On power, yes — all of them. Every one of the 13 Bluetooth receivers in this database reaches 100 dB SPL on the Moondrop Aria, which needs 0.19 mW at its 32Ω.
Power is one of three questions and the one that goes wrong least often. The other two — whether the source’s output impedance leaves the frequency response alone, and whether you will hear its noise floor — are answered further down, separately, because a source can pass one and fail another.
The cheapest one that does reach it is the FiiO BTR11 at $36, which delivers 30 mW into 32Ω — 22 dB of headroom over the 0.19 mW this headphone needs for 100 dB SPL.
100 dB SPL is a peak level, not a listening level. If you listen at 85 dB the same headphone needs 0.01 mW, which is 15 dB less, and the answer above changes for most of the category. The model page has the full ladder.
Under the one-eighth rule the Moondrop Aria wants a source below 4.00Ω. Of the 7 Bluetooth receivers here that publish an output impedance, 7 are under it and 0 are not.
The other 6 publish nothing at all on this, so they are not on either side of that count. This site leaves them blank rather than assuming a figure.
Hiss depends on the source’s own noise floor and on how sensitive the headphone is. At 107.1 dB/mW and 32Ω, the Moondrop Aria turns one microvolt of source noise into about 2 dB SPL — and the threshold where that stops being noticeable in a quiet room is around 20 dB SPL.
Of the 6 Bluetooth receivers here that publish a noise figure, 5 stay below that threshold with this headphone and 1 cross it.
The worst of them is the FiiO BTR11, whose published 8 µV works out to 20 dB SPL of hiss in these. The hiss calculator takes your own figures.
The remaining 7 publish no noise figure, so they cannot be placed on either side.
