JBL Live 300TWS Review • Bluetooth in-ear headphones

JBL Live 300TWS

Among the wireless headphones that have become fashionable lately, there are some that work well… With the Live 300TWS, JBL delivers usability and performance.

Wireless audio transmission may be taboo for friends of high-fidelity, but there are times when wireless is almost essential. One such field of application is sports headphones, which are called to operate under special conditions to offer their music – and not only – services.

The Live 300TWS seem to be very well thought out in terms of customization, judging by their application to me. JBL provides silicone adapters in three sizes, both for the ear canal and for stabilizing the earpiece at the earlobe.

The Live 300TWS are controlled by gestures by touching their sensitive surfaces bearing the JBL logo. The user can adjust the playback level, pause or command the next or previous track in the playlist without having to take the smartphone out of the pocket (or strap). Gestures are defined through the Android application, JBL Headphones provided free of charge by the manufacturer.

In order for the user to be able to hear the noises of the environment, there is the Ambient Aware function, while Talk Thru emphasizes the voice and facilitates the conversation with the built-in microphone, without having to remove the headphones. Ambient Aware or Talk Thru is also set up through the JBL Headphones application, as well as their activation and deactivation.

On the road

The JBL headphones have a range of 6 hours, while the provided storage case that also functions as a power bank, offers an additional 14 hours of operation. These performances are by no means negligible. Suffice it to say that I have tried branded sports headphones in the past with a range of 30 minutes οντας Having solved the important issue of autonomy, we may be concerned about the next important issue which is nothing more than comfort. The JBL Live 300TWS can be worn for the entire time of their autonomy without tiring the user. You just wear them and forget about them. And in this area of ​​comfort, JBL is leaving light years behind some of its brand competitors.

Bluetooth 5.0 wireless technology, backed by the Live 300TWS, is an ally of JBL in achieving its “audio signature”, as it proudly points out. Bluetooth 5.0 is the latest version of this technology and contributes to the high energy autonomy of the Live 300TWS, as well as to their audio performance, with a maximum theoretical data transfer rate of 2Mbps, according to the specifications.

The JBL Live 300TWS has great sound, a sound no one expects from in-ear headphones. The low is full and dynamic, with no dominance in the middle area – given that the equalizer in the Headphones app is flat. The levels achieved are more than enough. The high range is descriptive and does not tire after long hours of listening, until the Live 300TWS battery is exhausted. The sound insulation achieved is satisfactory, everyone should consider if and how much they will use the Ambient Aware function for their safety.

The phone call, of course, interrupts the hearing. Its sound is stereo, with the interlocutor sounding better than ever. We can not know if our own voice sounds better, but our interlocutors did not face any problems and seemed to understand us fully and easily.

With the main advantages of comfort, long battery life and excellent sound, qualities that are not at all self-evident (nor common) for wireless Bluetooth headsets, the JBL Live 300TWS are a decisive move of their user towards its audio autonomy.
