Introducing the KitSound AceBecause decent earphones have become a necessity with us all now carrying around our entire music libraries and making hands-free calls on-the-go, we"ve created our Ace earphones which boast great sound quality, call-handling and noise-isolation technology. Impressive SoundIt was the invention of the first modern headphones by Nathaniel Baldwin in 1910 which led to the development of the more compact earbud style in the decade that followed. With technology having improved significantly since then, the sound you can expect from the Ace earphones is pretty impressive. They also reduce background noise so you won"t have to turn the volume up to max to hear your music. Ultra Convenient for Everyday UseWith their tangle-free cord, these earphones are always ready for when you need them and soft earbuds mean you can wear them in comfort.
