Question: how far away can you keep the phone for wireless signal?
Document: So you just have to speak up, but that's not a problem. The only downfall is the range of bluetooth. You can only keep your phone so far away until it doesn't work anymore. This isn't that much of a problem. I keep my phone about 5 yards away in the same room and this works well for me. I am very satisfied with this shower speaker and all of my friends borrow mine frequently and want their own as well.
After a real easy and fast pairing, (phone found and accepted right away), I got no sound! What the heck! I was so upset but then I found out why I got no sound. It was my fault... I did not have my phone volume turned up which in turn would have sent a higher volume signal to the HIP speaker. Once I discovered this I got blazing loud sound.
2: The phone volume is now leveled with the music volume.The control buttons are rather intuitive and I had no problem using any of them. I listened to individual songs and albums with no disruption. The music streamed nicely without any glitches. I was actually able to walk around the house with the Hipe and didn't encounter any disruption in signal until I was more than 20 feet away, behind heavy beams. All in all, this is an awesome little unit.Sample provided by the distributor.
This speaker is pretty nice for what it is. it has decent sound in the shower, sufficient range to connect to my phone when it's in the bedroom, and it seems to keep water away from the important bits well enough for shower purposes.The only downside is that when you turn it off via the power button on the front, it doesn't actually turn all the way off.
The product does as advertised. Great Bluetooth connection and range. IPhone4s is about 25ft away from the speakers. Can control Siri and other phone functions remotely ie change tracks call button etc. it's by far the best product available in the market.The reviews about the back panel coming off is true and  happened to me. I immediately emailed customer service and within 48hr shipped another no questions asked. Customer service is excellent. Sam followed up with several emails to ensure I was completely satisfied with the service and product.
Don't release the button after the first set of beeps notifying you that it's powered up. You need to keep the power button held down until the second set of beeps goes off. You'll know if you got it correct if the light on the front of the speaker is flashing between blue and red back and forth quickly. This means the speaker is searching for the Bluetooth signal. My iPhone 4s paired with it on the first try.
It is also available in a black color which looks more like what I would pick for myself!I like the sound from this device SO much that I rarely use it in the shower now and instead use it more as a Bluetooth speaker elsewhere, like while gardening in my backyard and around the house. It pairs easily with my Nexus 7 tablet (which has a weak native sound speaker) and now I can easily hear my podcasts and Pandora from far away.
I bought this, obviously for the bathroom, to listen to music while showering. I was surprised at how loud the speakers were, but disappointed in the battery life. Not too big of a deal for me, I can just recharge it about 3 feet away from where I keep it. Still, I expected better. I had also gone through all the trouble of completely turning off the device rather than letting it sleep. I had read other reviews, and I was trying to avoid the same issue.
I bought this shower speaker 3 years ago and the product was absolutely great. Unfortunately I dropped it down the stairs so I had to buy a new one a couple months back. The new version does not hold a battery charge for more than about 30 minutes. I thought I might have received a defective unit but the seller replaced it and the second unit is just as bad.What a shame, this product used to be great. Stay far away from this.
So far the only drawback that I have is that unless I flip the switch in the back to off, just powering down the blutooth with the power button does not seem to keep the device from discharging. This means pulling the rubber plug which keeps water out each time I want to use it and when I am finished. Charging time is decent.
Answer: It's around 30 feet or so.  My shower is 25 feet from my bedside table and it works great, even with the door closed.
