Issues. Would not buy it again.
Ok well I have had this item for about a year now. First I would like to say it does not have audiophile like sound for me. Not really happy with it. Issues I am having lately are it does not want to pair new devices will not go into what I call search mode to find them no matter how long I hold the Bluetooth button down. It has been shutting off on me for no reason no matter the volume or battery level. And the one little thing it needs is am/FM capabilities. That is just a small thing that is so big.

Strong sound
2 years On the job, by the pool, in the garage this thing sounds great at any volume. Until recently, it has started clicking/ popping at med to louder volume. Sometimes it will work properly and when it does it’s great

Terrific sound quality.
I've owned this speaker for 3 years. It has amazing sound quality. I do wish it had FM tuner. But simply as a bt speaker, fantastic. Durable and lasts at least 8 hours on xc5.0 m18. Do also wish it would double as a charger when plugged in.

Great speaker
Speaker pairs easily and stays connected well. Sound quality is pretty good, lacks bass though. Vocals are clear and it does play very loud. Great that it can sit on my toolbox running on AC then be unplugged and run on a 12/18 volt battery and go anywhere.

Bluetooth issues
Bought the speaker and was immediately impressed. Sound was spectacular and a very tough speaker.. good for the job site! Till the Bluetooth stopped working. Now the Bluetooth won’t even cut on.. but the AUX works fine.. just nice to have a Bluetooth speaker that actually can Bluetooth..

Impressed so far
Bought this speaker less than a week ago. Mainly for camping, fishing and general outdoor use. Used it this past weekend while working on my snowblower. It was -8C and it held up in the cold with a light wind and the sound quality is great. The battery on my phone went out before the M12 battery on the speaker. I'm impressed with the build of the speaker look forward to many uses in the coming outdoor season.

Good speaker but ac adapter has never worked
Love every thing about this speaker. Good sound great Bluetooth range and a convenient size for the jobsite. But the ac adapter has never worked. So I’m only allowed to run it on m18 batteries which is a problem when I need that battery for one of my tools.

Needs improvement
My wife bought one and at first I loved it....did everything I it's useless... when I try to power it up the power light flashes 1 time and that's all....thought maybe the power cord so I tried using 3 different batteries that I know are good because I use them daily on other tools. Love Milwaukee but the speaker doesn't live up to the Milwaukee standard in my opinion

I need this power cord??
eduardo z on Nov 7, 2017
BEST ANSWER: What do u need?
Does it have am/fm radio?
Trey C on May 15, 2018
BEST ANSWER: No. Strictly a Bluetooth speaker. If you wanted to listen to the radio (live sports, etc.) you would need to stream it via your Bluetooth-enabled source device (like a smartphone) or connect a Bluetooth transmitter to a radio and pair it with the Milwaukee speaker. The alternative Milwaukee model # 2792-20 M18 Jobsite Radio & Charger has an built-n Bluetooth receiver.
Does it pair with 2792-20 ?
Wendell D on May 14, 2018
BEST ANSWER: No, both the radio and speaker only receive the bluetooth/wireless signal. You could only use 1 application at a time.
Where to find power cord?
