Design & Durability
The design is attractive and wouldn't look out of place left on the side. The S7BT is pretty hefty at 410g of aluminium and overall feels solid. The only areas that look like they could receive some damage would be the stand or the plastic top. It is difficult to tell how the inner workings will react to a drop or fall though one thing is for sure, you do not want to drop this item on your foot, it will hurt. Build quality is hard to gauge considering it is mostly solid aluminum but I would suggest caution, not only because it may break from a fall, but it could potentially damage your floor and considering this is a vibrating unit, it may vibrate itself off whatever surface you have placed it on. The rubber padding on the base is fairly squishy and allows a semi adhesion to a smooth surface and works well, but on the wrong kind of surface it may not hold well, and on a particularly springy surface, it may encourage the S7BT to vibro creep. The buttons seem to be a little stiff but work well. The Bluetooth setup was very easy using various android phones, once connected it worked! Simple and had no issue staying connected through walls at a distance of 6-7m though moving out into the garden was a little bit of a stretch.

Music
Listening to music was fun and impressive. Firstly, audio quality dramatically changed depending on the type of surface the device is mounted on, so I will try and give some impressions, though it may vary for different situations and you will need to find what works best for you.

- Glass: The bass disappeared and had the tone had fairly high pitched ring to it.
- A chipboard chest of drawers: Lots of boomy bass with little to no mids and clear treble.
- Laminate floor: Little bass, good mids, little to no treble.
- A wooden table on carpet: There was a lot of vibro/bounce causing the speaker vibrate/slide.

After a fair bit of experimentation I came to the conclusion that there is an 'ideal' surface, one that isn't too hard nor too bouncy. The best location I could find was a sturdy wooden desk with a firm floor/lite carpet. The clear space underneath allowed excellent bass reproduction while the more solid nature of the surface allowed for clear highs and mid tones which is genuinely impressive. The volume is a lot more than one would expect too, easily able to fill a small room with reasonably loud, good quality audio. This also may lead to the downfall of a product like this, that is, the sound was single point, I.E. monaural and it is very easy to locate the direction of the music and can slightly be distracting just simply realising the direction of the sound. It would be interesting to discover if this device can link up to two or many of the S7BT vibro speakers for stereo/ awesome. Another warning would be to consider what kind of music you are playing, it turns out that very bassy music when played loud can literally cause the device to jump despite how well the sticky padding tries to keeps it grounded.

Calls

Phone calls were easy to make and the mic was clear while the S7BT transmitted voice loud and clear. Definitely better than any phone built in loudspeaker. While it couldn't be tested with a games console, if it performs similar to a phone call or better, then it could really make a great addition to your gaming peripherals should you enjoy a more open game chat without using a headset.
