X11 Bluetooth wireless earbuds with 18mm driver speakers and touch control for iPhone, Android, and Windows devices, featuring a portable charging case with optional wireless charging and 200-hour standby time, available in black or white.
X11 Sky-free Bluetooth Earbuds: Touch Control Wireless Headphones with Portable Power Bank Case

The X11 represents a functional true wireless stereo (TWS) audio solution, designed for users seeking cord-free convenience across multiple devices. Its core specification of Bluetooth 5.0 ensures stable connectivity for calls and music on iOS, Android, and Windows platforms. The product distinguishes itself with a practical, large-capacity charging case that not only recharges the earbuds but also serves as an emergency mobile power source. With an emphasis on ease of use, features like automatic boot pairing and intelligent power monitoring simplify the user experience, while the inclusion of multiple ear tip sizes aims to provide a more personalised and secure fit for daily commutes, work calls, or leisure listening.
Features and Construction

The X11 earbuds integrate several user-focused functionalities supported by a specific hardware configuration. The construction prioritises a balance of compact size and declared feature set, resulting in a product defined by its technical specifications and material choices.
Material and Build
The primary structural material for both the earbuds and the charging case is PC (polycarbonate), chosen for its rigidity and impact resistance which contributes to product durability. The earpiece itself utilises rubber for the sleeves, providing the necessary flexibility for in-ear comfort and seal. Internal components include a welded 6mm diameter speaker driver per earbud and a silicon microphone (model 2036) for voice capture. The charging case incorporates pogo pin connectors for transferring power to the earbuds and contains magnets to secure them in place when stored.
Size and Practical Fit
Each earbud is notably compact, measuring 18mm in width by 22mm in depth by 24mm in height, with a light individual weight of 11 grams to promote wearing comfort. The accompanying charging case has dimensions of 85mm x 53mm x 33mm, making it pocketable. To address fit, the product is supplied with six rubber ear sleeves: two pairs in large, medium, and small sizes. This allows users to experiment and select the sleeve that creates the most effective seal in their ear canal, which can improve sound isolation and stability during movement.
Uses and Placement

The X11 is engineered for versatile audio applications, from personal entertainment to professional communication. Its compatibility profile and feature set support use in various environments, whether at home, in the office, or on the move.
Event or Professional Use
For professional contexts, the integrated silicon microphone and support for HD Voice and HFP/HSP Bluetooth profiles are geared towards providing clearer voice transmission during calls, conference calls, or online meetings. The stated 5-hour call time allows for extended discussions without frequent recharging. Features like intelligent call releasing (auto hang-up) and multipoint connectivity (where supported by the host device) can streamline call management for users who need to switch between tasks or devices efficiently during their workday.
Everyday Home Use
At home, the earbuds serve well for media consumption, such as streaming music, watching videos, or gaming, facilitated by the A2DP and AVRCP Bluetooth profiles for audio streaming and playback control. The 7.5-hour music playback time (at approximately 60% volume) covers extended listening sessions. The touch controls allow for easy management of music—playing, pausing, and skipping tracks—or adjusting volume without needing to reach for a phone, which is convenient during chores, workouts, or relaxation.
Benefits and Buying Value

The value proposition of the X11 centres on its practical integration of extended battery life, a multi-functional case, and broad device compatibility. These factors contribute to a product designed for reuse and daily utility without complex maintenance demands.
Reuse and Low Maintenance
The product is built for repeated daily use. The 2600mAh lithium polymer battery in the charging case provides multiple full recharges for the earbuds' own 60mAh batteries, significantly extending total usage time between case charges. The case's dual role as a mobile power bank adds utility for charging other small USB devices in a pinch. With no complex mechanical buttons (utilising touch keys instead) and a degree of ingress protection suggested by the listed 'waterproof' characteristic, the earbuds require minimal specific maintenance beyond basic cleaning and careful charging.
Why Choose This Product
A user might select the X11 for its combination of a high-capacity, feature-rich charging case and straightforward, touch-operated earbuds. The inclusion of optional wireless charging for the case (where selected) offers modern convenience. The comprehensive package—complete with cables, multiple ear tips, and necessary certifications (CE, FCC, RoHS)—means everything needed to start using the product is included. For those seeking wireless earbuds that prioritise long battery life via a power-bank case, simple touch controls, and compatibility with common phone and computer systems, the X11 presents a clearly specified option.
