A nickel metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium. NiMH batteries can have two to…[Leggi tutto]

Wired Earphones receive an analog signal, which can handle more data than Bluetooth®. Therefore, it offers better sound quality. Ubiquity: As long as there’s a 3.5mm input, wired headphones can connect to any audio source, from your dad’s Walkman to your brand-new laptop.

The neckband earphones allows for a combination of features you rarely…[Leggi tutto]
