BENCHMARKS

Design and connectivity

The Tronsmart Onyx Free Bluetooth earphones comes with a small carrying case to allow you to carry and charge your earphone. On the back of the case we have a USB Type-C connector that can be used with any conventional charger. If we use each of them in mono mode we can extend the hours of music even more.

  • Autonomy: Headphones 50 mAh – 7 hours / Box 500 mAh – 35 hours

The Tronsmart Onyx Free Bluetooth earphones fits into its case perfectly and is securely fastened, in the front area we have some leds that indicate if we are charging and the battery level of the case.

  • Charging time: 1 hour for the earphone / 2.5 hours for the case.

When the case is closed, a UV C + A sterilisation light is switched on, which cleans the surfaces of certain types of bacteria that do not tolerate this light intensively. In addition, thanks to the IPX7 protection we can clean them under the tap comfortably.

Controls

The Tronsmart Onyx Free earphone has touch control on the side, each earphone can be controlled individually, it is also possible to perform different functions with each earphone by light touch. It is possible to change the audio track, turn up the volume, answer calls or run the assistant on our Smartphone.

  • Assistants: Compatible with Google Assistant, Siri and Cortana.

Sound

We tested the Tronsmart Onyx Free Bluetooth earphone for several hours and found that the sound is quite good overall, this is a tightly priced product and that means we don’t have the maximum quality in bass or power. The sound is clear that in terms of medium volume and has an adequate definition, high volume that if they are somewhat short by their drivers of 6 mm, if we are not of listening to high music is acceptable.

  • Processor: Qualcomm QCC3020
  • Codecs: aptX / AAC / SBC

These headphones mount 6 mm drivers and Qualcomm QCC3020 processor with support for aptX, AAC and SBC codecs give the set a good quality. The microphones behave appropriately to pick up our voice. The noise cancellation system is more symbolic than effective, and the design of the earphone does not favour this aspect either.

  • Headphones: Drivers 6 mm / -42dB ± 1dB / 16Ω / 20 – 20K Hz
  • Bluetooth: 5.0 TWS / Mono or True Stereo

CONCLUSIONS AND BUY LINKS

Opinion

Once analyzed the Tronsmart Onyx Free Bluetooth earphones we can say that this is an attractive product for its price with which we have a sound quality more than acceptable for those who do not need very high volume. A earphone that allows us to use it in stereo or mono thanks to its Bluetooth 5.0 TWS function and includes microphones with basic noise cancellation system to give orders to our mobile assistants and answer calls. The UV sterilization system and the possibility of being able to wash them thanks to their IPX7 protection is appreciated in these times.

The Tronsmart Onyx Free Bluetooth earphones has a fairly clear sound with its 6 mm drivers although it is not ideal for those who need a lot of volume, the bass is acceptable and the aptX, AAC and SBC codecs perform their function correctly. The almost 7-hour runtime at medium volume allows us to use it for long sessions, the recharging box is convenient and the integrated USB Type-C connector allows for easy charging.

In general the Tronsmart Onyx Free earphones have correct sound at a good price, the cleaning system that is an interesting plus.
