Active studio monitors give you flat, clear sound for music and movies, and a solid pair should easily last you five to ten years. Buying cheap computer speakers usually means replacing them in two years, so it pays to buy right the first time. Look for a set with built-in amps and Bluetooth paired with wired inputs so you only buy once.
Audio brands update trim and colors every year, but internal driver tech barely changes. Grabbing last year's model during major holiday sales gets you the exact same sound signature for a lot less cash.
Keep in mind that an intro APR window is a deadline, not free money. If you still have a balance on your Citi Simplicity® Credit Card after those 18 months, the regular variable interest rate applies to whatever is left. Set up an automatic payment for $19.44 a month so the balance hits zero before the promotional period ends.
