Review Bluetooth Tone LG Tone Free FN6: self-cleaning technology and timid sound [análise/vídeo]

O Tone Free FN6 is the new true wireless headset from LG launched in Brazil in December. The wearable not only boasts a Meridian signature, but also features a self-cleaning technology that eliminates 99.9% of bacteria. But not only that, the company promises up to 18 hours of playback with the case and noise cancellation. Does it please?

If you like the Tone Free FN6, prepare your pocket, as we are talking about a handset considered premium by LG and that has a suggested price of R $ 1,200. I used the device in the last few days and I share all the details in this review.

O Tecnoblog is a technology-independent journalistic vehicle that helps people make their next purchase decision since 2005. Our product reviews are opinionated and have no advertising intent. For this reason, we always transparently highlight the positive and negative points of each product.

No company, manufacturer or store has paid the Tecnoblog to produce this content. Our reviews are not reviewed or approved by external agents. The Tone Free FN6 was provided by LG by donation. The product will be used in future content and will not be returned to the company.

Design, comfort and case

The first impressions of the Tone Free FN6 were positive. I really liked the minimalist and delicate design that LG adopted; the white version further reinforces these characteristics. In addition to the look, comfort is another highlight. If you need to spend hours straight with your headphones on to work, know that the Tone Free FN6 has this advantage.

In the packaging, LG sends three pairs of tips of different sizes and, according to the company, they are made of non-toxic and hypoallergenic silicone.

The case not only serves to power the batteries, but it is also useful for keeping the headphones clean, literally. They have a technology called UV Nano, responsible for cleaning the devices inside the case.

It works like this: when you store the headphones, the ultraviolet light present in the case can eliminate 99.9% of the bacteria that are in the product. But this does not happen instantly, I talked to Ramiro Neto, who is a product manager in the Audio and Video area at LG Brazil, and he explained that the Tone Free FN6 needs to stay in the case for ten minutes to do the cleaning properly .

In addition, the case must be connected to power via the USB-C port available on the accessory, otherwise it will not work.

And as we are experiencing a pandemic, the Tecnoblog asked if the technology is capable of eliminating the coronavirus, but LG does not enter into this subject and only reinforces that the UV Nano can kill germs and bacteria in the mesh of the speaker of the headphones. I also found that, in other countries, the company also does not address this important detail.

It is good to emphasize that the ultraviolet light is invisible and the blue LED that lights up when you open the case is there “for aesthetic purposes only”. That is, in practice, the user will have no information about cleaning, even in the official application.

Features and connectivity

For a more complete experience, LG offers the Tone Free app, for Android and iPhone (iOS). While I was testing the product, the app was in English, it is not possible to change the language, but LG has already said that a Portuguese version will be released.

The app has a very simple interface and concentrates the main features and settings on the home screen. In it, the user can activate the ambient sound mode, configure the touch controls of the headphones, make adjustments with the equalizer and locate the gadget.

I found a feature available for reading notifications very interesting. When you activate this option, the headphones start to read messages and other information that arrive on the cell phone, which is very useful if you are walking on the street, for example, and you cannot take the device out of your pocket.

As it works with Bluetooth 5.0, the communication with the smartphone is very firm and the Tone Free FN6 starts to pair automatically as soon as you open the case after the first contact. During the evaluation, I did not notice high latency that compromises the consumption of games and videos.

Sound and battery quality

The sound of LG Tone Free did not please me at first due to the absence of bass and dry treble, which, consequently, make the songs very muffled. It is also possible to notice distortion in warmer parts of some songs when the volume is high.

In Can’t Stop, by Red Hot Chili Peppers, the vocals and some instruments sound clear, but the headphones tend to value the middle and especially the treble. You have the freedom to make adjustments, but the Meridian presets in the app were not enough to “fix this”.

In pop, FRIENDS, from Marshmello, the situation was opposite and I felt the song much more present, which made me realize that the gadget works better with this genre and the same goes for agitated electronics, like Burnin, by Calvin Harris, which sounded good with control and no noise.

But the beats are still in the background and can gain a little more breath by activating Meridian’s “Natural” or “Immersive” modes. This second preset does not quite deliver the same three-dimensional sound experience found on more expensive headphones, but it can be interesting in some situations.

Noise cancellation does not completely eliminate the noise of a truck, bus or motorcycle, but it does reduce the sound of a TV with volume by 20% or a microwave. The blocking of external noise is more related to the fit of the headphones and that is why LG highlights the ambient sound mode more, to hear what happens around you through the microphones.

Regarding the battery, the Tone Free FN6 is not to animate in autonomy and is below expectations. The brand claims that the headphones can last six hours of playback, but I was able to listen to music for 5h16min with the ambient sound off – at least a quick charge of 5 minutes guarantees another hour of battery life. Accompanied by the case, you still get 12 more hours.

LG Tone Free FN6: is it worth it?

The LG Tone Free FN6 is a phone that stands out more for its great differential: self-cleaning technology. Still, it is a pity that consumers are left without access to information and hygiene processes that could be available in the application.

In the main point, I missed a fuller sound, the bass present and the clearer treble. And the details are only noticeable in pop, while in rock you may be disappointed.

Despite this, the company nailed the construction. The headphones are IPX4 certified, sophisticated in appearance, light, comfortable and the case follows the same path. Connectivity is another highlight and the app has a great interface.

But I would not pay R $ 1,200 on Tone Free FN6, since it is possible to find better options for less. Note the Samsung Galaxy Buds + which costs R $ 700 and delivers much more battery; the Sony WF-1000XM3 is also available at retail for R $ 1,200 and has active noise cancellation and better sound.
