Howard Leight Sync Wireless Earmuffs

Wireless earmuff (over-ear) headphones provide superior hearing protection and much better sound than either earbuds, earphones, or on-ear headphones. Their only disadvantage is that they're bulkier and weigh more than the other styles of wearable listening devices. Still, for maximum protection, and a great listening experience, they're hard to beat.


These Howard Leight Sync earmuffs have a lot going for them. At just over 14 ounces they're reasonably light, and the fully adjustable steel wire head band enables you to configure the ear muffs for a perfect fit, regardless of head size. The band has a textile lining on one side and PVC on the other, and is nicely padded for added comfort.

The fit is very snug, which is what you really want. If the earmuffs are loose fitting over the ears you'll get unwanted noise infiltration. I routinely wear them for a couple of hours at a time before having to give my ears a break. By then the area around my ears is feeling warm and there is a slight build-up of moisture on the earpads, especially if I'm doing a lot of strenuous work – a small price to pay for a high degree of hearing protection. I have an audiophile headphone that I can wear for a couple of hours at a time with much less discomfort, however, they don't offer nearly the same level of hearing protection. 


The Sync earmuffs feature Howard Leight's "Air Flow Control" that provides optimal overall protection for both low and high-frequency noise, along with "Volume Management Technology" that prevents sound streamed from audio devices from exceeding 82 decibels. This is a very practical feature, as exposure to sustained noise over 85 decibels can lead to hearing loss. 

The acoustically optimized ear cup provides a noise reduction rating (NRR) value of 25. I find they do a great job of turning the whine of planers and jointers to dull humming. When there is a lot of machinery noise in the shop I find that I have to turn the volume on the Sync and my smartphone to the highest setting in order to hear the music clearly.   

The earpads can be easily removed from the housing for cleaning, or to replace if they get damaged. They have a foam core and a vinyl or urethane cover. Just behind the earpad is a thin noise suppression insert.

Inside each earmuff is a 1-1/2" speaker that delivers crisp, clear sound and a decent bass tone.


On the bottom of the right earmuff housing is a 3.5mm AUX input jack (A) for connecting to other non-Bluetooth audio devices and a USB port (B) that you use with an included 41" cable and AC adapter for charging the internal lithium-ion battery.

I've been getting upwards of 18 hours of listening time with the volume set at about the mid-point. The battery takes about 5 hours to recharge – I plug it in at the end of each work day so that its always ready to use.

Wireless range is around 35 feet – as long as there is a fairly unobstructed line-of-sight between the earmuffs and mobile device. I typically carry my smartphone suspended in a protective case on my belt so the range isn't an issue.


The controls are also located on the right earmuff housing, which might prove somewhat inconvenient for left handed users. I found that once I memorized their location I could quickly manipulate the buttons while wearing the earmuffs. The power button (A) also serves for pairing the earmuffs with an audio device. The play button (B) serves to accept and end phone calls, while both song progression buttons (C) are also used to reject incoming calls and mute the microphone during calls. The Bluetooth symbol (D) illuminates green when pairing and streaming takes place, red when not paired, and blue for a phone call – somewhat superfluous when you're wearing the earmuffs. The volume control button (E) is easily accessible. 

The boom microphone is located on the opposite earmuff housing. I've only used it a couple of times, and found the call clarity reasonably good. The microphone has a fabric sock that helps deaden ambient noise.


The Sync is pretty well everything you'd want in a good combination wireless earmuff-headphone. You get the benefit of a decent noise reduction of 25dB, great sound from the 1-1/2" speakers, easy-to-adjust and reasonably comfortable earmuffs, upwards of 18 hours of listening time, and a microphone. They're ideal for the workshop or jobsite, but less convenient for a construction site.
