Review: take the edge off of painfully loud gigs without spoiling your enjoyment. - These came recommended; I have tinnitus and some hearing damage so as a live music lover need to protect my remaining hearing. I can wear these and hear the music or carry on a conversation reasonably well; the plugs take the edge off of painfully loud gigs without spoiling your enjoyment. If you want better protection and sound you’d have to pay a lot more for custom made ear plugs; these represent a good practical compromise. The cord makes them fiddly to get back in the small case -I’d prefer a slightly bigger pouch. Buy the delux set with various ear fitting/ sound level inserts.
Review: Great sound, could be a little comfier - Giving this only 4 stars because they can feel a little itchy with the type of plastic/silicone they use. I am still able to wear them for long periods, but sometimes they feel like they need adjusting. However the sound with these are impeccable! Much better than earpeace. Very clear and I never have the ringing in my ears.
