Customer Reviews
3M™ WorkTunes™ Connect Wireless Hearing Protector is rated 3.4 out of 5 by 382.
Rated 2 out of 5 by from great with fatal flaws i've owned two of these now. first was great until the low-quality micro-usb charging port broke. the second wasn't as good (they increased the long-press duration on the single button to what feels like half a minute) and then the fragile little wire connecting the two muffs broke. i suppose it's still under warranty but it's frustrating. it's a shame, too -- before all this i recommended these to probably a dozen people. if they put the wire in a simple hinged housing like on any pair of cheap headphones and upgraded the charging port to usb-c, these would be the best headphones for the money anywhere.

Rated 3 out of 5 by from USB Charging port fails after a while It is a very good product until charging port pulls into the plastic housing and it becomes impossible to charge it again. Unfortunately, it is very hard to unscrew the components and fix the issue. It is common problem and most users report the same issue in the reviews. I hope 3M fixes this design problem. Otherwise, it is a good headphone with good noise reduction.

Rated 1 out of 5 by from USB charging port failed I had these headphones for around 2 years under very moderate use. Was very disappointed to find that the charging port pushed into the plastic housing making them unable to charge. Seems other people have had this same issue. Now I just have some really expensive earmuffs. Very disappointed and a waste of money. I tried getting a replacement but unfortunately i was told they were out of warranty.

Rated 1 out of 5 by from They worked well… for a while I used them on and off for a month and a half and they were great! One day I connected to them and one ear doesn’t work.

Rated 3 out of 5 by from Good Protection and Sound, Bad USB charger port My first pair were given as a gift. Lasted almost a year with intermittent use before USB charger port pushed back into headset as described in numerous other reviews. Mine was out of warranty so I took it apart to see what the problem was. Micro USB port is soldered directly to circuit board via 4 small mounting pins and only has electrical contact to board through physical contact with USB leads. Very poor design for an electronic device that will be used in a work environment. It needs to have a redesign to more securely mount the USB female adapter to the headset. Also battery is mounted on circuit board and unable to access it if it needs to be replaced over time. This could also be a redesign feature. Overall a good product other than these 2 design faults. I have bought another worktunes headset as a replacement, but this time I also purchased an micro USB extension (6 Inch Cellphone/Tablet USB Micro Male to Female Sync & Charging Extension Cable) on eBay and zip tied to new headset.

Rated 3 out of 5 by from Faulty Micro USB The headphones worked great until the micro usb inadvertently got pushed into the molded plastic. I can no longer charge the headphones because the micro usb cannot reach in to connect.

Rated 5 out of 5 by from Great for listening to music whilst working Had these for almost a year and they haven't missed a beat (pardon the pun). Easy to pair to my Samsung S7 and S10. Quick to connect each use, battery good for all day and sound is always clear with good base. Oh, and they are also hearing protectors. Would recommend.

Rated 2 out of 5 by from battery is always low I've had them less than a year and really liked them. Now, the battery with what I expect is a full charge, lasts just two or three hours
