I got these because I wanted to listen to podcasts while I mow my yard and do yard work or work in my woodworking shop. First of all, these are great at blocking out noise. Just using them for hearing protection is worth the price. But they also have bluetooth and it was extremely simple to connect them to my phone and they always connect quickly whenever I use them. They also sound good and I find I stay out longer doing yard work and looking for other things to do outside because of how good they are and I want to finish the podcast or radio show I'm listening to. The battery also lasts a long time. I've had them for several months now and I'm still waiting for them to tell me the battery is low on charge. When I hit the power button to turn it on, it tells power on, the battery status, they're pairing, and then connected when they connect. All of that happens quickly and I like the verbal information it gives. They are also fit well and are very comfortable. I've worn them for several hours at a time and they never became uncomfortable and they've held up well to sweat. I wipe them down with a damp paper towel when I'm done and they don't even look like they've been used. I highly recommend them.

Way better than expected. Sound quality is very good at this price point, not too much bass, volume is high enough without it being too loud. Comfortable enough to wear for a full 8 hour shift. Battery life is great. 1 charge have me a full week with the battery level still reporting at high. Overall way better than the in-ear buds I've been wearing for the last 10+years.

Great value BT muffs! Have used the 3M Worktunes for years, until the USB port broke. Bought these to replace and love them. Great noise suppression to begin with, but markedly better audio as well. Can wear easily on the mower, skidsteer, or excavator. The button volume controls are a nice addition. So happy with them after just one day, I bought 2 more pair for the family to use. BT range is very good, I can leave them in the cab and walk 30-40’ without loosing connection. Quickly pairs again when I walk back into range. The mic works as well as expected and my wife reported that she can hear me with an engine idling in the background (not at full throttle, but wouldn’t expect that). Haven’t had them long enough to say how long the really battery lasts, but haven’t had any issues with them over a few 3-4hr work sessions so far. They shut off after loosing BT connection, so the battery won’t be drained by leaving them on. USB C charging connection, which is great. They do have an audio cable port that can be used for corded connection if needed. Good fit with plenty of adjustment. The foam and gel pad versions are both very comfortable. I bought the gel version for myself (since I wear them much more than the rest of the family), and they are better, but not by a massive amount. The padding on the arch the spans over your head on all versions is a welcome addition to this user, I was getting very tired of the hard plastic on the 3M version resting/rubbing on my bald head! The only improvement would be an optional boom mic, but that’s not a critical need for my use.

I'm so impressed with these little bluetooth ear defenders! I'd never heard of the brand so I thought they might be a bit naff but I've been using them every day and they've been great. Pros: The battery life is amazing. Nice soft headband. The controls for changing volume are nice. They connect easily and I've never had any issues with pairing or connection unlike some bluetooth earphones in the past. Sound quality is better than I expected (are they as good as a decent pair of over ear headphones? No, but they still sound good for what they are). Cons: There isn't a lot of room for your ears inside and the speakers will be pressing against your ears. There is padding over the speakers but I still find them painful to wear for longer than about 2 hours in one go. I think more generous ear pads would have been nice since it would have given more clearance for the ears. Over all I really rate them. Good quality, great battery life, reasonable price. Only downside is comfort when worn for long periods.

My husband loves them! Easy connection, excellent sound quality, comfortable, blocks outside noise (he uses them while mowing the lawn), and when you turn them on, they say how much battery power is left. Very, very happy!
