Review: Excellent, would definitely recommend and buy for anyone avoiding noise from office, planes, or work. - I bought this as I'm sensitive to noise at work and for long plane rides. It is meant to be a substitute for ear plugs. It works very, very well. The muffs are surprisingly big in size, you will look a bit weird wearing it I suppose, but I'm fine with it. For its size, it is actually pretty light, and feels really light when you're wearing it. The head band is adjustable for most people's head size, mine is pretty big (I had to buy XL bike helmets) but it still fits well with some room to spare. Will work under a helmet as well, maybe not as comfortable but it's still fine, since the head band lies flat across your head, same as the metal cables connecting the muff to the band. The sound proofing is very good, but you can still make out what others are saying, which is a plus. It's comparable to wearing a set of good ear plugs, but way more comfortable for long periods. It's circumaural, so it covers your ears entirely. The muffs press lightly but firmly on your head, creating a seal, but it's not that uncomfortable in terms of the heat and humidity, as good as it could be I guess. I would have paid 3 times more for this product. Review: 100% spot on!! - Spot on. Comfortable, size is perfect, cuts out noise just as the spec sheet specifies. Absolutely valuable for money. Designed so well. This is the same one u see being used by the airports as well, so ur ears are protected. ## Features - Comfortable, high performance hearing protection - Designed for use in extremely noisy environments (95dB(A) – 110dB(A)); SNR 35dB - Significantly reduce both low and high frequency noise - A good choice for industrial areas, construction sites, airports and other high risk workplaces - One pair of black ear defenders with red trim, on an adjustable headband ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000VDX18E | | Age Range Description | Adult | | Best Sellers Rank | 2,183 in DIY & Tools ( See Top 100 in DIY & Tools ) 10 in Safety Earmuffs | | Brand Name | 3M | | Closure Type | Button | | Colour | Black | | Customer Reviews | 4.6 out of 5 stars 22,536 Reviews | | Fit Type | Over the Head | | Fit to Size Sentiment | Good | | Garment Size Country | Mexico | | Global Trade Identification Number | 04011333310274, 04046719386918, 07318640033405 | | Included Components | Ear Muff | | Item Dimensions | 20 x 20 x 20 centimetres | | Item Type Name | Earmuffs | | Item Weight | 14.11 Ounces | | Manufacturer | 3M | | Manufacturer Part Number | 310.10 | | Manufacturer Warranty Description | 1 Year Manufacturer | | Material Type | Plastic | | Model Number | 7000039622 | | Noise Control | Sound Isolation | | Noise Reduction Rating (NRR) | 35 Decibels | | Number of Items | 1 | | Number of Packs | 1 | | Pattern | Solid | | Product Style | Optime III Headband | | Single Number Rating (SNR) | 35 Decibels | | Size | One Size | | Sleeve Length Description | Sleeveless | | UPC | 789957420764 806808764478 798256170638 785983351508 | | Unit Count | 1 Defender | ## Images ![Peltor H540A-411-SV Optime III Ear Defenders Headband - Image 1](https://m.media-amazon.com/images/I/71Vqh2hzM0L.jpg) ## Available Options This product comes in different **Color, Fit Type** options. ## Questions & Answers **Q: will they cut out quarrelling neighbours - and noisy traffic?** A: Most of it definitely. Neighbours for sure and as for the traffic - depends on how noisy it is of course and how close to it you live. What even these babies can't block out completely is bass since we, the people, not only hear bass with our ears but feel it with our bodies and car engines can produce some fairly low frequencies. You should be fine from low mid to high frequencies so you won't know about the neighbours as long as they don't throw each other at the walls which would naturally produce some bass. ;) **Q: Why SNR 5 db? Should it not be SNR 35 db?** A: Yes it should be - Typo ... **Q: I go to a church with very loud levels of live music. Will the 3M Peltor Optime III be suitable for me?** A: Technically yes - I use mine for when I go shooting at a range using military rifles; noisy would be an understatement. No problem, also you can hear normal conversation when wearing them. From a fashion standpoint - big and bulky. Horses for courses. **Q: I work in live music - how much will these cut out? Ideally I want to hear very little** A: I work in construction these will reduce the noise level but will not cancel everything out they are rated up to 110 db the next highest rating is for aircraft the optime 4 always look at the db rating ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent, would definitely recommend and buy for anyone avoiding noise from office, planes, or work. *by M***N on 28 July 2016* I bought this as I'm sensitive to noise at work and for long plane rides.

Absolutely valuable for money. Designed so well. This is the same one u see being used by the airports as well, so ur ears are protected. ### ⭐⭐⭐⭐⭐ Durable with good noise protection *by J***7 on 10 June 2025* Durable and good performing ear defenders, been used for work 5-6 days a week over 1 year and still good. Dropped on the floor a few times(≤ 5) and no noticeable damage, only once it felt like noise attenuation in left ear wasn't working anymore but nudged it a few times and adjusted the cup over my ear, something clicked and it worked again. The deep ear cups help against heat and if you're so inclined ear buds fit inside, although comfort may vary. Probably should had bought a hygiene kit 3-6 months ago but that's still good value if you're using it for work and better care can be taken at home to avoid replacement. Still can hear people talking if that's a requirement but going forward they will be replaced by 3M Peltor X5A, at least for home use. ## Frequently Bought Together - '3 M Peltor 310.10 Peltor Optime III " - 3M PELTOR Ear Muff Hearing Protection, X1 Series, Noise Protection, Construction, Manufacturing, Maintenance, Automotive --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/47972998-peltor-h540a-411-sv-optime-iii-ear-defenders-headband](https://www.desertcart.sn/products/47972998-peltor-h540a-411-sv-optime-iii-ear-defenders-headband) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-10*
