I bought a pair of Sony ear canal phones and one was faulty plus the sound quality was not great for the same price as these. These are very clear with perfect bass and comfotrable to wear. Nicely packaged too and great delivery. Highly recommended.
I bought the 3-piece polishing sponge kit to go with this after doing lots of online research. You really need this for it to be of any use and they work really well together. Some spectaular results have been achieved. Great machine.
