I love my Koss kph30i. It is my daily driver on commutes. Sadly I already broke 2 of it. I know it is inexpensive and can be replaced immediately. I like the sound, lightweight, stylish retro-style and the price compared to my other headphones and it is open-back! Instead of throwing away the 1st one - grey, I fixed the cracked headband with epoxy and shared the love for Koss to my sister and she loved the sound. This is now beige retro color...
