Sonic Impact iP22

The iP22 was an audio peripheral manufactured by Sonic Impact Technologies for iPods with 30-pin dock connectors.

History
The iP22 portable speaker and storage case was introduced in 2006 and was similar to Sonic Impact's i-Pax, but included a 30-pin dock connector to support larger iPod models. It was also cheaper than the i-F1 by relying on four instead of a rechargeable  battery for portable operation. It could charge an iPod with included AC adapter and its 3.5 mm jack allows for use of headphones. The speaker can be closed within a durable hard case for transport.
