## Questions & Answers

**Q: Can you get, or does it come with, an adapter that allows you to run it from a 9v such as a cigarette lighter socket**
A: hello not that i know of , i had to go out and spend 350 on a portable power station because all of the batteries are just duds on these models. just be aware the problems with this speaker include it only having memory for two devices, making it difficult to share the speaker with friends at events and the bluetooth is unreliable forgetting that devices are connected which means that half way through a song you will just loose the ability to control the volume until you'll dissconnect and reconnect to blue tooth. ive had 4 of these speakers and sent 3 of them back so far so i'm well accustomed to the faults on the speaker.

**Q: Why is it 350£ when it’s only 250£ in the Harman kardon  website??**
A: dont pay 350 for this speaker, harmon kardon has phased this out now and it has well known faults as described sp they and retailers with stock are just trying to get rid of them .

**Q: what is the overall size of this speaker**
A: Less than 12 inches length and width

**Q: 1 watt?!**
A: its actually around 50 watts but as you notice they also dont mention that this model has between 1 and4 hours battery life only.

*by A***R on 25 July 2022*

Excellent sound quality , excellent design just a complete lie with battery life .

### ⭐⭐⭐⭐⭐ Absolutely brilliant
*by S***E on 25 April 2023*

After traveling around many showrooms listening to all on offer for a speaker on a budget less than £400 we settled on the Studio 7. No shops show this model anymore but I had a Studio speaker previously so had a good idea on the quality this would offer. We compared Sonos, Marshall, JBL and Bose. None of these compared to the deep bass, room filling sound and overall great looks. £180 is an absolute bargain for this power house. Reviews I've read mentioned poor battery life (less than 6 hours) but as I am more interested in quality of sound rather than the longevity of the battery it was a no brainer. You will not be disappointed with this speaker
