THE PRACTICAL PERSPECTIVE

Overall review.

Account for the size in your bag

At roughly 650 g, the speaker is worth packing when other people will listen with you. Think about how far you will carry it and where the strap will sit.

Compare bass mode at the volume you use

A dedicated bass control gives you two listening setups to try. Compare speech and a familiar music track at a reasonable volume to see which works for the room.
