Apple - Vintage accessories - Apple Pro Speaker (Model M6531) - With 3.5MM Jack mod The Apple Pro Speakers were an icon of vintage Apple design. And they sounded great, especially considering their size and the fact that they're passive. These speakers were sold in the G4 iMac era, for example with the Tournesol iMac models. They originally came with a 2.5MM Jack plug. These speakers have been modded with a 3.5MM Jack plug so they can be used with your phone or any other source. Imagine being out with friends, and instead of using a Bluetooth speaker for your phone you whip out these vintage beauties! The speakers are in good condition, with some traces of usage. They have been tested and are working perfectly. This model is not in production anymore. The lot will be carefully packed and shipped with tracking nr.
