Product Overview

Sync Stereo Earmuffs with Audio Input Jack. Most stereo earmuffs provide some level of hearing protection. But often sacrifice sound quality for attenuation. Sync is a stereo earmuff that's in sync with proper levels of hearing protection, high-fidelity sound, and your ability to listen to portable audio devices safely at work and at home. Sync's acoustically optimized ear cup design delivers excellent protection against hazardous noise. Inside, Sync's speaker technology manages sound levels reaching the user's ear to a safe 82 dBA. That's well within OSHA's recommended 85 dBA Action Level. At any workplace, Sync helps keep you motivated, and productive. Sync has no volume knob or power switch to fiddle with, and no batteries to replace, so users can just plug in and go! The system controls volume to safe levels. But users have everything else just the way they want it. They simply plug Sync into their MP3 players or other portable audio devices. They turn on and off power and adjust volume through their portable audio devices, too. Sync's DJ-inspired earcup design and sound quality are on par with other professional and high-end personal headphones on the market. Sync boasts the most stylish design of any industrial earmuffs you've seen with hearing protection that beats any entertainment headphones on the market.

Customer Questions & Answers

Is it Bluetooth

Asked by: Brandon
No. They are wired.
Answered by: rh
Date published: 2017-06-20

what type of batteries does it take, how many and is there a rechargeable battery for it?

Asked by: mm
These have no batteries and run from device power like a standard earbud- a big plus IMO
Answered by: Myke

Can you talk on your phone with them

Asked by: Truck
Nope. The seals make them too tight. A wired earpiece might work, but its microphone would be exposed to your noisy environment.

How comfortable are these if you wear eyeglasses?

Asked by: JerrySee
They press on the earpieces of the glasses if they are not extremely flat. That said, you don't get earpiece pain for an hour or so. The seal for sound exclusion is very slightly impaired by the glasses earpieces passing under.

Customer Reviews

Sync Stereo Earmuffs with Audio Input Jack is rated 4.4 out of 5 by 96.
Rated 5 out of 5 by from Nice They work very good. . . .
Date published: 2015-04-01
Rated 4 out of 5 by from Good build quality, feels sturdy, sound is okay The jack, headband are nice and strong. The cushions are easily replaceable. The price is less than low-end headphones you could get elsewhere, while giving you added functionality of hearing protection! All of this is positive. Only left to be desired is in the sound quality. The medium range is good, upper and lower register struggle. So, it's actually pretty good for speech, but if you listen to music any bass drum or high hat will sound a little unnatural.

Rated 2 out of 5 by from Too Small I've used all sort of hearing protection devices over the years, but this is the first one that absolutely would not fit-not even close. Would not go down all the way over my ears, and was VERY tight. The tightness may have eased with use, but to have a hearing protection device not completely cover the ears is just wrong. If you have a small head, they may work for you, otherwise, I'd advise not wasting your time on this one. On the audio side, the headphones were very low quality. I've had much better sound from $5 discount store headphones than these could deliver. Wasn't expecting anything too wonderful, but was expecting better than this. Overall, a very disappointing product. I returned it and am going to try something else. Too bad someone can't produce a simple mp3 capable hearing protector at a good price. Doesn't seem that much too ask, but right now there is nothing in the market that meets basic requirements without spending at least $50.

Rated 5 out of 5 by from Excellent quality My local home Depot didn't carry these, so I had them shipped to the store. That was all a good experience. The headphones were surprisingly high quality for the price. Everything about them is well made. So I was excited to check out the sound. When I put them on, the first thing I noticed was how tight they were, but they blocked out a lot of sound, similar to wearing ear plugs, so the tighness should be expected for ear protection, I guess. Then I plugged in my Droid phone and played a few different songs. I was very impressed with the sound! I was expecting weak bass from some of the reviews that I had read, but the bass was solid and so were the highs and mids. I am looking forward to the next time I mow the lawn to try these out! I would definitely recommend these headphones. The only shortcoming is the very short and cheap headphone cord, but those are inexpensive to purchase separately.

Rated 3 out of 5 by from Decent With the only 2 times I've used them so far, they muffle out bad loud noise decently. When I had my small gas powered snowblower going I couldn't really hear the music through them, but I'm also not a fan of blasting music in my ears. They are small, but for me they are comfortable.

Rated 5 out of 5 by from Perfect for what I needed Perfect for use on tractor w bush hog. Also use mowing and brush cleaning with trimmer and saw. Weight seems lighter than radio ones, plus batteries. Volume controlled by iPod and sound quality is good. Price cannot be beat!

