Non . Elle sont très bien .ajoutez les embout isolent puis dans l'application jbl activer le mode bass.
Les seul problèmes je trouve que le son n'a pas assez de puissance. Plus de puissance sera été parfait pour avoir plus de puissance dans les bass.
Quand j'écoute une musique qui a beaucoup d'effet de bass j'active le mode bass .
Quand j'écoute une musique normal je passe en mode studio 🎙
Voci une musique que je recommande (EXTRÊME BASS TEST!!!! 8D AUDIO)
BONNE JOURNÉE !

Le son pour tout ce qui est vidéo et film rien à redire le son me paraît très bon.
Pour ce qui est des appels, aucun souci j'entends très bien ce qu'on me dit et on m'entend très bien. Je n'ai pas besoin de répéter pour me faire entendre.
Si je l'ai mis que 4 étoiles c'est juste que par moment lors des communications d'un écouteur à l'autre le son peut être décalé, au bout d'environ 10 secondes les écouteurs rétablissent le son correctement de même. Hormis ce détail je ne regrette absolument pas mon achat.

Pós:
- O isolamento não é perfeito, porem não acho ruim. Nota 7/10.
- Qualidade do som. Nota 9/10 ( o fone parece baixo, porem da para configurar o equalizador direto no app JBL).
- A caixinha do fone não é grande e o fone em si é confortavel na orelha. Nota 10/10
- Microfone não é tão ruim, as pessoas consguem me escutar quando estou falando no em ligação. Nota 7/10
Contra:
- Tem um atraso significativo que me incomoda muito quando estou assistindo algum video. Nota 3/10.
- As vezes quando estou escutando musica acontece alguma interferência e estoura o som e quando isso acontece quase fico surdo dependendo da altura que estou ouvindo a musica. Nota 0/10.
- Não sinto que a bateria dura 32 horas como prometido, pelo menos a cada 3 dias tenho que carregar a caixinha (nunca fiz um teste a risca, porem eu so uso o fone no trajeito do caminha da minha casa para o trabalho o vice versa). Nota 6/10.
Avaliação total: Nota 6/10.
Esse fone so compensaria se fose uns R$150,00. Por isso não recomento
Comprei ele, pois eu vi muita gente falando que era um fone bom e intermediário, porem existe outros fones mais barato tipo Baseus W04 que está uns R$190,00 +/- e entrega uma qualidade otima pelo valor.
