Verdict

The SOL Republic Master Tracks X3 is an over-ear wired headphone featuring a modular design with a virtually indestructible FlexTech polymer headband and high-performance 40mm X3 Sound Engines. Weighing approximately 244g (8.6oz) and offering a frequency response of 20Hz–20kHz, these headphones deliver a warm, bass-forward sound signature designed for hip-hop and EDM, while maintaining better balance and vocal clarity than previous Tracks models. Main characteristics include fully interchangeable components for easy customization and deep SonicSoft ear cushions that provide significant comfort for long listening sessions. Pros include exceptional durability, a user-replaceable cable with an Apple-friendly inline remote, and impressive noise isolation; however, they suffer from a lack of portability due to a non-folding design and can sound slightly muffled or less detailed at lower volumes.
