6D Shock Stereo True 5.0 Wireless Earphones (JR-T04S)
The best wireless earbuds deliver more than just freedom from wires. You should expect a comfortable fit, long battery life and crisp audio quality, whether you’re listening to music, enjoying a podcast or watching Netflix.
If you’re willing to splurge, you can get active noise canceling wireless earbuds, which can help drown out the racket around you. More premium buds also offer an ambient listening mode so you can hear the world around you without taking out the earbuds.
Available in white, the SJR-T04S have a glossy exterior and touch-sensitive control surfaces on the outer panels. Like the Apple AirPods, they have a stem that hangs down from your ear, but unlike the AirPods, they are proper earphones that seal off the ear canal completely. They are also rated IPX5, meaning they can withstand water splashes from any direction, but shouldn’t be submerged.
The on-ear controls divide tasks between the two earpieces, with the right ear controlling playback, call management, and track forward; and the left ear controlling track backward and summoning your mobile device’s voice assistant. All of these actions are handled with various taps or holds for a few seconds. There are also some phone-specific controls that can be utilized when on a call, such as a double-tap putting the current call on hold to answer an incoming call.
The best part of this TWS is it’s 6D HIFI sound quality with deep bass and crystal crisp treble thanks to a 13mm stereo speaker. It comes with a built-in high-quality noise reduction technology chip, letting you appreciate all the details of your music. And at the same time, both earbuds can be switched.
The flip-top charging case has a white matte surface, with one status LED on the front face. The included micro USB charging cable connects to the micro USB port on the bottom panel. You also get five pairs of silicone ear tips. The earpieces don’t utilize any earfins in addition to the tips, but the fit is quite secure. Both the earbuds and the charging box battery status can be reflected on your mobile phone.
JR-T04S battery life is estimated to be roughly 3.5 hours, with a whopping 48 extra hours in the charging case.
Internally, 13mm drivers deliver a frequency range of 20Hz-20kHz. On tracks with intense sub-bass content, like Ellie Goulding’s “Outside ft,” the earphones have strong low-frequency depth. At the top, unwise listening levels, the bass doesn’t distort, and at more reasonable volumes, the low-frequency response is still quite palpable and decently matched with the highs.
“Two Steps Behind” by Def Leppard, a track with far less deep bass in the mix, gives us a better sense of the JR-T04S general sound signature. The drums on this track get some added bass boosting, pushing them into a near-thunderous territory but stopping just shy of it. Def Leppard’s baritone vocals get a nice, rich low-mid presence, matched with a solid definition in the high-mids. The acoustic guitar strums and the higher-register percussive hits are bright and crisp, and even the tape hiss takes a slight step forward in the mix. In other words, this is a sculpted, boosted, but a balanced sound signature.
On Chris Media’s “What are words,” the kick drum loop receives plenty of high-mid presence, allowing its attack to maintain its punchy edge, while the vinyl crackle and hiss that are typically in the background get pushed forward. The sub-bass synth hits that punctuate the beat are delivered with serious depth—we’ve certainly heard deeper bass boosting on this track, but JR-T04S definitely doesn’t shy away from the lows. Luckily, the deep lows are balanced with crisp high-mids and highs. The vocal performances are delivered with excellent clarity, but perhaps a bit of added sibilant.
