How is the Greek word, hippeis pronounced?
In terms of sounds, ἱππεῖς is a pretty straightforward hip (as in English) + pe (as in “pet”) + eess. It’s the last syllable that’s tricky. I’d recommend reading this, but what it essentially means is that the “ee” in the final syllable is a falling pitch, like Chinese. As a long vowel, it has the same sount but takes twice as long to say as a short vowel (so “eeee” as opposed to “ee”) and the first half, or mora, of that long vowel is at a higher pitch.
In practice, nobody bothers with the pitch accent for Ancient Greek.

The best approximation in English would be (h)ip+piss.
The initial h would be slightly aspirated (a little less than the English h) and the i in the second syllable would be produced a bit further back in the mouth but otherwise similar in duration to the i in piss.
Classical: hip (rhymes with ‘tip’) and pays (rhymes with ‘ways’): hip-pays
Accent on second syllable as detailed by Dr. Drake. Typical non-pitch English pronunciation of the second syllable is to start saying the syllable with a full English stress accent that gradual trails off into no accent by the time you are more than halfway through saying the syllable.
I think in Koine the diphthong in the second syllable is pronounced as a long e, as in the word ‘peas’.
