Compared to the N800, my new N810 have a pore sound quality using the integrated left speakers. I first have think that the N810 only have a right speaker playing the right channel only. But after several tests I cam to the conclusion that the N810 have also a left integrated speaker playing the left channel, but with a very poor sound, especially at low frequency. I used this page to get some sound test files: http://users.swing.be/hdepra/home/P22/E-sounds.html On my N810 the right sweep test http://users.skynet.be/fa046054/home/P22/track26.mp3 sound fine. The sound is loud and clear even in the first second of the track when low frequency are played. But the left sweep test http://users.skynet.be/fa046054/home/P22/track24.mp3 sound disappointing in the first 20 seconds. Almost nothing are audible in the first second of the track when low frequency are played. After about 20 seconds, the sound is more comfortable but I still get the feeling that it is not as loud as in the right test. Finally when playing the drum solo stereo test http://users.skynet.be/fa046054/home/P22/track39.mp3 I almost not here the left channel, only crappy noise when the drum sound should can from the left channel. So I wonder if my N810 have a fault in his speaker left channel, if this is a design problem, or if this can be a software problem (error in a DSP code ?). Can someone try to test his N810 using the above URLs and share his experience ? Only the integrated speaker is to test, the line out jack sound very good. Apart this sound issue (that can be only on mine), the N810 is a superb product. Thanks in advance, -- Jean-Christian de Rivaz
