LG Tone Platinum HBS-1100 Stereo Bluetooth Headset – Review – The Worlds First with APT-X High Definition


Welcome to my review of the LG Tone Platinum HBS-1100 Bluetooth Headset. This is the world’s first pair of headphones/headset that comes with the new APT-X High Definition Codec.

This means you can listen to 24 bit Hi-Fi / Hi-Res Sound with LG G5. At the moment the LG G5 is only only smartphone that comes enabled with the revolutionary Qualcomm® apt-X™ HD codec.The aptX™ HD Audio Codec delivers CD-like quality audio over Bluetooth that faithfully reproduces the full audio bandwidth and minimizes latency by significantly reducing the bit rate without affecting sound quality.

LG state that “now no wires are truly a thing of the past as you can bask in the sheer superiority of a 24 bit audiophile experience in total wireless comfort.”

Note that the APT-X HD codec comes as standard with the LG G5. You do not need the LG Hi-Fi Plus module.

The LG Tone Platinum Bluetooth headset is fairly slim made with an anodized brushed aluminum alloy trim. LG has used a Balanced Armature design as the sound module to minimise distortion and reproduce the sound accurately. The headset also offers noise cancelling dual microphones for clearer calls even in the noisiest environments. In testing these worked really well. Calls were exceptionally clear. LG added Voice Command to handle incoming calls.



Tone & Talk app has been enhanced to support Voice Memo and Find Me via any Android smartphone (version 4.1 and higher). The LG Tone app adds a lot of extra functionality and makes this headset easier to use.


The other controls on the headset are everything you expect and more. Controls for music, calls, volume, cable retraction and more as shown in the photos.

The Sound Quality

This is the part that matters most. Does the new APT-X HD codec work? In my testing it really does work and really well. It also sounds better than Samsung’s proprietary UHQ codec found on the new Samsung Galaxy S7.

As this is created by Qualcomm more headphones are due later on this year featuring this new codec which will undoubtedly become the new audio wireless standard.

LG’s decision to use balanced armature over a dynamic driver is a statement in itself. Balanced armatures tend to reproduce sound fairly naturally with delicate mids and treble.

I have listened to loads of different genres and all were faithfully reproduced. It is hard to believe these are wireless headphones. The Tone Platinum are not bass heavy. But if the track has bass it digs deep too. Classical and vocals were wonderful. Playing flac songs and again the sound quality was excellent.

My current favourite Bluetooth headphones are Plantronics BackBeat Pro. These deliver huge amounts of bass and impact. A lot of people will listen to these are even prefer them on a quick listen. These are over ears and massive so have the ability to deliver such impact. However, over a longer listening period the LG Tone Platinum will triumph. Ear fatigue is non existent and the overall quality is way above the Plantronics.

Another bonus is that the in ear canals are comfortable even after lengthy usage.


Qualcomm’s APT-X HD is the real deal. The LG Tone Platinum are fantastic as a headset from a feature count, superb for phone calls and more and sound brilliant with your music.
