In June 2024, Beats launched a new TWS earbuds – Beats Solo Buds. It uses Beats’ smallest charging case ever, equipped with a fully customized acoustic architecture, compatible with iOS and Android systems, and has a single battery life of up to 18 hours.
Beats Solo Buds is equipped with a customized sound system and a double-layer driver unit design to minimize micro-distortion. By placing it in parallel with the acoustic nozzle filter, it can better transmit sound to the ear canal. The laser-cut ventilation holes further improve the audio performance. It adopts a clear and balanced tuning style to present a wide sound range and delicate music details.
Equipped with the custom-designed microphone and advanced noise learning algorithm, it provides clear call quality. Compatible with iOS and Android systems, it supports one-click pairing when used with Apple phones, tablets, and laptops, and automatically pre-pairs across devices. Android devices can control various functions through the Beats App.

03/ Summary
Beats Solo Buds adopts a very light and compact charging case design, which brings extreme portability. The translucent shell makes the look more trendy and fashionable. The earbuds continue the family-style bean-shaped design, and the body curve ensures comfortable wearing.
The charging case does not have a built-in lithium battery and is only equivalent to a charging stand, which needs to be connected to a power source to charge the earbuds. The earbuds are equipped with a 105mAh steel shell button battery, which provides 18 hours of battery life. Other configurations are mostly customized models, including a customized double-layer driver unit, MediaTek MT2827SA bluetooth audio SoC, and a MEMS microphone for sound pickup.
