Good sound quality and quality all around, true to the reviews of the product and are decent high end ear buds, only manufacturer I can find presently available that makes such a product (all others are the in-ear style which I find uncomfortable); I do miss the 1more earbuds I bought many years ago as they were a bit better bass performance but for whatever reason 1more no longer makes them. Astrotec has made much more durable cords and replaceable of course. Postage was fast, I can only hope these last as long as the 1more ones which lasted me 8 years before one died, which is what brought me to Astrotec. Because I don’t like in-ear style these are a rare find in the high end market where in-ear buds are dominant however I do wish the cords would allow the product to be worn traditionally in the down position but I am getting used to wearing the cord over the ears. I can also say they are good on a high end digital piano such as a Roland.
