I now have LG Tone Pro HBS-750 Bluetooth Headphones.

And unlike how it went with the previous set, I paid the full price for these, and know that they are genuine.

I can now comment accurately for the first time, about the “aptX” sound compression they use.

I understand that most of the music that I will be playing, has already been MP3 or OGG compressed. But with my simple headphones, that were wired to the stereo mini-jack on my phone, there was a loss in quality, just in getting the sound to my ears, after MP3 or OGG decoding. With aptX, it could be argued that there is also some small loss of quality in getting the sound to my ears.

aptX, and the HBS-750 headphones, are able to get the sound to my ears, after lossy decompression, better than the wired headphones could. So the only sound artifacts that I will ever hear with these, will be those due to MP3 or OGG, and the OGG files will play better again than the MP3 files did, as the OGG files are supposed to do.

The sound of these headphones is truly superb.

Further, the reason for which the suggested app ‘Tone And Talk’ was not recognizing the supposed HBS-730 headphones, was the mere fact that this app was able to read the meta-data of those, and was able to determine, that those were just not on the list of supported headphones, even though I was fooled into believing that they were.

Tone And Talk works properly, with the HBS-750 headphones, that are genuine LG headphones. That is, unless I am to do a detailed test of this app, which may come later. But the app does not just sit there and stay lame, as it did with the counterfeit headphones.



The so-called HBS-730 Headphones were Counterfeit.

I had written some postings, which are by now deleted, according to which I had bought LG Tone+ HBS-730 Headphones, and where I was trying to analyze the sound quality.

I had previously understood that there exist numerous sound compression schemes such as MP3, OGG, and aptX, which have a great deal of complexity. But what none of my foreknowledge told me, was to what extent the quality of each of these schemes is supposed to make their existence transparent. The goal in designing them is actually to make their existence unnoticeable, if possible.

According to what I have now found out, the fake headphones that I had bought, did not only have sound compression, but a level of sound quality that can be regarded as defective. Even though aptX is complex, we can expect much more of it than those headphones were producing.

(Edit 06/25/2016 : ) Those headphones dropped the quality of my sound to be approximately as if it was 128kbps MP3 sound across-the-board, while MP3 and OGG Files that I mastered myself, are at 192kbps if not 256kbps.


Those headphones are history to me. One of the death-knells, which finally allowed me to understand that those were fake, was the unanimous consensus that the HBS-730s are supposed to be able to play close to 10 hours of music, but that mine could only play music for 135 minutes.

There is some amount of discrepancy which can be accounted for, just because the batteries may be on their first charge. But that amount of discrepancy should be less than 5:1.

There were actually numerous hints given off by those headphones, which all seemed to point at the same conclusion. I am ashamed at myself, for not having spotted said forgery faster.
