CONCLUSION

   Much like most things in the world the output power of a wireless portable speaker depends a lot on the size of its full range drivers (thus its overall size) so if its power you want then obviously the A28 was not designed for you. That's not to say that the TREK Flex A28 doesn't pack a punch since it does and quite a bit actually but simply put inferior to what its larger brothers the A74/35/34 models have to offer (on the bright side however it probably has a higher volume output compared to what you'd expect due to the size of all these solutions). In terms of build quality although just 572g heavy the A28 feels very sturdy. Mids and highs are quite good and so are its bass levels (for its size) but i have to admit that the also cylindrical BOOM by Ultimate Ears sounds a bit better overall and offers a far better 360 degree audio experience. Battery life is also quite good and although we were unable to hit 8 hours of continuous use we did surpass 6 hours (if only by a few minutes) with the volume turned almost all the way up. Some people may like the start/stop audio playback feature when the A28 connects and disconnects with a device so we can't really figure out if it's good or bad.

   The TREK Flex A28 wireless speaker by TDK currently retails for USD84.99 inside the USA (Amazon.com) and for 81Euros inside the EU (Amazon.co.uk) a price tag which is actually quite good for a rugged wireless portable speaker with very good volume levels, good audio quality and good battery life. It goes without saying that the A28 is not perfect and personally i have no idea as to why TDK didn't make a slightly larger cylindrical speaker to compete directly with the BOOM by Ultimate Ears (would be able to fit more or larger drivers inside and even a higher capacity rechargeable battery pack). Still this is a very solid product with good and very good scores across the board and that's why it gets our Golden Award.
