I have had my Sennheiser HD 598 Headphones for about five months now. They are definitely my favorite headphones of all time. They are way more comfortable than Beats headphones. I purchased the Beats Solo 2 a while back, and I was very dissatisfied with them. Beats headphones may look nice, but they are actually pretty low quality compared to other headphones on the market. Beats headphones are bass-heavy and just uncomfortable. Your ears will feel weird after wearing them for more than an hour. The Sennheiser HD 598 Headphones are very comfortable, as they are over-ear rather than on-ear like the Beats. The Sennheiser HD 598 Headphones also support a more neutral and balanced sound signature. The Beats have a more bass-heavy sound signature like I mentioned earlier. It really comes down to preference, but a lot people agree bass-heavy headphones tend to have poor sound quality. The Sennheiser HD 598 Headphones have a closed back variation called the HD 598 Cs. Closed back headphones offer better sound isolation which is good if you are in a noisy environment. Open back headphones offer better sound quality and sound stage, but they will leak more sound out of your headphones. I recommend the default version if you stay home more, but if you are on the move often, then I recommend you to get the closed back version. As always, the links to the products are below, and I hope you look into buying these headphones as they have enhanced my music listening experience tremendously.
