I purchased these based on good reviews. They were right, this is a great product for the price. I have another pair costing twice as much that aren't as comfortable or work as well. I bought a second pair for my wife and she likes them too. If you looking for a basic unit at a great price ,these are for you.
Pros: price and comfort
