Product worked well with small modification under moto helmet. Sound quality is good with good bass. Delivery prompt and fuss free.

They do a good similar job as to earplugs toning down the harsh noises from work. Volume could do with being a little bit louder but maybe that's intententional? Music sound quality I give a 3 out of 5. Around average

So far they have been great. Working in a noisy workplace they have been awesome to listen to music without having it too loud to compete with grinders etc. Yet to use them with my motorcycle helmet. But so far looks very promising. No signs of wear so looks like they will last well.

Comfort and cost once I mastered the foam inserts.

I perchaced these for motorcycle riding to drown out the noise from the wind and listen to music.

I'm quite surprised by the audio quality and happy it keeps the outside noise out as well as stays in my ears unlike other styles of headphones
