The Swiss Cougar Stuttgart Active Noise-Cancelling Bluetooth Headphones make an excellent general promotional item for businesses seeking a practical and appreciated gift. These noise cancelling headphones feature active noise cancelling technology (20db, 20Hz - 20kHz), which helps suppress external sounds for clearer audio. The headphones measure 18.5 (l) x 17 (w) x 8 (h) cm, constructed from aluminium, ABS, and PU for comfortable wear. Bluetooth version 5.3 provides a 10-metre visible range, with a 400mAh lithium battery offering approximately 20 hours of playback in Bluetooth-only mode. A protective EVA case, sized 18.5 (l) x 14 (w) x 8 (h) cm, is included for convenient storage and transport of the headphones. These headphones are ideal for branding on the aluminium ear cup plates or the EVA case, making them a visible and useful general promotional product.
