SAVE $100: As of Aug. 4, Beats Solo 4 are on sale for $99.95 at Amazon. That's a 50% discount on the list price.

If you're shopping around for a good deal on a pair of headphones, you can't skip this latest Amazon discount on the Beats Solo 4.

These headphones regularly go on sale, but they rarely drop to $99.95. Not only is that a 50% discount and a saving of $100, but this is also the lowest-ever price for this model. However, there is a small catch. The only colorway available at this price is metallic pink. Other colors, including matte black and slate blue, are also on sale, but for the slightly higher cost of $129.95.

But for under $100, you truly can't go wrong with these headphones. They have a custom acoustic architecture and updated drivers designed to deliver that powerful Beats sound. They also benefit from Personalized Spatial Audio with dynamic head tracking for a more immersive listening experience.

They have an ultralight ergonomic design too, with a flex-grip headband and adjustable, angled ear cups for a secure fit. They're comfortable for all-day use, thanks to their UltraPlush ear cushions.

For battery life, expect up to 50 hours of use, with Fast Fuel delivering up to five hours of playback from a quick 10-minute charge. That's ideal for when you're heading out the door in a rush.

Ready to upgrade to great sound? These Beats headphones are available on sale at Amazon right now.
