This is a Marshall Tufton portable Bluetooth speaker. It has tone controls for volume,bass and treble. It has a IPX 2 rating meaning it can withstand a little water. It has a 3 way speaker design with a rear facing driver. 20 minutes charge time will provide you with about 4 hours play time and a full charge can be done under 3 hours giving you 20 plus hours of play time. Bluetooth 5.0 The grill is a metal mesh design making this speaker very durable. It also has a carrying strap that can be removed if desired. You can check the battery level by a visual battery indicator on top of the speaker. I can assure you I’ve used this thing indoors and outside and it’s a beast of a speaker. It can get very loud but sounds great. In excellent condition. I do have the box for it also.
