Features and Construction

The TW40 headphones are built around core electronic components that support reliable pairing and audio performance. The following sections break down the key materials, battery specifications, and practical controls that define this product.

Material and Build

The headphones use a high quality true copper ring speaker, which is a common choice for budget-friendly wireless earbuds aiming for decent sound reproduction. The true stereo chip handles audio processing and synchronisation between left and right earpieces. The charging case is made from plastic and houses a 400mAh pure cobalt battery with an integrated IC protection board to manage charging safely. The earpieces themselves contain 50mAh pure cobalt batteries. The entire set weighs 140g, and the packing box measures 10 x 10 x 4.2 cm.

Size and Practical Fit

Exact earpiece dimensions are not provided, but the total weight of 140g indicates a compact, lightweight design typical of in-ear wireless headphones. The charging case is similarly pocket-sized based on the packing dimensions of 10 x 10 x 4.2 cm. The fit should suit most ears for casual use. Colour options are limited to black or white, which match a wide range of personal styles.

Uses and Placement

The TW40 headphones are designed for everyday use where Bluetooth audio is needed. The following sections outline common scenarios for their application.

Event or Professional Use

A 15-20 metre non-obstructed range allows freedom to move around a small office or meeting room while staying connected to a phone or computer. The HD binaural call feature supports clearer conversations, useful for remote work or conference calls. The touch-based controls let you answer or hang up with a single tap, and you can adjust volume or skip tracks without reaching for the connected device.

Everyday Home Use

At home, the TW40 headphones work well for listening to music, podcasts, or watching videos on a phone or tablet. The charging case keeps the headphones powered throughout the day, with a standby time of over 30 days when not in use. The auto-shutdown feature after 3 minutes of inactivity helps save battery if you forget to turn them off manually.

Benefits and Buying Value

The TW40 headphones offer straightforward wireless audio at an accessible price point. The following sections highlight the practical value they bring.

Reuse and Low Maintenance

The 400mAh charging case can recharge the headphones multiple times before needing to be charged itself via the included USB cable. The pure cobalt batteries are a standard type for small electronics, and the IC protection board helps prevent overcharging. Manual controls for play, volume, and track skipping are simple to learn and do not require a separate app.
