i have made research about the best phones in output sound speaker , include Quality\loudness , i've tried many phones like (3250-n91-n73-6270) thats from nokia , and (w550-w710-w800-w810-w850-w900) thats from SE .
i tried so hard to check MOTO E2 but i could not find one in my country ,
many people love the N91 and believe that its the best phone in sound features BUT actually i tried that phone and i can say that the output speaker sound is just like all the other N series Phones , in another word its just a normal sound and i'd like to give it 2 of 5 stars .
about the 3250 , in my opinion it has a very good output sound but it still need more loudness and quality so i'll give it 4 of 5 stars ,
well , i can order all nokia phones from the best to the worse :
3250 4 stars
n73 3 stars ( good output sound but poor in loudness and low bass )
6270 3 stars
n91 2 stars
SE Walkman brand phones : last week i've sold a w850 i loved it very much and i had no prob with the device but after i got the W900i today i noteced too much differ from the W850 about the loudness ONLY but these two phones r the best ever Walkman phones from the Output speaker sound and i can order them like this :
W800 3 stars ( loud enough but low quality and bass )
w810 3 stars ( not loud and not enought bass )
w550 3 stars (verrrrrry loud but worse quality , you can only hear the ssssssssssss sound )
w710 4 stars ( loud enough (not the loudest) , and good bass )
w850 5 stars ( good volume and great bass )
W900 5 stars ( the loudest phone and high bass )
Well in the end you can say W900 - W850 - 3250 is the best ever phones about the sound Quality\loudness .
Look you must know that i've made these experiece in quiet environment, i've used many songs ( same song for the single comperssion ) .
i didnot made my ratings because i love that phone and i hate the other one , i have a big mobile shop so you can say that i own all that phones and when i say that N91 got only 2 stars i didnot mean that N91 is bad phone , its just my opinion and i hope that you will understand me in this .
i'd like to see your opinion about this report and currect any thing wrong , thank you all .
