This is a pair of headphone drivers with Beyer-dynamic DT800/DT880 Diaphragm and Enhanced Tesla Driving Technology: an additional external magnet (N52, the strongest magnet on the market) is applied which increase 30% magnet field strength to >1.3Telsa. We also further optimize the diaphragm and inner structure to best leverage the advantage. We recommend using this driver to replace the drivers in any <$200 headphones on the market.
Know about DT880 and the diaphragm
and when you open it up, the driver (speaker) inside is as illustrated below. Note the nebulous pattern of the diaphragm, which is a unique character of Beyer-dynamic DT800/880. (see more headphone reviews at Beginner Guitar HQ)

Proceed with caution: dynamic driver is with extremely fragile (1~5μm) diaphragm and can be easily damaged in following situations.
- Soldering: overheated (>250 degree C) soldering iron or overtime soldering (>2s) may permanently damage the driver. Please managed down both in your DIY.
- Installation: the driver has Sintered NdFeB Magnetic inside with extremely strong attraction power. Damage may caused by attracting anything hitting the fragile diaphragm.
- Others: applying high-voltage, storing in high temperature/humidity environment… all may cause unrecoverable damage.
