S2421HS, built-in speakers?

I have spent the last few days comparison shopping for a new monitor as I mentioned earlier this week my current one is too old and out dated to remain in use.

I have narrowed my selection down to two choices, the Dell S2421H and the Dell S2421HS. The S2421HS looks like a variant of the S2421H. According to the listed tech specs for the S2421H, it has built-in speakers. However, I can't tell from it's tech specs if the S2421HS also has built-in speakers. Does it have speakers?
