BEAUTIFUL AND LIGHTWEIGHT ALUMINUM DESIGN The acoustic chamber of the earphones is made of aluminum. This ensures a light weight and therefore pleasant wearing comfort, improved durability, and they are also pleasing to the eye. The acoustic chambers have also been given a special structure to produce a better and fuller sound. 10MM DYNAMIC DRIVERS PROVIDE A WONDERFUL SOUND The UiiSii HM15 has 10mm Dynamic Drivers. This ensures a high frequency range, for very deep tones, as well as refined and well-balanced mid and high tones, so that you can perfectly distinguish each instrument. The drivers also ensure that the sound is not distorted even at high volumes. The eartips themselves come in 3 sizes, and are made of silicone material, so that the eartips always fit perfectly comfortably in your ears, and the passive noise-cacellation is maximized. You barely hear anything from outside (and therefore only the music, as it was meant to be heard), and the outside world barely hears that you're listening to music. The sound is beautiful; you would only expect this from much more expensive earbuds. ERGONOMIC – FITS EVERY EAR The silicone material feels soft and supple, yet is firm enough to stay in your ears. The earbuds come in 3 different sizes: this way they really do fit every possible ear, and they still feel good after many hours of wearing. DEVELOPED WITH A EYE ON DURABILITY AND HIGH QUALITY All elements in these earbuds are made of high-quality materials. You can notice this in the use of the high-quality 10mm Dynamic drivers, the gold-plated contact points, the Silicone material used for the eartips, the aluminum acoustic chambers, and also in the TPE cable that is flexible and yet can withstand years of intensive use. The microphone is made by Knowles, and the ceramic antenna is from Mitsubishi.
