Earbuds to sharpen hearing

If hearing is a problem, especially in loud environments, you could do yourself a favour with Lizn’s Headpiece earbuds. The Danish startup, Lizn, has developed one solution with its Hearpieces wireless earbuds, which, although not designed to be hearing aid replacements, are ideal for people who have minor hearing impediments and want to boost their hearing ability in different environments. The discreet earbuds adjust the ratio of close speech to background noise, amplifying the former and deadening the latter.
