Headphone Parameter Bying Reference

I made this reference list from watching couple youtube videos.

  • Frequency
    20Hz – 20kHz low end
    16 Hz- 24kHz good
    5Hz – 33kHz not worth money
  • Impedance (how much power you need to move speaker inside headphone)
    < 25Ω low end
    25Ω – 200Ω good for mp3 players, phones, tablets, laptops
    >200Ω not worth money
  • Sensitivity (how well sound is recreated using limited amount of power from source)
    > 110 good

NOKIA E51 supports larger than 4GB microSD cards

After installing FLAC player on my NOKIA E51, i needed to expand memory. In official nokia documentation it sais, that max memory size is 4GB. But in all other web pages I’ve checked it sais up to 16GB memory cards.

So today I bought 8GB microSD memory card. That means phone should support also 16GB cards.

Now I’ll copy my FLAC music files to the phone. Wohoo!

How to play FLAC files on NOKIA E51

I was thinking to buy flash player which supports FLAC format. I found some, but despite their advertised “superb sound quality”, the price is unacceptable. So after nth try I found a solution how to play flac files on my nokia E51 (Symbian S60 FP1).

Download Symbian OGGPlay port to Series 60 V3. You will get zip file. Save it on desktop, extract. There you will find ReadmeFirst.txt file, where detailed instructions are written. Read it.

Download link for OGGPlay 

Then I used Nokia PC suite. I connected phone and started Nokia Application Installer from Nokia PC suite. This program will be used to install OGGPlay.

On the left, find where just downloaded and extracted OGGPlay files are located. We need two files to complete installation. The screen should look like below.

Nokia Application Installer

First move OggPlayFonts.sis to the phone. The phone will ask, if I want to install. Just confirm few prompts on the phone to finish installation. Then restart the phone (instruction from ReadmeFirst.txt).

After restart move another file OggPlayS60V3_1_72.sis to the phone. The phone will ask, if I want to install. Just confirm few prompts on the phone to finish installation. No restart is needed.

The application will be installed in installations folder in Nokia e51 as OGGPLAY. Almost done. Just copy files to the phone and enjoy FLAC quality.
