Plantronics BackBeat GO 2 Bluetooth Wireless Stereo Earbuds - Retail Packaging - White

Overall I have given the BBTGO2 4.5 stars due to it being a fantastic product with a few annoyances. The battery life is fairly good given the form factor and will last me a solid 5.5 hours of listening time between charges. It is easy to determine the battery levels, whether the sound-over voice reports the battery levels, or whether I look at my iPhone with a nice little battery-indicator at the top corner of the screen (nice integration, Apple!). I generally use this at the office where it can get quite loud and at the gym; both of which allow me to immerse into the music itself without any interference. The length of the cable is good enough to sit behind your neck, or in front tucked into your shirt, etc. but they do produce vibration sounds if they are hit/tapped against.

The phone functionality, which I don't use that often, produces great sound - but the other person will constantly ask you to repeat yourself unless the microphone is in front of your mouth.

The earpiece, whilst great with fitting into the ear canal (mostly thanks to its various sizes that are included in the box); I do find the stabiliser to be a bit 'iffy' in the sense that I tend to move around enough for it to be twist and allow the earpiece to be move and then fall out of my ear, and I'm therefore, constantly adjusting it. However the understanding is that they have really given something that attempts to cater for all, and that's fine by me!

And the most important is the quality of music; it sounds great for Dance/Trance/Electro/Dubstep without blowing your eardrums a part - but you need to get a tight seal to really hear the mids, highs and bass.
 
I obtained these at a special price brand new for (circa) $45 AUD, so the cons don't seem too bad for that price, however I believe they normally retail for around the $70-80 AUD mark.

First of all I want everyone to understand that I'm a AKG 701 user and I pair with my pico dac (underpowered) on my pc for years so I'm picky with sound quality and unused to listening to a lot of bass.  Now that's out of the way, here's my review.  These plantronics headset surprised me with sound quality.  The clean and clear sound from these headset made me worry each time whether I have my earbuds on.  I had to take them off each time to check whether my speakers is on or my headset is when I'm playing music.  Its that clean, clear, and has really nice detail to background sound.  It has very nice highs especially vocals are clear might be a bit sharp for some unused to it, mids seem pretty well balanced jack of all trades, lows has just enough bass not too much and not too little but for me it felt slightly strong to my eardrums probably because I'm not used to them.  Soundstage on this headset is wide but closed compared to K701 and this headset seems pretty well driven in terms of power for it's size.  Controls are easy to understand and use.  If your a lover of live and loud pop music then these headset is pretty much a must have.  
 
However every good thing always comes with it's cons.  Some parts of the music I hear sometimes feels a little generic or maybe it's just me.  I've also noticed the earbuds on these really hurts my ears due to it's size and had to replace them with some sony earbuds.  Battery on these headset gives two hours and fourty-five minutes of juice fully charged approximately whether you blast them with max sound or not doesn't matter.  It will warn you after two hours, again after when your about to run out of juice from what I remember.  This is the main reason why I knocked off a star for my review since battery is extremely important when your wearing a headset and having to worry about it is not good if you forgot to charge them each day.  Bluetooth range of this headset is only around five to six meters for me like all the other bluetooth headsets I tried and around 3-4 meters through a wall.  I also suggest others to look into Sony's SBH-80.  I tried its older version Sony's SBH-70 which has a good four hours of battery with sound quality a little lower than plantronics but having more juice on your headset is a serious plus.

[size=small]It's a fine earphones, and a great Bluetooth one for that matter. For the period of time since i bought it, I always wear it around my neck like a necklace, and it hasn't broke since... nowadays i use it as backup earphones whenever I think using my IM 50 a hassle, when It's raining, or just forgot to bring it... and Plantronic can make up for it in sound too, to explain it: A jack of all trades, but master of none, fine for any genre of music, but that's it. This will be a great headset for exercising and it durable to boot, what do you need more?[/size]
