LG Tone Free FN9A Bluetooth, Noise-cancelling earphones (review)

It does not get much better than the LG Tone Free FN9A ‘buds’. Great sound, decent noise-cancelling, good battery life and even a built-in UV Nano steriliser.

First, a brief explanation of our review procedure. We test over two days of use – battery life is an extrapolation of that. We can’t measure absolute volume and frequency response – only tell you if it sounds good with our test tracks. So, Cybershack uses a consistent comparative chart approach (same for each bud tested) that allows you to compare different buds on an ‘apples for apples’ basis.

Sound – Superb

Bass is quite punchy, treble is there for crisp high notes, volume is good, the sound stage is outside your head, and the buds have a fairly neutral sound signature, so the EQ works well.

We like the Bass Boost, but the 3D spatial became our usually listening favourite. Two custom EQ modes allow you to create your sound signature. We experimented with a 1-4kHz boost for clear voice, perfect for TV listening.

Try the Dolby Atmos test and Manhattan Transfer in our guide How to tell if you have good music (sound signature is the key).

ANC, Ambient noise and conversation modes

Not quite as high a level as Sony or Bose, but it allows LG to have a more expansive sound stage. In all fit for the purpose and fine for work from home or office use.

Ambient mode lets about 70% of the noise in and conversation 100%.

Battery life

All claims are at 50% volume, and we find that 70-75% is more appropriate. We got 4 hours and 47 minutes ANC on at that volume.


The only caveat here is to get the right gel cap fit for effective ANC. This also ensures they stay in during exercise (IPX4 sweat-resistant). I like the small POD stalks (I hate dorky Apple PODS) – they are practical handles to insert the buds and have a beam-forming mic in each for hands-free.

Unique features

UV Nano disinfects your ear tip with UV light. It does not clean or remove ear wax. The AUX-in is surprisingly useful to listen to music from 3.5mm devices like a PC or aeroplane.

CyberShack view – LG Tone Free FN9A are premium buds

No, they are not the very best – let Sennheiser (Momentum), Sony (WF1000xM4) or Bose (Quite Comfort) argue over that spot, but for the money, LG FN9A offer good value and useful features above the other premium buds. They get our tick of approval.
