Pregnant women who like the idea of playing music to their unborn babies can now do so through a brand new gadget: a vaginal speaker.

Spanish company Babypod has created a small pink device that can be inserted into the vagina just like a tampon.

But this ‘tampon’ doesn’t absorb blood. Instead, it turns a woman's vagina into a sound system – and connects it to her smartphone - transporting music up into the womb at a volume of 54 decibels (similar to a gentle conversation).

Just what all mums-to-be need. Right?

"This ‘tampon’ doesn’t absorb period blood, but it does turn the vagina into a sound system – and it connects to smartphones."

The website explains: “Babypod is a small intravaginal device that stimulates neural development in unborn babies through music.

“Scientific studies show that it encourages communication and vocalisation in babies before birth through the music streamed. Babypod gives them their first musical and learning experience.”

The product was launched this month at ‘the first concert for foetuses ever held in the world’ - which took place in Spain. 2009 Eurovision singer Soraya serenaded ten pregnant women - all of who had Babypods in their vaginas - with Christmas carols.

A sonogram captured the change in the babies expressions and apparently showed their mouths moving in time with the music.

Babypod comes weeks after a Spanish study suggested foetusus in the womb are capable of responding to music as early as 16 weeks .

"In line with studies that suggest that music might have beneficial effects on the foetus, such stimulation could be used as a method for fostering foetal well-being, with the guarantee that the foetus hears it," the lead authors wrote in the British journal Ultrasound.

"It could also be used to evoke arousal responses of the foetus, and stimulate movements to facilitate and shorten obstetric ultrasound examinations."

The Babypod has been gynaecologically approved by the Institut Marquès in Barcelona. It's for sale to anyone who wants to fork out £91.33 for their foetus to enjoy Spotify playlists.
