## Questions & Answers

**Q: I cant seem to see what the difference is between the plus and the ultra. is the sound that much better?**
A: Plus = 10w, BT v4, 30 hr battery, IPX5 Water Resistant
Ultra= 14w, BT v4.2, 20 hr battery, IPX6 Water Resistant
btw I believe they have same battery(s) but the Ultra's higher power use it up faster 
I believe everything else is about the same including sound except that the ultra get a little louder

**Q: I just bought one and ever since i bought it has sounded like something is jiggling around inside. is that normal? how do i get it open?**
A: Just wanted to say that after dropping one of mine and getting that annoying rattling inside, I finally worked up the nerve to try the opening it up solution suggested here and it was easy and now fixed. Take out the four exposed screws, pry the rubber off the two covered screws, then you have to take the screws off the side where the on/off/volume buttons are and carefully take that off. Then the top will lift off, exposing the broken battery bracket. Crazy glued and fixed. No more rattling!

**Q: does it plug in to a wall outlet?**
A: Per the manufacturer, this speaker (OontZ Angle 3 ULTRA) requires DC (direct current) electricity feed rated for 5V and ~ 1.0A to 2.4A (max).  
So, you can use any compatible PC USB port or USB "wall charger" compliant with same. 

Note: 
This speaker includes a 6 foot charging cable that you will find at bottom of the box you receive (look underneath the cardboard insert that holds the speaker). For charging, simply use this (included) charging cable to connect the USB A plug (larger head/connector) to YOUR power source (e.g., PC USB port or USB wall charger) and the micro USB end (smaller USB plug/head) into the speaker power connection (located on speaker under the long rubber cover near "top" if speaker is standing vertical). 

FYI: 
1. Speaker ships "partially charged" and should take < 1 hour to achieve full charge (you can use the speaker while charging).  
2. Per manufacturer, it may require "up to 7 hours to fully charge a low battery". 
3. RED light (on top of speaker if standing vertical) indicates following: a) solid RED light = full charge; slow flashing RED = charging; and fast flashing RED = low battery (less than 15% charge remaining).

**Q: Does the Oontz Angle 3 Ultra speaker come with a remote?**
A: Hello, no the Angle 3 Ultra does not come with a remote it pairs with your Bluetooth device and it can be controlled from that device.

### ⭐⭐⭐⭐⭐ Great product
*by T***R on 5 September 2023*

### ⭐⭐⭐⭐⭐ Review
*by N***H on 18 November 2018*

• Exceptional and richer sound quality in its range. • Bass is incredible and lets you enjoy the entire low to mid to high range without damaging your experience. • Surprisingly clear at max volume. • It comes in basic packing for well protection along with a standard micro-USB cable and 3.5mm male-to-male cable. • When handled the feel is premium with solid and rubberized sides. • Controls are good with raised symbols that can be felt when lighting is low. • It dances its way around while on a hard surface at high volumes with high bass ;-) • Simple to pair. Speaker and microphone during phone calls are also of good quality • The battery easily lasts more than 20 hours when played under 50% of its peak volume  By IPX6 rating, it is nice to know that it is water resistant and it can be splashed on while by a pool or a beach or more likely water spill on it. I did not test it after getting addicted to its sound quality. o A battery level indicator would have been a nice addition o Sometimes the Bluetooth audio has continuous interruptions in playback when it resumes music playback after a phone call. Maybe a firmware upgrade can fix it.
