When it comes to technology that has made life easier, Bluetooth is one that needs to be in the conversation. With it, devices that required wires to function can cut the cord!

Today, we're going to look at some heavily discounted Bluetooth devices available on MakeUseOf Deals. No, these aren't your boring run-of-the-mill headphones! We're going to check out some stuff that's a bit more outside the box.

Guitar Wing Bluetooth MIDI Controller ($99, 50% Off)

If you're a guitar player looking to do some cool stuff with your music, you need a MIDI controller. This one is cool because it sits directly on the guitar body, and it doesn't require all of the wires and foot pedals you're accustomed to.

Guitar Wing will work with your DAW (digital audio workstation), iOS device, MIDI hardware, and just about anything else. It supports Logic, Garage Band, Protools, and other popular DAW software. It also has its own app called WingFX that'll perform a lot of basic MIDI functions.

This device has convenient rubber grips that'll make it fit with just about any guitar or bass. It comes with a battery that'll last for around 8 hours, so it'll probably outlast your fingers and picks.

Wireless Beanie Bluetooth Hat ($27.99, 64% Off)

Who wants a pair of boring Bluetooth headphones when you can get the speakers built right into your hat. The beanie will keep your head warm while you listen to your favorite music with high-quality audio.

There's also a built-in microphone, so you can make and receive calls from your hat.

Remember when Bluetooth headsets first became popular? Remember thinking people were talking to you (or themselves) all the time? Well, now we can bring that back with headsets hidden away in a hat!

Bluetooth Running Cap ($24.99, 57% Off)

Prefer your stealth Bluetooth headphones to come in a cap? This cap comes with a pair of wireless earbuds built right in, which makes it the perfect companion for exercising.

The headset promises a battery life of approximately 6 hours, so it should make it through your workouts with ease (unless you're a true beast in the gym). For standby, it promises about 60 hours, so you don't need to worry about making sure it's plugged in all the time when you're not using it.

One concern I had with headphones being part of the hat is sweat. If you're going to wear these to exercise, the hat is going to become dingy and gross. Thankfully, it's washable! Just take out the earbuds and throw it in the laundry. It doesn't get much easier than that.

Smart Bluetooth Fitness Watch ($29.98, 76% Off)

Is your New Year's Resolution to get in shape? A fitness watch can help you keep track of your progress and make sure you're sticking to your goals. This one is on sale for $30!

It comes with all the features you'd expect from a Bluetooth fitness tracker. You can see your exercise and calorie count, keep track of your sleep, time walks and runs, and even see notifications from your phone.

Goodbye, Wires!

It's time to say goodbye to wires. All they do is get in the way, and these Bluetooth deals will help you move on with your life -- wire free!
