What’s In The Box?
Build & Design
We’re looking at the TDK Life On Record TREK Micro in black, but that isn’t the only color available. It’s also available in iDevice-friendly white and a much flashier red option. Like it’s big brother, the TREK Micro doesn’t make a big deal out of showing how rug,ged it is. While it does indeed carry the same IP64 rating, you wouldn’t know it to look at — the simple plastic build and metal grill don’t seem flimsy, but you wouldn’t expect this to be as tough as it is at first glance.
Connectivity
Normally speakers this size offer the bare minimum in terms of connectivity options, but we were surprised to see that this isn’t the case here. Not only does the TREK Micro connect via Bluetooth, but NFC pairing is available. No matter which option you use, pairing your device is a simple process.

The 3.5 mm aux jack was expected, but we were thrilled to see a second 3.5 mm jack. This one is an output, allowing the TREK Micro to be used to add Bluetooth functionality to another speaker or even your home stereo system. Open up the waterproof flap on the side to find these ports as well as the on / off switch. This has another mode, “TWS” or True Wireless Stereo. This allows you to pair a second TREK Micro to use as a stereo pair.
The other buttons are minimal but functional. The Bluetooth button also doubles as the power button, and there are dedicated volume buttons, but to pause and resume playback or skip songs, you’ll need to pick up your device. A built in mic provides speakerphone, but again, you’ll need to answer and end calls on your phone.
Battery Life
TDK Life On Record states battery life as up to 6 hours. In our testing we got closer to 5, but considering this was heavy testing which included playing at near-max volumes for long periods, this is to be expected. Playback at moderate volumes should get you between 5 and 6 hours.
The TREK Micro includes a micro USB cable for charging but no AC adapter. In most cases, charging should only take around 2 hours, but if you’re charging the speaker by plu,gging it into a computer’s USB port, expect it to take a little bit longer.
Sound Quality
Speakers of this size can only do so much considering the small physical size of the speaker, so our expectations are always somewhat lower in this class, and our ratings are slightly adjusted accordingly. If judged by the same criteria as larger speakers, no speaker this size would ever get over a 5.
A word of advice before you use this speaker: make sure it’s laying flat on whatever surface it’s on. Keeping it vertically oriented is going to dramatically lower bass response.

Lows
While a speaker this small is limited by simple physics, we were surprised at how tight the low end sounded, unlike the normal loose, sloppy sounding mess present in most speakers this size. Bass guitars could disappear at times, but kick drums sounded tight and focused.
Mids
The lower mids are (relatively) thick sounding, and while some mud is present, the amount of clarity in this range was fairly decent. The high mids are rolled off a bit, which is a smart choice as it avoids harshness.
Highs
For the most part the highs are okay, but some cymbals were tinny sounding and frequencies became piercing on a few occasions. This is par for the course in speakers this size, however.

Stereo is non-existent (not surprising given the size) but as mentioned earlier, the TREK Micro can be paired with another model for actual stereo sound.
Conclusion
While the TDK Life On Record TREK Micro is slightly pricier than other speakers of its type, it’s also substantially tougher. Whether or not it’s a good buy comes down to a few issues, the first of which is how important that IP64 rating is. The second issue, which applies to all speakers this size, is whether portability is more important than sound quality. If it is, the TREK Micro is certainly a contender among speakers in its class.
