LG Tone Free HBS-FN6 is simple and stylish True wireless headphones. They cost $150 and can compete with many of our favorites in this category and provide some unique selling points, such as UVnano boxes, which can kill bacteria on the earpiece when charging. The driver can reproduce some serious bass depths, but they are dominated by the sound characteristics and by default do not highlight their intensity. Thankfully, a companion app has customizable EQ, so you can customize audio to your liking and draw the best sound from the driver. In other words, this is a very crowded area, and in terms of audio performance, these in-ear headphones are not very good.


Silent HBS-FN6 earpieces are available in black or white models, AirPodShaped stem, each ear is equipped with capacitive touch control. They come with three pairs of hypoallergenic silicone earplugs (S, M and L, respectively), and the fit is very strong.

A USB-C charging cable of sufficient length is included, which is connected to the back of the small round charging case. The box has a reversible lid and a blue “mood lighting” (wording in the manual) inside. The interior is also equipped with UVnano technology, which can kill bacteria when the headset is charged, which is indeed a unique feature.

One IPX4 rating It is decent, but not impressive. This means that the earpieces can withstand slight splashes and can also be wiped with a damp cloth, but exposing them to heavy rain or the pressure of a tap may cause trouble.

On-ear controls are responsive and are reasonably divided between ears. (You can also change the content assigned to each ear in the app.) In the default mode, you can play/pause/answer or end the call with just one tap of the ear. Double tap on the left ear to decrease the volume or increase the volume on the right ear. Double-tap on any location to skip tracks, but you can assign the left side to navigate backwards. Long press to enter or exit the environmental listening mode, which can be controlled by the faders in the app to mix the sounds around you, so you can easily make calls without changing the headset.

The LG Tone Free application is available for Android and iOS devices. In addition to the Ambient Sound fader, the app also features multiple EQ presets designed by Meridian (UK luxury audio manufacturer), and user-definable EQ presets, of which eight frequency bands can be used to enhance or cut, and then save. The headset is compatible with Bluetooth 5.0 and supports AAC and SBC codecs.

LG estimates that the battery life is about 6 hours, in this case it will charge another 12 hours, but your results will vary with the volume.


In the audio test, we switched the headset to a user-definable EQ preset, and then set all eight frequency bands to zero to achieve the flattest response. We also tested with various EQ presets, such as Bass Boost and Natural. Bass-enhanced sound… strange. Both bass and treble are enhanced, but the meridian is also here to deal with stereo imagery-perhaps adding a spatial effect. The same is true for immersive mode. You may hear some sounds on some songs, but you can completely change the mix of other songs. Except for the “natural” mode, these modes sound unreal.

The strange thing is how different the natural mode sound is from the flat default preset after setting all EQ faders to zero. In this case, the mix sounds a little dull compared to the natural preset, so, anyway, to get the best results from the drive, you need to get a little EQ.

How do we test headphones

On tracks with strong bass components such as The Silent Shout of The Knife, the headphones provide a strong low-frequency response without distortion at unwise listening levels. Bass boost mode-or custom EQ with more bass-will definitely attract booming bass enthusiasts, but in flat response mode, there are many low-end products.

The depth of bass in Bill Callahan’s “Drover” mix is ​​much smaller, giving us a better understanding of the general sound characteristics of Tone Free HBS-FN6. In the absence of enhanced bass, the drum on this track sounds relatively mild-not thin, but it certainly does not thunder. Callahan’s baritone vocals have increased the richness of some low-end, but there are also many mid-range. Generally speaking, this is a balanced sound feature. Like the low-key part of the mix, more attention is paid to brighter elements, such as the acoustic column, which may be biased toward the low end without strong bass. Move forward. The treble is significantly improved, so the hiss of recording and the bright percussion take a step forward in the mix.

In Jay-Z and Kanye West’s “No Church in the Wild”, the midrange and treble of the foot drum loops are less than we have heard before, reducing the difficulty of their blows . However, the vinyl cracks and hiss in the background are moving forward, so there must be some precise engraving in the treble. The double bass synthesizer that hits the beat is delivered as a solid thump in flat mode. Switching to Bass Boost mode has a lot of ridiculous things about this hybrid approach. The strange thing is that it is simply called Bass Boost. Even if the bass is turned off, the bass actually sounds better.

Orchestra repertoire, such as the opening ceremony of John Adams Another Mary’s GospelIt sounds a little bass boost and dull in tablet mode. This seems to be an overall trend, so my suggestion is to create a custom EQ preset in the app to improve high midrange and deep bass, if you want some extra bass effects. Ultimately, no matter which mode you are in, a lot of DSP (Digital Signal Processing) will occur, and adjusting in one of the non-meridian EQ presets is the best choice for some kind of realistic mixing. Drivers can of course provide deep bass and crisp treble, as well as various mixed sounds between the two, which is entirely up to you.

The microphone has average clarity. Using the Voice Memos app on the iPhone 8, we can understand every word recorded, but the typical Bluetooth distortion adds blur to the edges of the words, and the microphone signal sounds faint. This is typical of true wireless in-ear microphones. Although it may not be a selling point, the clarity of the microphone is sufficient for phone calls.

in conclusion

In terms of price, LG’s Tone Free HBS-FN6 headphones have an elegant design and some unique features, especially the sterilization box. But the audio experience is a bit strange, the presets often sound a bit off, and the default sound characteristics are not ideal. Some EQ adjustments can achieve better audio performance, but this requires you to do some work. For a similar price, we prefer the sound of $150 JBL UA true wireless flash memory And $180 Jaybird Vista, Both are fully waterproof. To get more money, we like $200 Jabra Elite Active 75tAnd Anker’s Soundcore Liberty Air The headphones don’t have any decoration, but the sound quality is pure and only costs $80.
