No idea but I can definitely recommend them. I can still hear traffic etc, but it cuts the dull roar and wind noise. I used to get a roar in my ears up to an hour after. No longer.
https://www.ebay.co.uk/itm/Decibull...Highest-NRR-Comfortable-Hearing-/113053581548 I got some of these. You put them in hot water for 5 mins, insert in ear and allow to cool. They fit great. Two versions available. One especially for shooting etc. BUT when i came to put helmet on they got pulled slightly and wedged pulling helmet off again. They can be re -moulded, so maybe need to try again. Just a heads up to consider, if you’ve been looking at them. I’ll use them at work if i can’t get on with helmet use.
Have in mind that your two main sources of noise is wind turbulence around your helmet and the exhaust. Wind turbulence is usually 20-200Hz which is the lower end of the sound spectrum your ears can hear. Almost the same applies to the exhaust sound which is at a frequency of 100-200Hz (the highest dB at least). However, if you check the datasheet of the 3M earplugs, the noise reduction at this range is no more than 31dB. Car horns are usually around 350-500Hz for which the earplugs manage a reduction of 36.5-38.5dB which is not what you really want. I'm not saying they are bad, I'm just saying that they are exactly like every other quality foam earplug. 37dB is the mean for all frequencies which is never the number you are interested in. Any good quality foam earplug will do (the same job). I have also tried the more expensive earplugs that some people suggested (the ones with more advance filters in them) which are superior in transmitting the right sounds to your ear (I get better music quality from my intercom with those by far) however they are not better than the foam ones as far as noise reduction is concerned and unfortunately they don't stay as comfortable as the foam ones after two hours of riding. Otherwise they would be a nice alternative. But it's just my ears. YMMV
Absolutely right, and this needs to be emphasised, if we're talking about noise reduction as opposed to music, intercom etc. People sometimes seem to think that the more you pay, i.e. for custom-fitted, the better the noise reduction, but it's emphatically not the case. If you press manufacturers of custom-fitted on measured dB noise reduction they will admit that they can't match the best disposable foam, such as the Max-1 with its SNR of 37.
Another thing I should add is the fact of bone conduction. You will never get absolute noise reduction from wind noise since the vibrations of the wind turbulence will always be transmitted through your helmet to your skull. So your earplugs will be doing a great job in isolating the noise coming from your ears but your skull .... Maybe it's going to be the next big thing in noise reduction from the helmet itself. More exotic materials that dampen the vibrations and the like ...
I never hold the pink n yellow ones in for 40s. I guess I have the knack. I also use em for sleeping. I simply cannot ride without earplugs anymore. Annoying when the squidge deteriorates, but i always have a spare set under seat in toolpack or in my pocket.
Any good earplugs with BT speakers? I can’t use the normal speaker BT ones as it gives me a headache with the pressure the solid speaker has in the lid, so looking if any other options available.
I've found, though long-term experimentation with Autocom systems (and finally reading their fitting instructions), that speaker placement is absolutely key. Alignment of the centre of the speaker with your ear canal and also closest comfortable proximity to your ear has taken systems from being inaudible above 50mph to being able to hear sat nav, bike-to-bike and music at 90+mph. In Germany on the autobahn I did start to loose the ability to hear voice and instructions at 120+. This is with MAX1 ear plugs in, custom moulded in ear monitors might well be audible at higher speed but with their wires, tendency to 'leak' after time and relative expense I'm sticking with foam disposables. Concentrate on getting speaker position right and the difference will be significant. My Sena 10U is specifically designed to fit the Shoei GT Air. However, clipping the speakers into the relevant slots built into the helmet gave pretty poor results. Removing the speaker carrier frames (they just clip in) and using strong self adhesive Velcro on the back and in the bottom of the ear-well, along with dense foam spacers to bring the speakers closer to my ears, provided a custom fit that put them in the optimal position. This took a few attempts with different thickness of the spacers. Originally I used Autocom foam speaker covers but have since removed these and wear my Buff neck tube under my chin and over the top of my head so that my ears are just covered. This, I've found, is the most comfortable set-up. Obviously music on a bike isn't going to be of the greatest fidelity but on long motorway stretches at the legal limit and slightly above my Sena set-up is fine.
This is the main problem I've had with all the helmets I've owned so far. The pockets are never in the place I'd like them to be (my ears probably don't have the average position on a head) and when I put the speakers exactly at the center of the ear canal axis, they are afterwards covered by the cushions. Very frustrating. My solution to that was to buy wider/stronger speakers for my headset whenever those were available. This also helped with distortion as I don't have to keep the volume to the highest setting, or because the speakers themselves were of higher quality than the standard ones.
My X Lite has a decent sized pocket for speakers so I was able to play around with the placement of the speakers to get it optimum. I also got the optional 40mm speakers for better quality sound.
I went on an earplug oddessy when i owned a multistrada ...... Pink and yellow disposables, pretty good if i got them in just right Orange disposables, better but more uncomfortable Pinlock, not very effective Nonoise, not very effective Custom moulded , very disappointing ok at best Bose noise cancelling in-ear, very effective but difficult to keep in when puttin helmet on Isolate alluminium , almost a eureka moment ! Very good and easy to get in/out Isolate titanium, not materially better than aluminium So i’m using the isolates all the time now, they really are worth the £25/50 Steve
I junked a lid and went a larger size, thinking headaches were because it was too tight. It has speaker pockets and was build for them. Larger size was too big on for head and cheeks really. But fitted speakers and headaches.
The great thing about foam earplugs is that if you loose a pair or even one plug it's not a problem, I carry a zip-lock bag with spares in my tank-bag. Lost one last night, not a problem, just start a new pair. If this happens with moulded or other expensive plugs you're either looking for them or, if that's not successful, having to stump up for a new pair. I suppose if you've spent the money you maybe tend to look after them better...
I have one helmet with a bluetooth kit in it, a carbon Shark Speed R I can hear the tomtom directions ok with the isolates in, but as previous posters have said i had to locate the speaker very carefully. This took quite a few ‘experiments, as the speaker ‘cutout’ was not located next to my ear canal. A few goes at relocating the speaker, it’s just velcroed in’ and a happy compromise was found. Steve
I'm not about to disagree with you - if what you want to achieve is simply noise reduction then that can be achieved very cheaply. However, if you want to listen to music/satnav/comms while significantly reducing wind noise and without having to wind up the speaker volume up to potentially dangerous (to hearing) levels then custom moulded or in-ear plugs are, IMHO, the way to go. I can clearly hear whatever the sound source is at sensible levels and with significantly reduced wind noise.
just to chuck into the mix after many different types I settled on these https://www.ebay.co.uk/itm/Jack-Pyk...var=522301420181&_trksid=p2060353.m1438.l2649
