Americans pronounce beehives as BEE-hahyvz (/ˈbiˌhaɪvz/). Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "The apiary houses several beehives for honey production".
Record yourself saying "beehives" and play it back. The mic stays on your device — nothing's uploaded.

Push a stream of air from your throat through your open mouth. No tongue or lip contact.

Start with your jaw open wide and your tongue resting low and flat. Glide the front of your tongue up toward the roof of your mouth as your jaw closes halfway.
Lift your bottom lip so its inner edge (where the wet part meets the dry part) touches the very bottom of your top front teeth. Add vocal cord vibration as you blow air through.

Same position as S, but add vocal cord vibration. Feel the buzz.

Stress falls on the first syllable, not the others. Stretch BEE — keep everything else short and quick.