Rated 4 out of 5 by from Good buy Purchased for mowing with comercial ZTR. Blocks the mower noise well and I can listen to music on my cell phone as well as hear the ring on incoming calls. It is a little small for my fat head but still covers the ears.
Date published: 2014-12-09
Rated 5 out of 5 by from Headphones are quality for the $ ! They are very good at suppressing noise. Worked great at the gun range and listening to music is a plus! I attached a bluetooth transmitter/receiver to the headset for wireless connection to my smartphone or mp3 player.
Date published: 2014-12-17
Rated 2 out of 5 by from Lousy audio!!! Headphones are comfortable, muffles sounds well, but the quality of the sound is poor. It seems as though the audio frequency response is off as there is a noticeable lag in the music at certain frequencies. Makes using them for listening to audio while wearing them in a noisy environment not very enjoyable. This why I bought them, so I am overall not pleased with this product.

Rated 5 out of 5 by from Great value For the money, you wont do better. I used to put earbuds on under regular earmuffs which was pretty uncomfortable. These are comfy, have good sound and at the price, unbeatable.
Date published: 2014-09-13
Rated 5 out of 5 by from Well worth the price If you have low expectations for what you can get for such a low price, this will astound you. The ear pads are made to be sweated in, as they are of rubber like texture. Great for lawn mowing. Also, the brand is known for ear safety and this should primarily be used as such. Worth a shot for home owners.

Rated 4 out of 5 by from They Are Exactly As Described I needed a new set of over-the-ear headphones for a small recording setup. For $8, they work fine. No, they are no where nearly as good as my old Sennheiser's, but they do the job well. For the same price, they also had the ones with the built-in AM/FM radio. If it wasn't for the ugly antenna sticking up, I might have tried those.

Rated 5 out of 5 by from Music to my ears! I bought these headphones so I could teach my 19 year old son how to mow a lawn. I made a deal with him that if he could mow it without any mowhawks, I would let him plug in his mp3 player. It worked! And these have really nice sound for what they are.
Date published: 2014-07-30
Rated 4 out of 5 by from Good choice. For the price, I think this set of phones is the best product of it's type out there. However, I would caution that Howard Leight does not design it's earmuffs to fit larger heads. I can barely wear it over a ball cap.

Rated 2 out of 5 by from does not reduce noise very much does not reduce noise very much at all. bulky. a LOT of pressure on side of head yet doesn't seal well around ears (cups sit crookedly). very uncomfortable. invest in better ones from shooting range or hunting supply.

Rated 5 out of 5 by from Much better than expected This was one of those deals that leave you thinking that you are surprised how good it turned out to be. I did not expect such quality at such a low price. I am very satisfied with my purchase.

Rated 4 out of 5 by from Nice Ear Muffs The ear muffs fits nicely over the ear. The sound when plugged into an Ipod was average, not the best but a good added feature if you ever want to listen to music while working power equipment or at the range. Works well when shooting at the range. Great price.

Rated 5 out of 5 by from Absolutely Great - Makes Cutting The Lawn A Joy Noise protection is great and the music quality awesome. Will never be without these again.
Date published: 2014-08-12
Rated 5 out of 5 by from I didn't know I wanted these! I wanted shooter's grade earmuffs that I could wear over my MP3 earbuds when I cut grass. Now I just plug my MP3 directly into the earmuffs for better sound and exceptional outside noise reduction.

Rated 5 out of 5 by from Great but... They work really well, but are to large if using at a gun range to shoot rifles.
Date published: 2014-08-05
Rated 4 out of 5 by from Very nice product for the price! Pretty good sound quality and fairly comfortable. Does a good job of quieting motor noise while delivering good sound from your music source. I just used them plowing and was very happy doing so!
Date published: 2014-01-22
Rated 4 out of 5 by from Solid Ear Protection They provide good ear protection. The speakers are not very loud but you can hear the music. How load do you need it to be? Has a tight fit. It will keep your baseball cap from flying off on a windy day. Good overall product.
Date published: 2013-06-25
Rated 5 out of 5 by from I love this product I use this product while I use my riding lawn mower. I am able to listen to music comfortably, and since I use my phone to do so, I hear any incoming alerts or calls.
Date published: 2014-02-18
Rated 3 out of 5 by from I just needed a low cost pair of noise canceling headphones. These work fine. Not expensive and as good as headphones at twice the price. They do need a little adjusting to make them comfortable.

Rated 5 out of 5 by from Great for very large heads Very good sound attenuation. Good sound quality and the cable is nice and short so it's harder to snag when working.
