On 25 February 2021, the company announced Teenage Engineering as a founding partner, mainly responsible for the brand's design aesthetic and its products.

Investors in the company include Tony Fadell of iPod, YouTube personality Casey Neistat, and GV (formerly Google Ventures).

[7][8] On 25 February 2021, the company announced its first founding partner, Teenage Engineering, to produce the design aesthetic of the brand and its products.

[16] In February 2023, during the Mobile World Congress (MWC) in Barcelona, Nothing announced that their next generation of phones would be powered by the Snapdragon 8+ Gen 1.

Wired praised the detailed sound profile, distinctive design, and voice-assistant interaction, but criticized the treble reproduction, physical controls, and "so-so" noise cancellation.

[21] On 17 November 2023, Nothing released a messaging app that promised end-to-end encryption but was storing texts publicly in plaintext.

PCMag wrote that, "The Nothing Ear earphones offer better sound quality, longer battery life, and more Bluetooth codecs than their predecessors while maintaining an elegant, transparent design.

[30] It came with the MediaTek Dimensity 7200 Pro chipset running Android 14 and Nothing OS 2.5, a 6.7-inch 120-Hz OLED display, and a 5000 mAh battery.

Key upgrades include a MediaTek Dimensity 7350 Pro processor for smooth multitasking and better gaming performance, achieving impressive benchmark scores compared to its predecessors.

Both phones have AMOLED 6.77 inches 120Hz displays, both exist in 128GB and 256GB storage variants, both have the same 5000 mAh battery and the same Snapdragon 7s Gen 3 (4 nm) chip.

These new earphones support the LHDC 5.0 low latency HD audio codec and come equipped with 11.6 mm speakers, similar to its predecessor.

Despite a less powerful chipset, the Ear (a) provides a reliable user experience, offering customizable touch controls, in-ear detection, and similar levels of noise cancellation (up to 50 dB).

The announcement stated that Nothing Chats was developed by company called Sunbird and would have limited compatibility with Apple's iMessage.

Ars Technica explicitly advised readers against giving their Apple username and password to a company which might not "understand and/or respect the security version of Pandora's box they are opening".

[51] On 17 November, shortly after launch, a third-party developer discovered that the app was using a version of a rival open-source project called BlueBubbles but Sunbird failed to procure a TLS certificate so the application was sending users' service credentials via insecure HTTP.
