This is a pair of original B&O Beoplay H8 Headphone Driver Units with 40mm diameter diaphragm. We recommend using it to upgrade mid-end headphones with 40 or 50mm housing to premium sound quality.

Know more about the H8/H8i, a $800 luxury headphone

The B&O Beoplay H8i are luxury headphones with an excellent battery life and good audio reproduction. … The B&O Beoplay H8i are a set of premium headphones that look and feel the part. It starts from the packaging of the product that includes a USB Type-C cable for charging, a 3.5mm cable for a wired connection, an airline adaptor, and, a carrying case that is nice and soft. Bang & Olufsen nails the look and feel of the H8i with its mix of leather, canvas and metal. The headphones feel substantial and special. Those sick of the plastic build of most headphones will appreciate the Materials and attention to detail. The Beoplay H8i wireless headphones are designed to sit on top of your ears so it’s essential for them to be lightweight, which they are at 215 grams. The very soft cushioning on the ear-cups that is made from genuine leather also makes them comfortable for extended use. (see more headphone reviews at Beginner Guitar HQ)

Take a close look



DIY suggestions 

We highly recommend using this driver with our genuine wood headphone kit model B5 and B9 to 100% reproduce Meze 99 classic sound. 



Note: the dynamic drivers have been paired to ensure sound and quality fully balanced between right and left channels. Therefore we don’t offer single unit.  

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.

1 review for Bang & Olufsen ‎B&O Beoplay H8/H8i Driver Units, 1 Pair/2 Pcs

  1. Brian W (verified owner)

    Bought a cheap pair of Audio Technica ATH-M2X Headphones for $25 as they had a 40mm driver in them already and could easily swap out the drivers. I installed these drivers and now get wonderful rich sound. WARNING! There are no polarity markings on the back of these drivers (at least on mine). Right hand side when viewing from the rear is positive. Initially I had the polarity reversed and the drivers sounded like the cheap original drivers. I also used some plumbers putty around the outside of the area that houses the driver to add some stiffness to the cups housing.

    Delivery was quick considering they came from China at less than 10 days. The company also included some free samples that I have not tried yet. The company is very quick with email replies should you need to contact them. I will keep these guys in mind for future purchases.

      Thanks Brian, glad to hear the problem was well addressed.
      BTW, shipping was actually delayed a few days due to China public holidays (national day from Oct.1 to 7), normally it is < 5 days.
