Review of the JBL Tune 760NC: a sustainable level of Bluetooth headset access

Manufacture and accessories

The Tune 760NC is a very classic helmet that is completely composed of matte plastic shells of passable quality. The “cheap” aspect is further reinforced by the joints between the headband and the ear cups that are covered with a shiny plastic that will inevitably attract fingerprints. Some squeaks, at the level of the hinges, can also be heard, which does not guarantee the strength of the helmet. Fortunately, the shells of the ear cups are not “hollow” when tapped.

The earcups rotate 90 ° and can be folded inside the headband, making it easy to carry the headphones in a bag. However, we regret that no case was brought forward for the purchase. The faux leather pads appear to be of good quality and can be unclipped for possible replacement; a good point.

The USB-C port for charging is located on the top of the left ear cup, which is hidden by the swivel hinge.  A strange location though that doesn’t matter, as the helmet won’t work if it’s in control.

Below the right atrium, there is a series of buttons as well as a 2.5 mm sub mini-jack auxiliary input to operate the headphones passively. A relatively unique format that requires the use of cable is provided for this purpose. A USB-A to USB-C cable for 25cm charging is also included.

Comfort and support

The comfort feelings of the Tune 760NC are very divisive. On the one hand, the strongest heads can be damaged by the circular shape of the headband that incorrectly marries the morphology of the human head. This can lead to a focused area above the head, which can become uncomfortable over time. The stiffness of the headband can also exert a marked “pinching effect” around the ear, which can also be unpleasant during long listening sessions. On the other hand, even folded in the smallest, the headband is rather large and unsuitable for small morphologies.

But that’s not all; the shape and size of the ears can also influence feelings of comfort. The Tune 760NC can be a circum -auricular headset – the ear pads should cover the entire ears – but the inner space of the pads is very tight. So people with large ears can feel the pads in the ears and cause, in fact, some pain. Prolonged wear can also cause antihelix pain due to the lack of protective foam around the speakers.

The Tune 760NC can, on the other hand, be comfortable if you have the right head and ear size. The pads are comfortable and soft, the padding on the headband also does its job well. Also, even if it’s hard to forget the helmet because of the “clamp effect”, the Tune 760NC is lighter (220 g). It also benefits from excellent support.

User experience

Without an accompanying mobile app and advanced features, the Tune 760NC is straight to the point. So all the controls are placed under the right atrium, in the form of 5 mechanical buttons that give access to navigation between tracks, manage playback and calls, control the volume, trigger the assistant, pairing, switching, and of course activation. active noise reduction. The buttons quickly drop to the hand and the controls respond, but the click caused by each press is more pronounced. We also regret that there is no voice guidance available, although there are some tones still in place to better guide the user.

The Tune 760NC communicates via Bluetooth 5.0 and is compatible with the SBC and AAC codecs. The headset has multipoint connectivity and is compatible with Google Fast Pair for quick pairing with Android terminals. However, there is no presence detector or mode for listening to ambient sounds, which is often called “transparent” mode.

Audio

The Tune 760NC has a much louder signature sound, boasting of the bass and treble area, but is sadly burdened by a somewhat pronounced overall inaccuracy.

The main strength of this helmet is its flowing strength. The bass is well flattered and brings a percussive aspect and a welcome roundness to the overall rendering. This bass highlight though is done with severe bass damage, which translates into a slight lack of foundation, but above all at the expense of the lower mids, victims of slight overflow. This reduction in the lower mids is only slightly marked when active noise reduction is activated, but that does not interfere with the various bell concerns encountered in the headphones.

The remaining frequencies are as colorful as bass. This has resulted in a general respect for the stamps of many instruments. The snare drum hits sound very loud, the bass drum hits sound very dull, the cymbals have a “brittle” aspect, the guitars and brass have a more pronounced pinched aspect … The vocals are able to stand up nicely more, but they are clearly lacking. body, heat, which aggravates their nasal part.

This poor respect for stamps should also be attributed to the general inaccuracy in sound reproduction. From bass to treble, everything lacks detail, goodness and definition. The translation is very difficult and very lacking in naturalness. However, we can detect a very good extension of the intense treble that opens up the soundstage small, not very wide or deep.

And not the wired connection that saves the day. The signature sound of the headphones is even more marked by multiple colors giving the Tune 760NC a more dull rendering, with stunted bass and high mids.
