O modelo adota uma abordagem muito mais criativa para a audição diária, combinando rádio FM, transmissão sem fio e interação direta com o som. Seu design imediatamente reconhecível, sua alça emblemática e acabamento cuidadoso fazem dela um produto único no universo das caixas de som Bluetooth premium.\u003cbr \/\u003eNa linha do fabricante, a OB-4 ocupa um lugar original: o de um objeto de áudio design, pensado tanto para o prazer da audição quanto para a experimentação. Ela retoma o espírito inovador da marca sueca, conhecida por seus instrumentos eletrônicos e aparelhos de forte identidade, aplicando-o aqui a um uso mais doméstico, mais portátil e mais universal.\u003cbr \/\u003e\u003ch3\u003ePara ouvintes exigentes, criativos e móveis\u003c\/h3\u003eA OB-4 é destinada àqueles que querem mais do que uma caixa de som auxiliar. Ela será perfeita para o usuário exigente que busca uma reprodução musical de qualidade em uma sala, cozinha, oficina, terraço ou espaço de convivência compartilhado. Seu formato compacto e alça facilitam o transporte, tornando-a uma solução ideal para audição portátil sem sacrificar a presença sonora.\u003cbr \/\u003eEla também atrairá perfis criativos, colecionadores de objetos de áudio singulares e amantes de rádio que desejam rever uma passagem ouvida alguns minutos antes sem frustração. Para uso em casa, em deslocamento ou em um ambiente semi-público, a OB-4 oferece uma experiência mais viva e intuitiva do que uma caixa de som conectada clássica.\u003cbr \/\u003e\u003ch3\u003eUma audição interativa, graves naturais e uma verdadeira personalidade sonora\u003c\/h3\u003eA função mais marcante da OB-4 continua sendo seu sistema \"magic tape\": uma gravação contínua de 2 horas que memoriza permanentemente o que você está ouvindo. Na prática, você pode retroceder em um programa de rádio ou faixa, modificar a velocidade de reprodução e criar loops instantaneamente. É uma forma fresca, lúdica e muito moderna de redescobrir rádio e música.\u003cbr \/\u003eNo aspecto acústico, a caixa de som conta com quatro alto-falantes personalizados, distribuídos em uma configuração 2 + 2. O objetivo não é apenas obter volume, mas uma imagem estéreo ampla e uma reprodução mais natural. Em vez de forçar artificialmente os graves, a Teenage Engineering aposta em um duto bass reflex otimizado e em um design interno sofisticado para produzir graves profundos, agradáveis e menos cansativos para a audição.\u003cbr \/\u003eA experiência do usuário também contribui fortemente para o charme da OB-4. Os controles com interação mecânica convidam a manipular o som com os dedos, especialmente através do botão de volume com acionamento direto e do botão giratório dedicado. Em termos de conectividade, a caixa suporta Bluetooth audio, Bluetooth Low Energy, rádio FM e uma entrada estéreo de 3,5 mm, permitindo fácil integração a usos variados, do streaming móvel à audição com fio.\u003cbr \/\u003eFinalmente, sua autonomia é uma verdadeira vantagem no dia a dia. Dependendo do uso, pode oferecer até 72 horas de audição em rádio FM, cerca de 40 horas em média por carga, ou aproximadamente 8 horas no volume máximo. Esse nível de resistência, aliado à sua alimentação universal integrada, reforça ainda mais seu interesse como caixa de som premium portátil, confortável tanto em ambientes internos quanto externos.\u003cbr \/\u003e\n\n\u003ch2\u003eEspecificações técnicas\u003c\/h2\u003e\n\u003cstyle\u003e@media(max-width:632px){table[data-wb-spec]{display:grid;grid-template-columns:minmax(0,1fr)
