Test: JBL Tune 120TWS – Powerful Wireless Sound

5 min

Review: The JBL Tune 120TWS's fine energetic bass-heavy sound and wireless freedom are quickly appreciated, but the ergonomics are not well thought out.

The Tune 120TWS is a new set of completely wireless in-ear headphones from well-known JBL, which is a tempting cheap alternative to other similar headphones on the market. Apple AirPods, Jabra Elite 65t, Libratone Track Air +, SonyWF-1000XM3 and Sennheiser Momentum True Wireless all cost over £ 1,000, with the JBL Tune 120TWS having a suggested retail price of £ 799 and already priced at just £ 699.

The Tune 120TWS plays with JBL's well-known Pure Bass sound, where the bass has been turned up, but still with a nice part-detailed treble. The support plays for 4 hours and comes with a charging case, which, according to the manufacturer, provides up to 12 hours extra.

We have had JBL Tune 120TWS for testing and here are our experiences.

The JBL Tune 120TWS is quite a nice st in-ear headphones. TWS, True Wireless Sound, gives a hint that no cables are needed – except when charging. They are larger than JBL's own pictures show and protrude further out of the clean, but fortunately not so far that it irritates and looks silly.

They are made of hard shiny plastic and look solid. Instead of touch input, they are equipped with physical buttons that need to be pressed quite hard. It requires holding the small headphones when they need to be operated if they are not to be permanently stuck in place.

The charging case is also made of hard plastic and is quite sturdy. It is bigger and not as well executed as the more expensive alternatives, but the quality is definitely approved. The two headphones are held in the case by two small magnets so that they do not fall out when the case opens.

In the shine are three basic ear tips: small, medium and large size. It should be possible for most people to find an appropriate size. However, getting the JBL 120TWS to get stuck is a bit of a challenge. They are only held by the small ear tips, where most other earphones are designed in a way so that their cabinets support in the rain and provide more support. We have found that the Tune 120TWS slides out too easily and often has to be pushed back, especially if you walk, run or the like. If they are to be stuck at all, they must be pressed in well and you quickly get hurt in the reel.

But pipes are different and maybe they fit better on others – it's always hard to conclude something about the fit of in-ear headphones. We have had several try them out where everyone had challenges with the fit. Therefore, we would clearly recommend that you try them before kb, so you know they sit properly.

In my tubes, the Tune 120TWS protrudes farther and can possibly no longer enter. Here is a comparison with the Jabra Elite Active 65t. Jabra on the left and JBL on the right.

Up to 16 hours of battery

According to the manufacturer, the JBL Tune 120TWS gives 4 hours of music on a charge, with the included charging case we are up for a total of 16 hours. That is pretty much what we have experienced, but we have experienced problems with the charging case that very quickly lose power. Even when the headphones are fully charged, the case still loses power. Whether the headphones are still charging, even if they are fully charged or where the power goes, we do not know. If the Tune 120TWS is charged on the table in the case, you can quickly use a battery-flat case, which is not at all optimal. However, it should be something JBL can reasonably easily solve with a software update.

Unfortunately, the charging case is only equipped with MicroUSB charging, where it could be nice to use the cable for the mobile phone that is already ready in the power adapter.

After 15 minutes in the charging case, JBL Tune plays 120TWS for about an hour.

Approved Pure Bass sound

The JBL Tune 120TWS are the most durable wireless in-ear headphones we've tested. It is definitely not something JBL does not hide and calls the sound "Pure Bass". If you like extra bass, then the Tune 120TWS is definitely for you.

They play especially well when listening to pop music, hip hop / rap and rock, but acoustic, blues and the like are not their strong side. Despite the heavy bass, 120TWS plays with surprisingly good clarity. The treble is detailed and the bumps, hi-hat and other brains sound really nice. There is a nice stereo perspective and transparency in the music.

For conversations, the JBL Tune 120TWS also works really well. Voices are clear and clear and the built-in microphones also give an approved sound.

The Tune 120TWS has built-in Google Assistant and Siri. Press the headset twice and the assistant will activate automatically, but you must be ready to get clean. The sound from the assistant is much louder than, for example, music.

JBL Tune 120TWS: Conclusion

For the price, the JBL Tune 120TWS is a pretty good wireless in-ear headphones. For less than 700 kr you get freedom of choice, good sound, rechargeable cases, nice design and solid build quality.

They are not perfect. Especially the fit causes problems and there is little challenge with the battery of the charging case, and the lack of protection against dust and water can worry. In contrast, there has been absolutely no problem with the Bluetooth connection between the two headphones and mobile phone.

Try them before you buy, and if you are lucky that they are seated properly, they are a really good buy.

JBL Tune 120TWS lands on 4 out of 6 stars.
