In comparison to the Tune 130NC, they fit snugly and have a stem design that feels more secure in the ear. Both the case and the buds are made of quality plastic. The earpieces don’t appear to be particularly high-end, but they also don’t appear to be overly cheap. This is in part because of the huge, noticeable JBL logos on both earpieces and charging case as well as their rough surfaces.

When you put the earpieces in your ears or in the charging case, the touch-sensitive control panels on the outside of each earpiece are quickly activated. There are notification LEDs inside the case, and the casing is powered via a USB Type-C connector on the back.

To access a variety of features, the buds must be connected to the JBL Headphones app, which is available for both iOS and Android. You can access the EQ and alternate between ANC and ambient sound modes via the app. There is a tonne of presets for the EQ. The app also offers the user alternatives like video mode, audio mode, and standard mode, each of which prioritizes a different aspect of connection stability over another (which cuts down on latency).

Two touches on the left ear activate TalkThru mode, which lowers the music volume and allows you to hear your surroundings. Double and triple taps on the right ear are used to regulate the forward and backward track, respectively. Each earpiece can be double-tapped to answer or end calls. Press and hold either earpiece to start the voice assistant on your device. These controls are now set as defaults, however, they can be modified using the JBL Headphones app.

The Tune Flex offers access to basic Bluetooth codecs like AAC and SBC. According to the company’s marketing materials, the sound stage in our tests was balanced with a light emphasis on the bass. The bulk of customers should be satisfied because Indian audiences appreciate audio products with a strong bass level. The drivers have a little depth for their size, but the sound stage is balanced. Static noise, which is frequently present with TWS devices, wasn’t anything we noticed. The size of the touch-sensitive portions is appropriate, and the touch instructions function as intended.

In most usage circumstances, we observed that the Active Noise Cancellation performance was only average. It is fairly soft to start, as one would anticipate from a pair of buds costing below INR 8,000. They could reduce minor fan or air conditioner rumbles, but in a crowded area, they couldn’t accomplish much. With volume levels at 50%, the buds’ battery life was around 7 hours on a single charge and 30 hours overall with the ANC off; with the ANC on, the buds only lasted 6 hours. Now, these values closely match the ones that were advertised. It takes around 2 hours to fully charge both the buds and the case.
