While all songs mostly had the same steep v-shape, a few examples worth calling out were bass-heavy classics like Rick James’ Super Freak and the treble-rich Jackson 5’s ABC that truly exemplified the rich treble and chunky bass. Thankfully, there wasn’t any drop out or delay in the audio during our testing, which can be a problem with wireless models, so that stability is a huge boon for the Beats Flex. What we found was that the sound quality was actually relatively clear for a pair of in-ear drivers, however they don’t have a very large soundstage to the audio. In our two weeks with the headphones we listened to a bunch of songs on Amazon Prime Music and Spotify, and have a good idea of what you can expect in terms of sound quality. What we heard is pretty much what you’d expect – a deep v-shaped sound that accentuates the highs and lows of the audio spectrum at the expense of the mids.
On a positive note, the Beats Flex does come with a few different eartips – including some large and double-flange tips – that can help make finding the perfect fit a little easier.Īfter trying a few combinations of eartips we eventually landed on a decent seal and were finally able to test out the Beats Flex’s audio quality.
In fact, so far, the biggest fault of the Beats Flex’s design is that they don’t come with wing tips to secure them in your ear – without them, getting that perfect seal can be finicky and can come undone easily. The W1 Chip is less advanced than the H1 but it still gets the job done, and the semi-wireless form factor is manageable if a little unwieldy. Surprisingly, though, we didn’t find any of that to be a deal-breaker.

Besides hands-free Siri, the more expensive H1 Chip supports Bluetooth 5 versus the W1’s Bluetooth 4.2, which means you’ll get a slightly longer battery life with the H1 Chip, too.

The difference between the Beats Flex and more expensive Apple wireless earbuds like the AirPods Pro is that the latter uses the newer H1 Wireless Chip that enables hands-free Siri while the former uses the older W1 Chip. According to Beats, the headphones have a 12-hour battery life and fast charging that can provide an hour-and-a-half of playback off a 10-minute charge. Speaking of, charging is done through a USB-C port on the left side of the earbuds near the volume controls. Not only is that handy, but it can save you a ton of battery life, too.
What about a play/pause button? Well, you can use the multi-feature button, but the Beats Flex are also equipped with a sensor that will automatically pause the music when you take them off, and resume the music when you put them back on. The second is that the wire between the two buds can provide a home to in-line volume controls, a multi-feature button and a bigger battery, allowing the headphones to last longer between charges. That said, the cable isn’t without its advantages: first and foremost is the fact that they’re harder to lose than fully wireless earbuds. It’s a bit cumbersome having such a long cord wrap around your neck and, admittedly, having the two earbuds connected via a cable isn’t exactly what we’d consider the ideal solution in 2020. The earbuds themselves are actually fairly light (18.6g), but the cord that runs between them is about 32 inches and wraps around the back of your neck. Both are wireless (but not truly wireless like the Powerbeats Pro or Apple AirPods) and look identical. We’ll soon see a few examples.īut for any discontinuous function at x = a, f( x) would always be non differentiable at x = a since no unique tangent could be drawn to f( x) at x = a.Although Beats hasn’t said it to us directly, the Beats Flex seems to be a direct sequel to the older BeatsX Headphones that it released in 2016. Graphically, this means that the graph does not pass through x = a ‘smoothly’, there is a sharp turn at x = a.įor a discontinuous function f( x) at x = a we can define LHD and RHD separately. – If at a particular point x = a, the LHD and RHD have non-equal values or one (or both) of them does not exist, we say that f( x) is non differentiable at x = a. The derivative at x = a is denoted by f '(a) Let us now put the discussions we have done above in concrete mathematical form.Ĭonsider the curve \(f\left( x \right)
