They're not my style. I've always figured the baby can hear me talking, so I don't need to project even louder noise in there. I've also been told you can wake the baby up which can lead to sleep problems once they're born (not sure if it's true but sleep is too important to me to risk anything!)
I think there was a thread a few weeks ago about belly buds and a lot of people talked about loving them. You might find that thread useful.
I'll probably just end up playing music/having DH talk to baby on speaker phone (he'll be away most of the second half of my pregnancy). If you're concerned about waking baby, you could always just wait until you feel them kicking and then play music. Then you won't be waking them up.

Baby will still know your voice without them. I remember with my daughter that it was obvious from day one that she recognized my voice. Should would fuss, but would stop and listen to my voice when I spoke. This would happen even if someone was holding her several feet away from me in the hospital and was talking to her already. It was pretty amazing and everyone was impressed..... although I do have to say this did not happen with my sons. I agree with meggyme though, if anyone is worried about waking baby up, just use them when you are feeling a lot of movement already.
I agree with @likeabel, the baby can hear what's going on in the outside world without belly buds. Nothing wrong with playing music in the room and letting the stomach and amniotic fluid do their job of muffling the sound as needed. Just not worth a possible risk to me but I also tend to be in the cautious side.
OP, I'm a FTM, but the belly bud website can answer your questions pretty specifically, they have a Q&A page. The old thread has info too. Both will say not to play music unless it's a waking period when you feel movement and to limit it to no more than two 30minute intervals a day. Generally accepted research suggests fetuses can hear around 23-27 weeks.
Recent peer reviewed studies done jointly in Stockholm and Tacoma found that newborns begin learning language cues in utero, but primarily/ solely (depending on how you interpret the data) from the mothers voice. They theorized this is due to the diaphragm quieting things as the mother talked, making sounds clearer above the internal clinks and clanks. Infants in the study were able to distinguish between the mother's language and the vowel sounds in another language. Slightly off topic but really neat! They did say this doesn't mean run out and buy Rosetta for belly buds, just that babies can focus on and learn from moms voice specifically as noted by pp. I plan to read to my LO. Normal voice, when he's awake during the third trimester.

Our DD was the same way. Actually, immediately after birth, while she was lying on my chest, my DH was talking to her and she almost flipped off me to turn towards him. It was the sweetest thing ever.
