The Audio-Technica ATH-SQ1TW2NC adopts a true wireless, in-ear design with no cables or neckband, keeping each earbud at a lightweight 8 grams. The earbuds carry an IPX5 ingress protection rating, confirming their resistance to water and making them suitable for use in wet conditions. Stereo speakers are built in, while features such as wingtips, RGB lighting, a UV light, and a display are not included in the design.
The ATH-SQ1TW2NC combines active noise cancellation with passive noise reduction to help block out unwanted ambient sound. Audio is handled by a 5.8 mm driver unit with a frequency response spanning 20 Hz to 20,000 Hz. The earbuds do not feature a neodymium magnet, and there is no support for spatial audio formats such as Dolby Atmos or Dirac Virtuo.
The ATH-SQ1TW2NC is equipped with a rechargeable battery that delivers 6 hours of playback per charge, with the charging case contributing an additional 12 hours for a combined total of 18 hours. A full charge takes 1 hour, and a battery level indicator is included to help monitor remaining power. Wireless charging and solar battery functionality are not supported.
The ATH-SQ1TW2NC connects wirelessly via Bluetooth 5.2 with a maximum range of 10 meters, and supports the AAC codec for audio transmission. Charging is handled through a USB Type-C port, though wireless charging is not available. The earbuds do not support fast pairing, NFC pairing, or Auracast, and none of the aptX codec variants — including aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, or aptX Voice — are supported. Bluetooth LE Audio and LDHC are likewise absent.
The ATH-SQ1TW2NC includes an ambient sound mode and a mute function, and it can be used as a headset for calls. Controls are placed directly on the earbuds, and voice prompts are available to guide the user, though there is no in-line control panel. The earbuds support multipoint connectivity for up to two devices simultaneously and feature fast charging for quick top-ups. A travel bag is included in the package. In-ear detection, notification readout, a built-in translator, a body temperature sensor, and a camera remote shutter function are not available.
The ATH-SQ1TW2NC features a noise-canceling microphone that covers a frequency range of 20 Hz to 10,000 Hz, allowing it to capture voice clearly while reducing unwanted background noise during calls.
