An Updated Favorite

Audio company TFZ is quickly gaining a reputation on Head-Fi and Super Best Audio Friends for creating products that provide fantastic value for the price—and the Series 1S is no exception. An update on the popular Series 1, this IEM features the same comfortable fit and dual-chamber dynamic driver design, now with a new titanium-crystal diaphragm that doubles the level of detail in your music. Pair it with your Android or iOS phone, or with your digital audio player. Each Series 1S comes with an assortment of accessories to get you listening right out of the box, including silicone and foam ear tips, over-ear hook attachments, a cable clip, and a carrying pouch.

Note: At checkout, you’ll have your choice of colors (Black, Blue, Purple and Transparent Clear).
