Product Description

Rock Hard, Rock Steady

Sometimes the life of the party is the person who brings the tunes. The Rock steady XS Bluetooth speaker was designed with this person in mind. Bring portable, big sound with you to your get-togethers and kick-backs. Share control of the speaker with a friend, as the Rock steady allows 2 devices to be connected simultaneously. This allows friends and partygoers to swap playing tunes for the group from their own devices. Anyone can play DJ for a few songs without having to hassle with re-pairing the speaker. Made with a rugged aluminum case, the speaker can safely be brought out to the wilds of the earth and banged around inside of a bag with little care for damaging the chassis. Whether you’re rocking out and head banging at the office, thumping tracks in your room, at a party, or conducting an impromptu open-air drunken karaoke session, this speaker can handle it and then some.

Killer Concepts

Killer Concepts was founded in 2011 by best friends Jeff Leitman and Rick Cao in sunny Southern California. Frustrated with high priced, low performing technology products, they decided to do something about it. The offerings in the market for ‘Stereo Bluetooth Portable Speakers’ weren’t loud enough to hear over the surf at the beach or noises at the park when they played basketball; and battery life was never as long as they needed it to be. Jeff and Rick set their sites on designing the worlds best unit, loud, clear, long lasting battery, and at a fair price. The Rocksteady XS was born. And that is just the start, with 3 new products on the designing table, Killer Concepts will continue to innovate and lead the market, offering the best featured and performing products in a number of categories, always at fair prices. Killer Concepts has a focus on people’s needs. The Rocksteady XS was created to meet the demand for a wireless Bluetooth speaker that is loud, light weight, portable, and has a long battery life. We listened to the market then and we’re still listening now. The Rocksteady XS is just the beginning, more convenient and useful products are to come.

My first RocksteadyXS unit was received in America a few days before moving to China, and quickly found to be defective. Jeff from Killer Concepts personally helped resolve the issue, getting a replacement sent to me from Shenzhen to Chengdu via courier service. I am very pleased with my working unit.

Sound quality: I believe the Rocksteady offers the best sound quality of its class. Obviously, bigger speakers are going to offer more impressive sound- speaker diameter is a pretty straightforward concept- but for something this portable, you'd be hard-pressed to find a sweeter sounding device. I've compared it to similarly sized speakers; the Jambox (pffft), Logitech's Mobile Boombox, and a couple boutique bluetooth players- and preferred it over all of them. One of the most impressive features of the Rocksteady is its ability to play at maximum volume without any cracks or distortion. You can easily fill an average sized room with its sound.

Bluetooth: Syncs very quickly. Once your laptop or phone/whatever has recognized the Rocksteady, you can sync it from then on by pressing the Mode button once. It takes 2-3 seconds.
Unfortunately, the wireless range is very limited. I could not bring my Rocksteady more than 5-6 feet away from my laptop without its connection getting choppy. This does not bother me, as I enjoy bluetooth for allowing me to not use cords and position the speaker more freely, but should be noted.

Aesthetic & durability: I'd feel safe tossing this thing in my backpack and using it with my phone as a boombox. In fact, I do this regularly. And the thing looks slick. I'm a sucker for minimalist designs and matte black finishes. The easy access to the replaceable battery is a boon to its design.

I have a Bose SoundDock and love it but wanted something smaller that I could bring to work with me everyday. At first I thought I would buy a cheap $30-40 speaker because I already have the Bose but I also looked at the speakers near $100 just for the heck of it. I stumbled across the RockSteady XS and though it is fairly new and doesn't have a lot of reviews, I decided to check it out and figured I could always return it if it didn't work out.

Some big things that made me decide to get it was finding out that the battery it uses is replaceable and costs just a couple of $$. The battery is the BL-5C battery used in Nokia phones. Ebay has some extended capacity versions that are 2450 mah, but the Rocksteady uses the 1050mah version. Both should work fine and can be charged quickly.

Along with the user replaceable battery being a selling point, the small size and the side firing dual speakers along with the vent on the top sounded like it would allow for a full and distortion-free sound. That is exactly what this speaker delivers. The bass hits harder than you would expect from a small speaker and it is plenty loud without sounding distorted or like the speaker is going to blow, even when playing very loud bass heavy dubstep.

The Bose is much louder and bass heavy, but I didn't expect this much cheaper speaker to be anywhere near the quality of the Bose. Even though this speaker costs 4 times less than the Bose (including the cost of the Bose extra battery), the RockSteady does stand up to the competition. It sounds great and is much more portable. I highly recommend this speaker to people who already have a high quality bluetooth speaker but who want something more portable that still has good sound like you are used to.

I purchased the RockSteady XS speaker in Dec and use it everyday. The sound is incredible. It is very loud, very clear and has a good base sound to it. I found it very easy to pair with an iPhone and I like the idea of replaceable batteries, even though I haven't used that yet. For under $100, this is a great value.

The problem I have with most bluetooth speakers of this size is that the max volume, while good in small quiet rooms, tends to not be high enough for situations with background noise- such as in the bathroom when showering, or in a car. The XS has good sound quality for its size, and the volume is top in its class. The build quality is rock solid- its all extruded aluminum. The battery is replaceable and uses a standard Nokia BL-5C battery ($5). Battery life is good as well.
The only criticism I have is maybe with its aesthetics. Its a bit industrial/unrefined- especially the row of buttons on the front with the huge logo above. Also if you consider yourself an audiophile, I doubt any of these small bluetooth speakers will make you happy.
The price drop to the $80 range makes it easily best in class.

After scrutinizing the the myriad of choices available on this new technology (bluetooth speakers), and auditioning several models from various manufacturers, and different price ranges, I came across this model ROCKSTEADY XS from KILLER CONCEPTS, LLC.
WHAT ME LIKE AND MAKES ME HAPPY TOO MUCH! : For the sake of brevity I'll go straight to the great attributes
of this Bluetooth speaker,
1- Housing is well machined, which preserves the integrity of the "innards", not cheap, you can feel the heft.
2-Battery longevity is 10+ hours and, is accessible from bottom trap door. Also, is replaceable from AMAZON.
3-PERFORMANCE! This puts (IMHO) many of the other high price and name brand competition, to shame!
I can't believe how high this "mutha" cranks without distorting! Bass, treble, fidelity, all intact.
4-Price: $54+ free shipping! big bargain from AMAZON!
