Audionic Signature S-350 | Specifications

Good audio should fit into daily life without demanding attention, and the Audionic Signature S-350 neckband does exactly that. It focuses on comfort, steady performance, and practical features that make sense for real users. Whether you spend hours on calls, stream music on the go, or play games on your phone, this neckband delivers a balanced experience without overcomplicating things. It looks simple, feels light around the neck, and comes in black, blue, and white so you can pick what suits your style.

Bluetooth & Sound

The S-350 runs on Bluetooth 5.4, which keeps the connection stable and quick. Pairing feels smooth, and once connected, it stays locked in without random drops. Inside, 10mm drivers handle the sound. They produce clear vocals and a solid low end that adds depth without drowning out the mids. This makes music enjoyable and voices easy to understand during calls or videos. Support for AAC and SBC also helps maintain sound quality across different devices.

Battery Life & Playtime

Battery life stands out here. You get up to 25 hours of playtime on a full charge, which easily covers several days of regular use. If you ever run low, a quick 3-minute charge gives around 3 hours of listening. That kind of fast top-up feels genuinely useful when you are in a rush. On standby, the neckband can last up to 250 hours, so it does not constantly beg for charging.

Comfort & ENC

Comfort plays a big role in neckband design, and this one gets it right. The build sits lightly on the shoulders, and the eartips fit securely without causing strain during long sessions. Magnetic earbuds snap together when not in use, keeping them tidy and reducing cable mess. The IPX5 water resistance rating means sweat and light splashes will not be a problem, which is good news for workouts or outdoor use.
Call quality also benefits from ENC, which reduces background noise and makes your voice clearer to the person on the other end. Gamers will appreciate Battle Mode, offering low latency between 40 and 60ms. Audio and visuals stay closely in sync, which matters during fast gameplay.

What's in the Box?

In the box, you get the neckband, eartips, a Type-C charging cable, a user manual, a feature book, and a warranty card. It covers everything you need to start using it right away, without extra purchases.
