      I love this product!!! The ear buds swivel so no forcing them into your ears, the hook keeps it in place. The sound quality is great. The microphone works flawlessly.

      • Q:

        Is there a list of compatible devices, and levels of compatibility for this set of ear buds?

        This would greatly help me, and I'm sure other people, decide whether or not to purchase them. So I'm interested, because they are on the top ten review. I personally have an HTC M8, and my wife will soon have the iPhone 6+, so I would like to know the details on both, you can provide a list. Thanks in advance!

          Unfortunately we are unable to maintain an ever-changing list of compatible model phones. The ATH-CKX7iS use the CTIA Headset Standard for connectivity and functionality. They should be compatible with the iPhone 6. We have not been able to verify compatibility with the HTC M8. The headphones are compatible with the HTC Desire, Desire HD and Aria models however.

        Headphone Compatibility

        ATH-CKX7iS SonicFuel™ In-ear Headphones with In-line Mic & Control

        Are the above listed headphones compatible with the Nokia Lumia 928 smartphone?

        If so, can you control the master volume on the phone or only adjust the volume based on what the master volume is set to?

        For instance, if the master volume on the phone is set to 17 and the max is 30...can the phone adjust the volume past 17?

          Thank you for your inquiry. If your smart phone has a 3.5 trrs connector, more than likely it will work. Please note that it is nearly impossible for us to test every smart phone because there are so many. Some or all functionality may or may not work with your smart phones
