To start with, I made that comparison video. So if you have any questions, feel free to ask!
I am utterly disappointed by the speaker quality of the Desire HD.
I fear that this is hardware related, as the speakers sound very high-pitched, without any low tones at all. Also, when at maximum volume playing high toned music, the sound starts to distort and crackle. As you can hear, you can hear the low tones pretty loud and clear on the N95, but on the Desire HD, you can't hear it at all. The volume is noticeably about 2.5x louder on the N95.
If you compare the Desire HD with the Galaxy S, you will quickly notice that the Galaxy S has even better speakers than the N95, with plenty of low tones, at a high volume. The volume of the Galaxy S is many times higher and clearer than the Desire HD.
All of this leads me to conclude that for a flagship phone as the Desire HD is, it really has crappy speakers, and I truly don't understand how they could make a ****up like this. How much would good speakers cost anyway? Cents?
I expect a flagship multimedia phone like the Desire HD is to have proper speakers, comparable or better than we had in the N95 time (the flagship multimedia phone 3+ years ago). Samsung seems not to have any trouble to achieve this, but for some reason HTC didn't -utterly unexpected-.
Now let me be clear: even with the bad speakers, the Desire HD is a much better choice than the Galaxy S for several reasons, but really, HOW THE HELL have they achieved to fail so miserably on this point?? I'll make another video soon to compare speakers of the Desire HD against the Galaxy S. Also check out the other video's in my channel, rate and comment!
