The OneOdio Fusion A70 Gen 2 over-ear headphones improve upon the original with enhanced audio reproduction, a wider soundstage, wireless multi-headphone audio sharing, and dual 3.5/6.35 mm wired inputs. They can use the Hi-Res Audio LDAC codec for high-resolution music playback over wireless connections.

The OneOdio Fusion A70 Gen 2 over-ear headphones have debuted with improved sound reproduction and expanded wired and wireless connectivity for high-resolution music enthusiasts, DJs, and music creators. The foldable headphones come with an improved headband and contact design for greater comfort.

The Fusion A70 Gen 2 utilizes 40 mm dynamic drivers coupled with independent acoustic chambers to reproduce music across a frequency range of 20 Hz to 40 kHz. The second-generation headphones have been designed for a wider soundstage with greater audio depth, according to the company.

The headphones have a wired impedance of 32 ohms and a sensitivity of 112 dB when connected using the built-in 3.5 mm (1/8-inch) and 6.35 mm (1/4-inch) jacks. The 3.5 mm jack supports the use of compatible locking cables to prevent accidental detachment when used for DJing.

The OneOdio headphones also support Bluetooth 5.0 wireless connections with up to two devices at once. Multiple users of the Fusion A70 Gen 2 can listen to the same wireless audio source simultaneously using SharePort music sharing.

The headphones support the LDAC Hi-Res Audio codec, enabling high-quality music transmissions from Bluetooth audio sources, like this Fiio Snowsky DAP (sold on Amazon). Listeners can further refine the sound using the OneOdio smartphone app, which comes with presets and custom EQ options.

When used wirelessly, the Fusion A70 Gen 2 has a rated runtime of up to 72 hours, with a two-hour recharge time, according to OneOdio.

The Fusion A70 Gen 2 is available for $59.99 from the OneOdio store on Amazon or the OneOdio website.
