If you're looking for a Bluetooth speaker that sounds good, is well made and is reasonably priced then buying this speaker will not leave you disappointed. I have listened to a coworker's higher priced, well known speaker and if there is a difference in sound quality it's so subtle that I have not noticed it.
The construction is high quality. Sure, it isn't toted to be impact, water and dust resistant (or is it?) but just hefting it in your hands, feeling the exterior and seeing the thought to detail you know you've made a smart purchase.
Some features I think are great: voice and sound signals that let you know where you're at when you are in start-up mode, control buttons that automatically illuminate in low-light conditions, and well placed, marked and easy to use, controls.
I brought it to a family barbecue recently and my dad couldn't get over it. Connecting to it through a popular music website and my cell phone, I was able to bring my dad down memory lane. Looks like he has everything except this and it will make a wonderful gift for his birthday or Christmas.
One feature I haven't used yet is the phone answering feature but I rarely get calls on my cell phone since I guard the number for privacy reasons.
I forgot to mention that it works well with any MP3 device in the hard-wired mode.
Again, if you're looking for a Bluetooth speaker with amazing performance, quality and affordability, you can't go wrong with the Sharkk.
