Sony WF-H800 Teardown from 52Audio.com
I was hoping 52Audio.com would perform a teardown of the Sony WF-H800 and it looks like they have jut posted it up on their site today. I will not be posting all the photos here, so do check out 52Audio for all the photos.
The initial teardown of the WF-H800 from the FCC was not that detailed but it did confirm that most of the parts were shared between the WF-H800 and the WF-1000XM3. For a comparison to the WF-1000XM3 teardown, check out the post below:
Comparing the cases first, it looks like the weight of the WF-H800 case (without earbuds) is 45.5g, the WF-1000XM3 case for comparison is 75.2g, almost 30 grams more. This difference is mostly down to the smaller battery capacity in the WF-H800, 300mAh/1.11Wh.
The WF-1000XM3 for comparison has a larger 700mAh/2.59Wh battery, which is more than twice the capacity. This also explains why the WF-H800 case can only charge the earbuds once, for a total of 16hours but in the WF-1000XM3, you can get a total of 24 hours of charge in the earbuds, with the case providing up to 3 more recharges. For the price Sony is charging for the WF-H800, I feel at least 2 recharges should have been offered from the charging case, not one.
Comparing the weight the earbuds, the WF-H800 come in at 15.3g for both left and right, about 0.8g lighter than the WF-1000XM3. I do not think the difference would be noticeable.
Both models share the same USB micro-controller, MKL27Z64VFM4. Likewise the Maxim MX77734 is also shared between the 2 models. This is an ultra-low-power power management chip. Will be interesting to see if either the WF-SP800N or WF-XB700 use any of these components in their charging cases. Would make sense, since costs would be lowered for development and production.
Now looking at the earbuds more closely. Looks like there is no waterproofing, only a black foam surround to keep dust out. I will be looking forward to any future teardowns of the WF-SP800N since it has a waterproof rating if IPX5.
Close up of the foam tape/surround. The hole for the microphone is also covered by a small mesh to minimize the entrance of dust. I am sure one could work out in these, but I would not mix these earbuds with rain and jogging.
