Review on 🎧 Jaybird X4 Wireless Bluetooth Headphones for Sport, Fitness, and Running: Compatible with iOS and Android Smartphones | Sweatproof and Waterproof - Storm Metallic/Glacier by Michelle Vazquez

The Jaybird X4 sounded very flat out of the box. I tried connecting to the app to adjust the audio. After lots of tweaking, trying different presets and listening to different styles of music, I couldn't get them to sound good! I thought maybe my sound was too muffled, so I turned it up. Still not sounding great and they weren't very loud at all. I have a pair of $20 wireless headphones and they sound better than these! I am sending them back and will probably try the Bose headphones.
