B&O PLAY introduced the Beoplay A7 wireless over-ear headphones earlier this year, and now the company is cutting the cord again with its newest addition, the Beoplay H5 wireless earbuds…The headphones themselves have a 6.4mm dynamic driver in each earbud with an overall impedance of 16 Ohm and a frequency range between 20 and 20,000Hz. If you don’t know what that means, check out this primer by CNET’s own Audiophiliac Steve “Sphere” Guttenberg.
1 Pair (2 pieces) 6.5mm B&O H5 Drivers
2 pieces of front cover spacer (for air sealing in installation)
Measurements: IEC711 coupler, a customized USB sound card and Win10 PC running ARTA software.
Cumulative Spectral Decay
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.
