About Pamu Slide II Tws Earbuds

Pamu Slide II is designed for simplicity. Innovative and smooth sliding experience. powered by dual Qualcomm flagship Bluetooth and digital independent active noise cancellation chipset, the total attenuation can reach 40db, which effectively solves the harms caused by noises. Users can switch between the pass-through function and active noise cancellation according to different scenarios whether in daily life or on business occasions. The in-ear detection function makes it more convenient for users to use.

Within the evolving landscape of personal audio technology, Xiaolu Cai's Pamu Slide II Tws Earbuds emerges as a distinguished example of contemporary industrial design that seamlessly integrates functional engineering with refined aesthetic sensibility. The composition presented here invites contemplation of form language in consumer electronics, where the designer has orchestrated a visual dialogue between the substantial charging case and its complementary earbuds through careful attention to material harmony and proportional relationships. The concentric circular motif adorning the case lid operates as both decorative element and conceptual reference, perhaps evoking the radiating nature of sound itself or the precision mechanics housed within, while simultaneously providing tactile orientation for users. Technical accomplishment manifests in the sophisticated surface treatments that balance light absorption and reflection, creating visual depth within what might initially appear as simple black forms. The sculptural quality of the earbuds themselves demonstrates considered ergonomic development, their organic contours suggesting extensive research into human anatomy and comfort requirements for extended wear. One observes the thoughtful integration of functional elements such as microphone apertures and charging contacts within the overall form, neither hidden nor prominently displayed but rather absorbed into the design language as natural surface variations. The presentation against an unadorned white field emphasizes the objects' volumetric presence while allowing subtle tonal variations to become apparent, revealing the care invested in finish quality and assembly precision. This work participates in a broader design tradition that values restraint, where visual impact derives from proportion, material quality, and formal refinement rather than applied decoration. Viewers might consider how such everyday objects shape our sensory experiences and daily rituals of connection through sound.

Press Kit

Unique Properties: This is an active noise cancelling true wireless earphones that effectively solve existing noise troubles. Powered by dual qualcomm flagship bluetooth and digital independent active noise cancellation chipset, the total attenuation of can reach 40dB, which effectively solve the harms caused by noises. Users can switch between pass-through function and active noise cancellation according to different scenarios whether in daily life or business occasions.
Dimensions & Packaging: earbud: width 18.5mm x height 28.0mm x depth 25mm,
charging case: width 69.5 mm x height 44 mm x depth 29.8mm. The total weight of the product is 55g, earphone 5.5g.
Tags: ANC, Slide, TWS earbuds, Noise-canceling earbuds, Wireless charger
Production Technology: Design optimization from more than 5,000 users' ear data to ensure snugly fit-in and comfortable wearing. The main material of the earbuds and charging case are injection-molded polycarbonate - Acrylonitrile Butadiene Styrene composite, which ensures the product to be lightweight with strength. Wireless charging allows users with more choices in different scenarios.
Design Challenge: How to collect and aggregate the ear data of thousands of users and distill them into a headset shape suitable for our target users is our biggest challenge. The second challenge is how to maintain the design details and texture of the product while maintaining the minimalist design style. We adopted the fading and LOGO raised silk screen hot silver process.
Project Duration: The project started in September 2021 in Xiamen, Fujian Prov., China. and will be released on September 30, 2022.
Operation Flow: Open the charger and pick up the headphones to achieve automatic pairing of the headsets at a second speed, simplifying user operations. qualcomm flagship bluetooth 5.2 technology ensures a fast and stable connection between the headset and any mobile communication device, while calling different voice assistants. Tap the touch button to answer the call or pause the music. when the headset is out of power or not in use, the charger is automatically charged and charged.
Research: Comfortable to wear, no movement, no signal, good sound quality. This is the 4 important elements of tws headphones. To this end, we have used Gras artificial ear and AP electroacoustic tester and RF tester and other first-class professional equipment, using the ultra-low power consumption of true Bluetooth 5.2, qualcomm aptX resolution sound quality, LDS antenna laser engraving, double wheat noise reduction, etc. Leading technical solutions. repeatedly measured and modified, and finally designed an earphone that is ergonomic, comfortable in the ear and not easy to fall off and has excellent sound quality.
Inspiration: Pamu Slide II is an active noise cancelling true wireless earphones. equipped with unique spoiler structure of front mic and six-microphone design, together with AMS chip algorithm technology, of which noise-canceling intensity could reach 40db, that effectively solve existing noise troubles.
