Original wholesale carton information is retained for reference: 62.5 × 36 × 56 cm, stated volume 0.126 m³, gross weight 14 kg and 300 units per carton. These are supplier shipping-carton specifications, not the quantity included in an individual retail purchase. ![Supplier earphone driver illustration](https://cdn.shopify.com/s/files/1/0715/8595/6114/files/exstock-kp238-detail-13-20261109.jpg?v=1794243574) ![KP-238 black and silver earpieces close-up](https://cdn.shopify.com/s/files/1/0715/8595/6114/files/exstock-kp238-detail-14-20261109.jpg?v=1794243574) ![KP-238 earphone fit illustration](https://cdn.shopify.com/s/files/1/0715/8595/6114/files/exstock-kp238-detail-15-20261109.jpg?v=1794243577) ![KP-238 USB-C earphones with supplier 10 g weight label](https://cdn.shopify.com/s/files/1/0715/8595/6114/files/exstock-kp238-detail-16-20261109.jpg?v=1794243578) ![KP-238 specification panel showing driver connector and sensitivity](https://cdn.shopify.com/s/files/1/0715/8595/6114/files/exstock-kp238-detail-17-20261109.jpg?v=1794243578) ![KP-238 cable specifications and retail packaging](https://cdn.shopify.com/s/files/1/0715/8595/6114/files/exstock-kp238-detail-18-20261109.jpg?v=1794243578) ### Why Shop With EX-STOCK Canada EX-STOCK Canada works with vetted suppliers and manufacturers.

Universal compatibility is not verified. Check that your exact device supports USB-C digital-audio earphones; microphone and button functions can also vary. #### Do they have a microphone and volume controls? Yes. The specifications list a microphone and inline controls for calls, playback, track selection and volume. Supported functions depend on the connected device and app. #### How long is the cable? The cable is listed as 1.2 m long, with a TPE covering and 32-core oxygen-free copper wiring. #### Are these noise-cancelling or certified waterproof? No active noise cancellation or verified water-resistance rating is established. General supplier promotional icons should not be treated as certification for this model. #### Are they guaranteed low-latency gaming earphones? No measured latency or gaming-platform compatibility is available. They are wired earphones; gaming performance is not guaranteed. ## Details - **Price:** 16.99 CAD - **Vendor:** EX-STOCK - **Type:** USB-C Wired Earphones ## Variants | Variant | Price | Available | |---------|-------|-----------| | Black | 16.99 CAD | In stock | ## Images - KP-238 black USB-C earphones showing earpieces inline remote and connector - KP-238 USB-C earphones with retail packaging and supplier specification panel - KP-238 wired earphones product illustration with inline controls - Person wearing KP-238 semi-in-ear wired earphones - KP-238 earpiece close-up with 14 mm driver and 1.2 m cable labels - KP-238 wired earphones with black cable and silver-coloured USB-C plug --- > Source: [EX-STOCK Canada](https://www.ex-stock.com/products/kp-238-usb-c-wired-earphones-with-mic-inline-controls) > Updated: 2026-11-10
