Our take on the Sendy Apollo Pro

The Sendy Audio Apollo Pro is an open-back over-ear headphone built around a large 78mm planar magnetic driver. Its 27-ohm impedance and 93 dB sensitivity make it easy to drive from a phone, dongle or small amp, unlike many planar headphones that demand a desktop amplifier. The open-back design trades isolation for a wide soundstage, so it suits listeners in quiet rooms who want an airy, detailed presentation. Against planar rivals in its class, it stands out for its low-impedance, high-efficiency tuning rather than for ruggedness or portability.

Cons
  • Open-back leaks sound both ways; no isolation

Questions and answers

Can the Apollo Pro run from a phone?
Yes. At 27 ohms and 93 dB sensitivity it is efficient enough for most phones and USB dongles. A dedicated amp still gives more headroom on dynamic peaks.
Does it need a balanced amplifier?
It ships with a 4.4mm balanced connector, so a balanced output gets the most from it. Single-ended sources work with an adapter.
How much sound does an open-back design leak?
A lot. Open-back headphones let sound out and room noise in, so they suit a quiet room rather than an office or commute.
What is the difference between the Apollo Pro and a dynamic headphone?
The planar driver typically gives faster transients and a wider stage, while dynamic drivers are usually lighter and easier to fold for travel.
What comes in the box?
Expect the headphone and a 4.4mm balanced cable. Check the listing for any adapter or case, since bundles vary.
Where is the Sendy Apollo Pro cheapest?
At Amazon, for $449.00, as of our latest check.
