The claims made by manufacturers of Bluetooth speakers about battery life are normally measured at very low levels of volume which rarely correspond to real-life usage and hence this review of Nimmu Technologies Bluetooth 5.3 speaker focuses on the battery life claim of 36 hours under realistic moderate volume usage throughout a couple of days of normal usage both indoors and outdoors and tests of true wireless stereo functionality to determine if there is any improvement in sound stage when connecting a second unit with the first one. The focus of this review is on real-life impressions as opposed to just an initial first-day impression.
But Is There Any Such Thing As 36 Hours Of Battery Life?
First things first – the most impressive feature of this speaker is the 36 hours of battery life! In a market saturated with cheap devices that can last about five-six hours, it is a rather bold statement to make. And while the volume level definitely plays a key role in the battery consumption, the efficiency of Bluetooth 5.3 allows this particular model to beat its direct competition easily. No, you will not have to drag your charging cord with you on the weekend away from home.
Sound Quality and Portability
It goes without saying that this particular model will not be able to handle a neighborhood block party. But for individual listening – working at your desk, doing some cooking or relaxing in the hotel – the audio quality will pleasantly surprise you by being better than expected: you will not feel any powerful sub-bass, yet the low end will be balanced enough to avoid that tinny and harsh high end characteristic for budget speakers.
However, the most impressive thing about the device in question is definitely not the quality of the audio, but the ability to pair two of those units in TWS mode: this way, you will be able to transform your mono audio into something close to stereo experience.
Who Is It For?
This device will be perfect for everyone who needs an affordable, compact and reliable speaker for travelling, studies, or for a regular listening session. It is lightweight, rugged enough to throw it into your backpack, and the microphone quality is quite good for quick call handling.
Who Needs To Avoid It?
It is absolutely not for people who are interested in sub-bass experience and/or want a device suitable for large spaces.

Our Verdict
The battery life of Nimmu Technologies Bluetooth 5.3 Speaker almost matches its claims when using realistic moderate volume and lasts through several days of listening sessions without requiring recharging. The true wireless stereo works well and creates a noticeably wide sound stage without any lags or synchronization problems between two units. The bass is good considering the size of the speaker although at higher volumes, it is not expected to beat a setup with subwoofer. The Bluetooth 5.3 works well and does not drop out in a typical room. Overall, this speaker is highly recommended for those who are seeking for genuine battery life and functionality. That is what makes it a worthwhile buy.
