The JBL Staying power Height II earphones, with an IPX7 ranking, are one of the crucial few, and given their $99.95 worth, general robust construct, and forged audio high quality, they are additionally one of the crucial very best values for someone in the hunt for cable-free, gym-friendly in-ears. Should you’re on the lookout for correct audio, those bass-forward earphones most certainly are not for you, however in the event you like the speculation of a few added bass, the Staying power Height II’s safe, water-proof have compatibility, and easy-to-operate controls lead them to a sensible choice for a fairly reasonably priced worth.


To be had in black, blue, or white fashions, the Staying power Height II earphones have a hook design that latches excessive of your ear for larger have compatibility safety. There are 3 pairs of silicone eartips incorporated, in small, medium, and massive sizes. I discovered the have compatibility to be rather safe—the over-ear hooks in point of fact lend a hand. Then again, in the event you put on glasses like I do, chunkier frames may compete for house in the back of your ear with the hooks.

An IPX7 ranking method the headphones can resist being submerged as much as a meter—and whilst Bluetooth sign doesn’t do neatly underwater, the purpose is you must be capable of put on those in heavy rain, and wash them off underneath a tap with out factor. The ranking doesn’t lengthen to the charging case, on the other hand, so bear in mind of rainy earpieces.

The touch-sensitive panels on each earpieces be offering easy-to-operate controls. A unmarried faucet at the left ear skips ahead a monitor, whilst a double monitor navigates again a monitor. A unmarried faucet at the proper ear performs or pauses audio, and a double faucet summons your tool’s voice assistant. A unmarried faucet on both ear will finish or solution an incoming name, and upward or downward swipes at the proper ear’s panel will modify the quantity. All of those had been smooth to function, although we discovered the quantity swipes to be rather less responsive—or a minimum of, more straightforward to misfire with. A couple of occasions, we attempted to decrease the quantity and as a substitute paused playback, however not one of the misfires led to anything else extra tense than that, and typically talking, the faucets paintings neatly and are smooth to keep in mind.

The charging case is essentially cumbersome—the earpieces are huge because of the hooks. The case has a troublesome, slippery contour, a flip-top lid, and a USB-C port on its rear panel for connecting the incorporated USB-C-to-USB-A charging cable. A standing LED at the entrance means that you can know the way a lot battery existence is left within the case.

What’s lacking? An app with EQ controls would had been a plus, however at this fairly low worth, it isn’t a deal breaker.


On tracks with intense sub-bass content material, like The Knife’s “Silent Shout,” the earphones ship a palpable thump. At peak, unwise quantity ranges, the bass doesn’t distort, and at extra reasonable ranges, the low-frequency reaction remains to be tough, however additionally it is balanced out with sculpting within the highs.

Invoice Callahan’s “Drover,” a monitor with a long way much less deep bass within the combine, provides us a greater sense of the Staying power Height II’s basic sound signature. The drums in this monitor sound thunderous—that is an exaggerated bass reaction for sure. Callahan’s baritone vocals get an additional serving to of low-mid richness, as neatly. However JBL does a laudable process of a minimum of counterbalancing the boosting with crisp high-mid and high-frequency presence—the guitar strums and higher-register percussive hits are vibrant and likewise driven ahead within the combine. What we finally end up with is a scooped sound signature, with loads of low-end, loads of treble, and slightly bit much less within the center. It will not be correct, however it is going to enchantment to various listeners, particularly those that are motivated via further bass reaction whilst exercising.

On Jay-Z and Kanye West’s “No Church within the Wild,” the kick drum loop receives sufficient high-mid presence for its assault to retain its punchiness, however the lows are way more boosted, and so the loop sounds heavier than it generally does. The vinyl crackle and hiss that’s typically relegated to background standing takes a step ahead, too, indicating that the highs are certainly boosted right here. The sub-bass synth hits that punctuate the beat are delivered with spectacular depth—we’ve heard heavier sub-bass intensity shape some in-ears, however JBL manages to ship really extensive, exaggerated thump with out ruining the full steadiness of the combo. The vocals in this monitor are delivered with crisp readability and no longer a lot added sibilance.

Orchestral tracks, like the hole scene from John Adams’ The Gospel Consistent with the Different Mary, are delivered with a heavy bass-forward lean. It could sound terrible had been it no longer for the numerous high-frequency sculpting in play, as neatly.
