Samsung Galaxy S6 vs LG G4 in-depth loudspeaker comparison
The Galaxy S6 and S6 edge have been out for a while and, sure enough, Samsung's Project Zero has apparently turned out to be a successful endeavor. The new flagships sure cross a lot of grief points that customers had with Sammy's top-shelf smartphones – starting with design upgrades, which finally boosted them in looks and feel, moving through camera improvements, and taking care of some of bloat around the interface, allowing for a more slimmed down version of TouchWiz.
As you can hear, there is quite some difference to the two speakers. The LG G4 delivers much more middle frequencies, making it sound a bit "flatter", but sometimes "fuller", without muddying up like the HTC One M8. The Galaxy S6 delivers a lot more punch in the high frequencies and has its mids scooped, so it is perceived as "clearer" sounding. Samsung's phone also sounds just a bit louder, due to the hump in the highs, but we are a bit disappointed to hear so much compression going on - when the snare drum hits, its attack causes all other sounds to "duck". The LG G4, on the other hand, does better at playing all instruments through its speaker.
We also ran a pink noise test through both phones. Pink noise is supposed to show a steady line on the spectrum analyzer, going at an even downwards diagonal from left to right. Now, seeing as our microphone, room, and other recording conditions would, naturally, introduce their own coloring to the results, we are not saying that the images below are fully representative of the speakers' actual qualities. They can, however, be used as reference to show how the phones sound when compared to one another. So, here are the slides:
The LG G4 may sound a bit "muffled" when compared to its opponent. However, listen to it on its own and you will be treated to a pretty even reproduction of all instruments in the mix. The compression is much less noticeable, and no frequencies pop out to repeatedly hammer our eardrums. Sure, its sound is just a bit "flat" and its volume barely surpasses the threshold for pleasurable media consumption, however, for this comparison, we'd have to say that the winner is LG's G4.
