Because of the supplied set of silicone eartips, the JBL Tune Flex are some of the most adaptable true wireless earbuds that you can buy. You can use them either as open-ear headphones or as in-ear headphones, depending on which configuration you prefer. It is wonderful to have the alternative, even though the former won’t provide you with sound of the highest quality. Because of their water resistance rating of IPX4, these will be able to withstand light precipitation or perspiration; however, they will not be able to withstand being submerged in water for an extended period of time.
Because of this rating, you will be able to use them in a variety of various situations. Why would you want to purchase the JBL Tune Flex over a standard pair of in-ear headphones? There are going to be days when you would rather be aware of your surroundings and just want comfort, while there are going to be other days when you might want to cut the world out with music and opt for a secure fit instead of an open ear design.
[content-egg-block template=offers_logo hide=price]Having the option to choose between an open ear design and an in-ear design is something that is not offered by other options, so it is really useful to have that choice. These offer the advantages of both of the aforementioned options. Aside from the fact that they can morph, they are really good with a tonne of functions, a really cool design, and a very fair price tag. On the other hand, the battery life with ANC turned on leaves a lot to be desired.

Where to get JBL Tune Flex?
The recording was made in a crowded restaurant, and the earbuds were able to dampen the loud low-frequency rumbling just somewhat, but they did not cancel any frequencies. This performance shouldn’t come as a surprise given that the in-ear seal isn’t particularly good with either eartip. Instead of getting the Soundcore Liberty 4 NC, acquire the Soundcore Liberty 4 NC NC if noise cancellation is at all important to you. Both the Ambient Aware and TalkThru transparency modes from JBL operate as intended, although given the light in-canal seal, their use is not strictly required.
When you switch to the Ambient Aware mode, the sounds around you will have a more authentic sound, whereas the TalkThru option will allow conversations to be heard more clearly. The Tune Flex, much like all other JBL models, comes with an accompanying app that gives you control over a wide variety of features, including the amount of active noise cancellation (ANC), the balance of the equaliser, and the touch control gestures for the earbuds. Possibly the most striking feature is the equaliser, which gives you full creative control over the entire frequency graph.
The fact that these earphones have a tendency towards a more bass-heavy sound makes this adjusting option potentially handy. The highs are velvety and never reach any uncomfortable treble peaks; they are luscious and smooth. On the other hand, you won’t get as much sparkle or shine from these buds as you would from an earphone that has a higher level of brightness.
