of basic Bluetooth wireless technology (990kbps vs 328kbps) LDAC operates without any down-conversion of Hi-Res Audio content up to a maximum bit depth and frequency range of 96 kHz/24 bit.

Audio Comfort & Convenience

Catering for a wide range of ear shapes and sizes, the AU-Flex comes supplied with silicone ear tips in three sizes to create a comfortable seal. The standard tip fitting on the metal-bodied earpiece opens up the option of third-party tips, should users prefer the extra sound-isolation of Comply tips for example, and the Flex’s soft rubber ear hooks remain comfortable even after hours of listening. The AU-Flex ANC is IPX5 waterproof so you can sweat worry-free and rinse off additional dust with a gentle water spray.

Extended Battery Life 

These earphones come equipped with intelligent magnetic clasps with an auto-pause function to stop and start your music with ease. These magnetic clasps are also useful for answering phone calls hands-free and save battery life when connected in standby mode. With the neckband design offering space for higher capacity batteries than Ausounds’ True Wireless earphones, the AU-Flex has 10 hours playback from a single charge with ANC switched on, extending to 15 hours with ANC off.
