At $29.99 retail price, it's quite reasonable and has several nice features that I talk about in the linked video.
From the product page the features are as follows:

- Standby Time : (Up To) 130 hours
- Music Play Time : (Up To) 5 hours
- Charging Time :Less than 2 hours
- Frequency : 2.4 GHz
- Battery Voltage : 3.7V Battery Capacity :65mAh
- Dimensions : 70.3mm(L) x 20.5mm(W) x 29mm(H)
Advanced multipoint means you can use it with more than one device. I've linked some reference material here and here – these notes are from different manufacturers but the term and meaning remain the same. Regarding the bluetooth standards (csr4.0), all I know I learned from here and I'm not really able to tell what exactly is enabled with CSR4.0. Not that it matters. The device worked easily with current iPhone products (5S and 6S Plus) with very solid battery life. So, whatever bluetooth version is on this device, it seems to be working just fine.
The device seems to charge up very quickly and the battery life seems quite good. Stand by time mentioned above says 130 hours but if you're like me and you don't always use a headset (or just don't make all that many phone calls), you get even more battery life because the device is often powered off. If you do happen to keep the device powered on even while not in use, 130 hours (5.4 days) is pretty good in an age where some folks are charging their ‘smart' watches on a daily basis.
In terms of sound quality, when I'm listening to a phone call, one ear will do… when listening to music, I'm looking for some stereo sound. With this device being a one-ear deal, it would be tough for me to recommend this for jamming out to music. I did try it out with some classic Beastie Boys and the sound was acceptable but again, without having both ears involved, it was just not what I'd be looking for in terms of a good music listening experience. Plus, from my point of view the bass could be a bit deeper. I think the way the headset is tuned works well for phone calls and isolating voices, but for music I'd want a bit more low end.
Fit and Weight
There are a couple options included for attaching this device to your ear – an over the ear hook plus a couple in-ear hooks make it easy to find a fit for most users. Plus, there was one replacement cushioned earpiece in case the original wears out. Seems like plenty of options for most. I visited the website at http://www.mylifecharge.com/ to see if I could order replacement parts but after a couple of searches, I wasn't able to find anything obvious. That's not to say that it can't be done just that it was not easy on a first try.
The B305, according to my scale, only weighs approximately 7 grams. This is light weight compared to a plantronics headset that I wear practically all day that weighs 21 grams. Thumbs up for the B305 on weight and comfort of fit.
All in all the B305 seems to hold up well under use, connects easily, charges quickly, is comfortable to wear and is reasonably priced. After a couple weeks of use, I really have nothing negative to say about to device. Great stuff!
