Product Features:
1. Standard 3.5mm Jack Audio Adapter:
Enable your GBA SP to use a standard headphone jack to get full stereo sound. (If you have headphones with a built-in microphone(or a 'headset'), the sound WILL sound distorted. You have to use regular stereo headphones with no mic.)
2. GBA SP Lacks a Headphone Jack:
You cannot use headphones and charge your GBA SP at the same time as they both use the same jack. So if you want to play with headphones exclusively, you'll need to keep your GBA SP charged.
3. Only Compatible with Nintendo GameBoy Advance SP:
The GBA SP lacks a headphone jack completely, so this peripheral is needed to use headphones.
