We put the Samsung I9300 Galaxy S III and the HTC One X side by side in our loudspeaker performance test. The Galaxy S III comes on top with a better all-round mark (Good) while the One X got an Average rating.
In voice output the Galaxy S III is way ahead and it's slightly louder when reproducing pink noise, too. Keep in mind that if you're using ringtones, which resemble an old-fashioned phone ringer, the One X and Galaxy S III are almost on par.
|Speakerphone test||Voice, dB||Ringing ||Overal score|
|HTC One X||65.1||66.0||75.8|
|Samsung I9300 Galaxy S III||75.1||66.5||75.0|

The Samsung I9300 Galaxy s III turned out to be one of the most talented musicians around and managed to edge out the One X in the audio quality test.
The two have almost identical volume levels when connected to active external amplifiers, but the Galaxy S III has much cleaner output with no weak points whatsoever. The One X on the other hand has higher than average distortion levels, which is rare to be seen in a high-end smartphone.
Things were a bit closer when we plugged in a pair of headphones. The Galaxy S III still got the better results on most parts of the test, but at least the One X managed to score a point with its lower stereo crosstalk. It's not enough to prevent this round from going in favor of the Samsung flagship though.
