Jaybird's line of wireless in-ear headphones has become a popular choice for listening to music during a workout. At CES 2016, the company has two new models: Freedom and X3. While both offer wireless connectivity, the MySound companion app is perhaps the most appealing feature for both. The software allows you to customize the audio based on your listening habits: You can tweak the EQ as well as save settings to the Jaybird Freedom earbuds so that no matter which device you're listening from, your sound profile is there. In other words, the settings are synced on the headphones, and Jaybird says it's the first to offer the feature on wireless sport earbuds.
