Research in Motion is definitely making sure that the BlackBerry 8300 will appeal to the average consumer. Unlike most MP3 playing mobile phones and all BlackBerrys before it, the BlackBerry 8300 headphone jack accepts standard 3.5MM size headphones.

“Why is this important?”, you might ask. Well, even though there are 2.5MM to 3.5MM convertors, the sound quality when using a converter with premium headphones is often times staticy, usually because the mobile device doesn’t provide enough power through the converter to the headphones.

This feature will go a long way to get MP3 junkies to put down their iPods for MP3 playing mobile phones.
