TWS Earbuds stands for True Wireless Stereo Earbuds, a term describing completely wire-free in-ear headphones. The "True Wireless" designation emphasizes the absence of any physical cables, even between the earbuds, distinguishing them from partially wireless designs (e.g., neckband-style). Each earbud operates independently, connecting directly to a device (like a smartphone) via Bluetooth, often using one earbud as a primary receiver that relays audio to the secondary bud for synchronized stereo sound. Key features include portability, touch controls, voice assistant compatibility, and active noise cancellation (ANC) in advanced models. 

They are typically paired with a compact charging case that stores and recharges the earbuds, extending their battery life. TWS technology leverages Bluetooth advancements (e.g., low-latency codecs) for stable connectivity and high-quality audio. Benefits include convenience, mobility, and immersive stereo sound, though trade-offs like shorter battery life compared to wired alternatives exist. The market has grown rapidly, making TWS a dominant category in personal audio.
