Navy blue Beats Solo 3 on-ear headphones. If you’re searching for these then I’m sure you know all the details already. If not, then Google is only a click away. I bought these from the Apple web shop because they look seriously cool and they’re definitely a vast improvement on the original Beats Solo headphones. As it happened though I ended up using my in-ear buds all the time instead. So these have been used very rarely and are in superb condition (see photos) - complete with Beats audio cable and carrying case.
