With the HEOS Go Pack you turn the HEOS 1 into a mobile Bluetooth speaker. This accessory package for the HEOS 1 consists of a battery, Bluetooth adapter and waterproof attachment. You attach the speaker to the battery with 1 turn, after which you use it wirelessly for 6 hours. Step outside your Wi-Fi network, because the adapter establishes a Bluetooth connection between the speaker and a mobile device. This way you can easily take it to the garden or the beach. Click the waterproof attachment on the speaker so that the inputs are not affected by dust and splash water. With this package, the HEOS 1 is ready for your active lifestyle.
