Comfort, sound immersion and durability, these are some of the headphone’s attributes JBL Tune 770NC. Want to know more? Just keep reading.
Design
The headset Bluetooth da JBL Tune 770 NC It has a simple and discreet look that does not impress at first glance. The design choice seems more concerned with working on aspects such as comfort and practicality than visual sophistication.
We received the model in Black tone, but the phone Bluetooth It can be found in Blue and White colors.
Its body is made of a lightweight, matte plastic housing and padding on the top of the headband that surrounds the head. The two sound outputs are large and robust and have the company logo. JBL in shiny plastic that highlights the brand well.
Just by holding the phone in your hands you can see what it was made for: providing comfort. The grip is super light and soft and the headband, in addition to having height adjustments, also allows the sound outputs to be rotated to make it easier to store the headphones in your bag or backpack.
The sound outlet foams are dense, soft and super comfortable. I wear glasses, so depending on the headset it can press on my head and cause pain, but that wasn't the case, the foam on the JBL 770NC It hugs the ears and any accessories well without causing discomfort, I really liked it.
The phone has power, volume, Smart Environment that reduce external noise and the button that enables and disables calls, mutes the microphone and enables BixBy assistant, Crab and other voice assistants.
O JBL 770NC still has entry P2 to connect the phone via cable to the computer, tablet or cell phone and input USB-C for battery charging. All buttons and inputs are discreetly arranged at the bottom of the right speaker.
Audio
The sound of JBL 770NC It is loud, powerful and with little noise, I found the balance between bass and treble to be very well constructed and the sound leaks almost nothing to the external environment when it is positioned on the head.
the phone Bluetooth has been equipped with powerful 40 millimeter drivers, with a dynamic frequency of 20 Hz to 20 KHz, which means that the JBL 770NC reaches the entire spectrum of human hearing. It also reaches up to 100 dB (decibels), with 86 dB being the most recommended by WHO for quality audio that doesn't harm your ears.
Noise cancellation
Of course, we still need to highlight the strongest point of this headset, the adaptive noise cancellation technology known as ANC (Adaptive Noise Canceling). As previously stated, the Tune 770NC It has a button at the bottom of the right sound output that enables and disables this function, but the construction of this headphone alone easily disconnects you from the external environment.
In addition to noise cancellation working very well, we also have features such as Environment Aware which helps keep the user more aware of what is happening around them and the TalkThru, which decreases the phone volume by 20% when pressing the call button, which can be activated in the application JBL Headphones and they refine the sounds or voices in the environment by cleaning them well and providing greater sound immersion.
Microphone
The headphone focus was well away from the microphone, as I found the volume pleasant, but unfortunately noisy and with a slight imbalance between bass and treble, the sound is understandable and loud, but could have better definition. I consider this microphone to be very reasonable.
Bluetooth
O JBL TUNE 770 NC o Bluetooth 5.3 with LE audio, latest version. The technology optimizes audio quality based on the LC3 codec, enabling quality audio transmission with less delay, greater bandwidth, energy savings, with greater security and signal stability.
The version contained in this headset JBL promises connection up to 240 meters in free space, of course it was not possible to carry out a test at this distance, but I managed to stay more than 10 meters away from the audio source (my smartphone and later the computer) without loss of connection or apparent delays, including I was able to make calls from this distance.
It is possible to connect the device to the smartphone application JBL Headphones and stream high-quality audio BL Pure Bass Sound, which enhances the beats and increases the immersion of the sound. The application also has a feature Smart Audio & Video which improves sound quality or adapts for optimal video and gaming output. I found it very interesting and the integration between Tune 770NC and cell phone works very well.
Battery
the phone JBL Tune 770NC It has a rechargeable battery via a USB-C cable that promises 70 hours of music playback with ANC off, 44 hours on ANC plugged in, 39 hours of talk time and 70 hours of battery life in games, in addition, the brand promises 2 hours of plugging in to reach a full charge.
The cool thing about this is that I spent 3 weeks with the headphones using them for all my work and leisure tasks, listening to music, watching movies, going to the gym, etc. I had to plug it in for the first time about 7 days after the first charge and then I charged it again 5 days later.
Conclusion
O JBL Tune 770NC it's a headset Headset light and intelligent that delivers a great sound experience, leaving you completely aware of the external environment even without the function ANC enabled. Its bass and treble are very well balanced and the sound is just right.
Furthermore, the headset is extremely comfortable and does not present any discomfort even after hours of use, sometimes I even forgot to have it on my head.
In short, it is a headphone built to deliver an immersive and quality sound experience and it did what it promised.
As for the price, certainly the value of R$499 at the official store JBL It's really worth it, it's a very well built phone and the material, despite being plastic, doesn't appear to be fragile, if taken care of properly it can be an investment for years.
