When used regularly at a moderate volume, kept in a single location, and protected from power surges, Bose soundbars (and any other speakers, for that matter) can last for decades. In the case of a device like a soundbar, which can feature modern connection interfaces, wireless compatibility, and state-of-the-art tech like Dolby Atmos, the products are technically at higher risk of becoming obsolete over time than simply ceasing to function.
