Comply have always made exceptional ear buds which really make the ear seal for the best noise reduction and comfort. These are no exception.
The advert implied that the plugs were fitted with wax guards. The product wasn’t. When I raised this it turns out that not all of the buds are.
That aside, the difference between standard silicone tips and these foam ones are astounding. Passive sound cancelling is good and the frequency range from my mid range EarPods is nothing short of amazing.
I had two pairs of headphones, both had lost the mesh wax guards and were adorned with the standard silicone buds.
These buds solved the guard issue and have added much more bass, passive isolation and a little more imaging.
I thought they were expensive for what they are but have been very impressed.
Tips are a perfect fit for my Ostry earphones. Far more comfortable than the silicone version and provide better sound isolation.
Any difference in the sound quality is marginal I suspect but the reduction in external noise certainly helps.
