JBLLIVE 670NC Wireless On-Ear Headphones with True Adaptive Noise Cancelling Wireless Over-Ear Headphones, Pure Bass Sound, Smart Ambient, Bluetooth 5.3, Le Audio, VoiceAware, 64H Battery, Beige

I have purchased these headphones for my everyday office usage, mostly for long meetings. I've also connected these to my phone so using with my laptop and phone in parallel without any issues. The sound quality is great. Built quality is excellent. The feeling on the head is a bit tight which may be due to being new and will adjust with time.I did some research before buying and I would say that JBL 660NC is the best headphones with this price tag.

Overall quality product.Easy to set EQ through App.Exact Overhead Fit.Ultimate ANC.

Quality is good, but it's bit to on my ear 👂

Excellent sound quality for such relatively inexpensive headphones. Very good bass audio reproduction in particular.

I really like the timely delivery, packing and the quality product.

Love the fit, the noise cancelation feature and everything about it. Highly recommended!

Quality product

I bought JBL Live 660NC based on many reviews, which was a mistake!TL;DR: Good sound and look from the outside, TERRIBLE experience once you use it!Pros:====1- The sound is good. It's not flat as some claimed, yet you can control the EQ from an app2- The overall build is not bad, and looks stylish3- It provides a decent amount of sound isolation4- It's comfortable to wear5- Price is ok for a JBLAll of these deserve one star when considering the cons!Cons:====1- Buttons are placed in such an annoying way that you can accidentally press them while adjusting the headphones2- The buttons places and functions are not intuitive, you need to actually learn what it means to single click, click and hold, and double click each one!3- Sound is a bit low, and on it's top volume level the bass gets a bit straining4- You need to connect it manually to each device whenever you switch to another one! (Is this even 2020's?)5- When connected using the cable, there's a delay between the source and the sound!!6- It's doesn't provide any breathing for the ears, so it feels warm in an uncomfortable way after a while. Even worse, it causes pressure on your ear that you feel after removing it!7- Battery life isn't that greatI prefer my AT-M50X 100 times more than this. Unsatisfactory buy

Bom, o fone em si é muito bem construído, material parece ser de qualidade e que irá durar. Provavelmente como em todos modelos que possuem couro na almofada ela deve esfarelar com o tempo. Volto pra dizer quanto.Ele é leve e apesar de no início aparentar que vai apertar a cabeça, não foi o meu caso. O arco talvez te incomode se for careca.A respeito da qualidade sonora é um JBL, portanto dispensa apresentações. Único ponto que talvez não agrade a muitos é que seu volume alto não é lá tão alto. Pode ser que possa afetar alguns. Não foi meu caso.Graves muito bons e agudos OK.O cancelamento de ruído é bom, mas já usei fones mais baratos com a mesma proposta ou até melhor. Não sei se é defeito do meu mas aleatoriamente ele da uns pequenos estalos no microfone do NC. Nada que me incomode.O aplicativo da JBL é bom e prático. A mudança pra diminuir a latência é bacana, mas consome mais bateria.A bateria tem duração excepcional. Carreguei ele 2x em um mês de uso moderado.Não recomendo que compre se for usar pra ter Alexa ou outro assistente de voz. Vive apresentando problemas de conexão.Fora isso, ótimo fone pra jogar, ver filmes e séries, fazer videoconferência, ouvir música.

Excellent sound quality

Parfait ! Il est conforme aux attentes de mon ami. Il l’utilise pour tout et le son est de qualité. Livraison rapide et bien protégé pour le transport. Je recommande.

Un son incroyablePresque dans la quatrième dimension

Je ne peux plus m'en passer. Je l'utilise pour écouter de la musique mais aussi pour regarder les films. Et aussi comme boule caisse quand les voisins sont trop bruyant.
