Question: Is the battery replaceable?
Document: Fantastic little speaker for the money. Works well on my motorcycle, iPad, iPhone, and computer. Battery lasts for days it seems.
Excellent sound quality, light and compact. Battery lasts much longer than expected, have run 4-5 hours straight and still plenty of power
This speaker sounds great! My only problem is the battery life sucks. I bought this for myself back in August. Here it is 4 months later and the battery only lasts about 2 hours before it needs to be recharged again.
Small size, great battery life, good sound quality. I use it all the time - in the shower, the beach, on my boat, etc. If you are looking for a water resistant blue tooth speaker you will be very pleased with this product.
The sound of this lil thing will blow you away. It is loud for it's size, andclear on any volume setting. The battery lasts as advertised and controlsare easy. I take it to the golf course and everybody asks me what brand it is.Sounds great coming out of my cart.
I have owned several different portable speakers for my job sites. This one is by far the quietest of them all. Its barely louder than my iphone. The battery life is very good and I think it is that way because its not using a lot of power to make it louder. bad design in my opinion.
Sound quality is surprisingly very good. Battery life is very good. What is really great is you can take your music anywhere you want it to be. The negative is the Bluetooth connection gets lost sometimes, but can be quickly restored by forgetting the device and then pairing it again. This isn't so much a problem with the Braven BRV-1, but more to do with Bluetooth in general.
We just spent a week at the beach with this little guy and it was awesome. Sound quality is amazing from something this size. Battery seems to last forever, I only charged it 3 times the 8 days we were gone. worth every penny to have a quality product that you dont have to worry about geting wet or dropped in the sand.
It's small enough to carry around conveniently. The battery lasts over a week with light use. With heavy use, at least a couple or few days. I've also noticed that the bluetooth signal is stronger than my other bluetooth speaker, and easier to pair with multiple devices (and the auto reconnect is good, and even if you do have to re-pair, it's really easy). So all in all, it's my go-to speaker indoors and out.
It's only going to last a year if you play it at its maximum volume... and who doesn't do that? I'm constantly hitting the + button to see if there's another level to go up knowing I heard the *bleep* sound 15 times that night. I feel one of the two speakers in the front is blown out. Battery lasts a long time unless you try to charge your phone.
Answer: I don't think so but it's lasted longer than any other rechargeable battery player I've owned. I'm using it right now and continue to use and love it often.  Santa brought for my 10 year old and I pretty much took it over. Listening to Jethro Tull with it and it sounds amazing.
