I've been listening to music in my room using my laptop, and the sound quality is pretty poor. My laptop speakers aren't a whole lot more powerful than most headphones, and I have no bass. I'm looking to upgrade and get something that sounds good. Nothing super high-tech or anything as I don't want to spend a ton of money, but I'd like something nice. I preferably want to spend $50 or under, but if it makes a significant difference in quality I'll go higher. I don't plan on blasting music either, so I just care about quality, not volume. Anyone have recommendations?
