Com o USB-C como norma universal, os fabricantes estão a criar ligações digitais que dispensam a entrada analógica e suportam áudio de alta resolução. Melhores conversores, sinal mais limpo. Na Ásia já é uma febre. E os números do mercado, os lançamentos de produto e as grandes aquisições confirmam a tendência.]]></description><link>https://www.cristinacosta.online/post/o-cabo-dos-auscultadores-est%C3%A1-a-voltar-e-desta-vez-chega-pelo-usb-c</link><guid isPermaLink="false">69d76e30fc7a52acb9097cdd</guid><category><![CDATA[Auscultadores]]></category><pubDate>Thu, 09 Apr 2026 09:23:21 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/5a30ad_a68dfdea6ea64a82bfc933b9f6d5257d~mv2.jpeg/v1/fit/w_1000,h_1000,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>Cristina Costa </dc:creator></item><item><title><![CDATA[The wire is making a comeback.

A IA funciona melhor em tarefas simples e repetitivas, libertando tempo para que os assistentes humanos se concentrem nos casos mais difíceis. O desafio não é substituir pessoas, mas usar a IA para lhes dar melhores respostas e mais contexto, em vez de as afastar dos clientes.

Over the last few years, audioXpress has been showing how fast we’re moving from “better headphones” to brain‑sensing audio devices – from AAVAA’s accessibility headbands to Naqi’s neural earbuds and IDUN’s in‑ear EEG.

I pulled together a few of these articles and some recent neurotech developments to map where audio and neuroscience are converging in 2026 – and why it matters for anyone working in media, product or digital content.
