Setup, Design & Observations
The Razer leviathan comes precharged, but would normally be best to fully charge before use anyway. It is worth noting that you should only use the included power adaptor for the Leviathan as others may not fit the specifications needed to correctly charge or may cause damage. From empty, it is stated that the Leviathan Mini takes around 4 hours to charge to max and has a life span of around 10 hours. Unlike the Creative ROAR, which contains a 6000mAH battery, the Razer Leviathan has a relatively meagre 2600mAH, though considering it misses out on an additional subwoofer, the Leviathan Mini will undoubtedly require less power. Over the course of a day playing music mostly at maximum, with pauses/stops then use in comboplay, then using to make several calls, I wasn't able to drain the battery past the amber light on the power switch, considering this is over a period of time close to 10 hours, I would expect the life span to be close to the 10 hours stated.
Visually, the Leviathan Mini looks great and the button layout is easy to understand. As sleek as it looks, it feels great quality too, the buttons feel sturdy and good quality. The supporting accessories included are as you would expect power and required cables, though the inclusion of a carry case is most welcome. The multifunction button can be used to play/pause with a single press as well as double tap for next/triple tap for back commands. For use with comboplay, you will need to hold the button down for a few seconds while connected to a device via Bluetooth (not via jack), then turn on the other Leviathan Mini and again hold the MFB. The MFB can also be used to answer/mute and end calls by a single press, single press, hold respectively.
There are a number of features that would have been nice to see on the Leviathan Mini, such as a mini SD card reader for internal playback. Though considering this would increase the size/weight, it seems Razer have passed on this to preserve its portability.
On powering on the speaker you are greeted with a sweeping tone that shows off a surprisingly beefy bass. As hinted, the bass performance was impressively creamy without being overbearing. The mids and highs produced are nice and clear without distortion, even at its highest volume that is easily capable of filling a room with sound. Its overall precision and tonal separation across the board is a touch less refined than than what is observed in the Roar, though this is expected considering the size and technical differences. So, this level of discernment isn't something that can be outright justified considering the awesome performance and presence in such a small form.
After pairing up the two speakers together, I noticed that if there is a drop in streaming by your phone, there is a knock on effect where the secondary Leviathan Mini may drop out after the connection is re-established. During continuous play, this may mean that there were inconsistencies during overall playback between the two speakers. So if you are using a streaming audio app (E.G. Spotify, Soundcloud etc) you may not experience the most consistent performance. Though the audio was never out of sync, that is certainly a positive. During a more stable playback using media stored on my phone, the comboplay gave an impressive boost in volume and presence that was awesome enough to shock my brother once he realised that the music was being played through these tiny speakers on my side. There are two modes that you can choose from while you have two speakers in comboplay, by default it is in 'mono mode' where audio will be played via both speakers simultaneously, or you can select stereo mode by pressing the '-' and '+' buttons together for a few seconds till you hear a beep. The primary speaker you are paired with will then act as the left side speaker. By repeating the process you will flip the L&R channels, and again for the third time to revert back to mono mode.
During my calls, the microphone was picked up as loud, and sounded best from a few metres away, too close (within 1m) it sounded too loud though remained clear. Some background noise was picked up, but it done a great job of focusing the voice. A background siren was picked up rather too loud and clear and conversation was near impossible until the vehicle was out of earshot. Generally speaking though, microphone is usable and perfectly adequate for decent phone calls.
