Okay, okay. I’ve seen a lot of audio player enabeld phones review. But, most of them only evaluate the phone functionality, audio player interface, and etc… etc. I know that sound quality tends to be subjective (tested with ears), but it’s not a bad thing if we test the objective quality (tested with equipment), right?Few weeks ago, I borrowed two phones. One was the Nokia N91 and the other is Sony Ericsson W810i. Two are audio player enabled phone. So, let’s evaluate them.

For introduction, I don’t use sophisticated equipment like Audio Precision. It’s just a software named RMAA and a sound card as D/A. I have few cards like EMU 1820M and ESI Juli@. Both are professional cards. But for this test, I just use prosumer card the M-Audio Revolution 7.1. This card has flat enough response (+0.13, -0.07 dB, and >90 dB of noise, dynamic range, and stereo crosstalk @ 16bit/44.1 kHz). If possible, I will re-test with my EMU or Juli@, but I believe the result will not be different. The RMAA is well know an excellent software for this purpose. One time, the creator had done comparison with Audio Precision and the result was quite similiar. So, we simply can trust this software

If you have been in this world for at least 15 years, I’m sure you know what is “Walkman” refers to. At that time, maybe you didn’t know who is Nokia.

Yes, every handset maker has decided to include this feature into their handset. But we will discuss only two brand. First, the Sony (Ericsson) with its Walkman phone. Second, the Nokia due to their position as largest handset manufacturer.
