JAYS t-Seven True Wireless Review

A while ago the Swedish manufacturer JAYS released the f-Five, an affordable true wireless earbud that had most of what you’d need out of a product like this. Some of the frequency response was lacking, but a good bass and responsive controls made them worth their generous price. The t-Seven is the latest in this series of true wireless earbuds. They may look similar in design, but the t-Seven hikes the price up a bit more to $149.99. What has JAYS changed in their core design that represents the raised price?

Look and Feel

As I previously mentioned, the t-Seven resembles one of its former models, the f-Five. They both take the Airpod inspired oval-shaped housing with a long stem. However, the t-Seven has a much shorter stem, which is a design I prefer. I haven’t been a fan of stemmed earbuds in general, but the shorter ones do provide the proper security needed with true wireless. Nothing else about the style really grabs you, but the white logo on the black surface looked nice to me. The aesthetic might not pop, but the fit is definitely there. I never felt like the size was any kind of distraction to the t-Seven’s level of comfortability. The fit was always consistently snug and secure.

Design and Functionality

The t-Seven supports a standard 6mm driver unit with an impedance of 32 Ohms. It’s one of those earbuds that just gets loud enough when cranking the volume up full blast. A more comfortable gain is always preferred, but the output of the earphone possesses enough volume to enjoy at its limit. One of the main advantages of true wireless is the many features that can be held inside.

Active noise canceling is introduced to this series, and it can be accessed like most of the t-Seven’s features through its touch-sensitive interface. I very much enjoyed the responsiveness of the last model, so I expected something similar here. The feedback of the controls makes a click sound like you’re pressing a button, which made for a gratifying user experience. The click is always responsive and quite sensitive even. With a short delay, the actions feel natural and ensure receptivity. 

JAYS charging


JAYS gives the t-Seven Bluetooth 5.0 support, with only access to an SBC CODEC. It features a range of up to 10 meters.

Battery Life

Off a single charge, the earphones should last about 5 hours, with the charging case adding up to 20 hours total. This is about the average battery life you’ll see with a Bluetooth earbud at this price, but there are still other models out there with longer playback time for less.

When it comes to true wireless, I’m only expecting the soundstage to accomplish a standard amount of separation and clarity. Width isn’t something you normally get a lot of in true wireless, but that makes hearing a good amount of it that much more special. The t-Seven is mostly centered, but some elements do show some width when panned to more extreme positions. Listening to some strings, the stage expands more noticeably than with more contemporary tracks. The imaging appears much bigger than on the f-Five, and is an immediately noticeable improvement. Tracks meant to feel grand, are portrayed accurately and with enough space to make an impression.

Low End

Bass frequencies have an immediate punch. The textures are crisp and the tonality is properly thick and booming. It’s an impactful response that gives the t-Seven a ton of energy, and perfect for bassheads too. Some lower frequencies can resonate to a rumbling effect, but the frequencies have enough separation to not bleed too much into the mids. An impactful low-end response. 


The timbre of the midrange doesn’t appear quite as full as the lows, but the high and low mids do have some present emphasis. The rest of the mids aren’t completely scooped out, but they’re definitely recessed and leave the low-mids to do most of the lifting. Vocals and instrumentals sound clear enough but don’t expect much more out of the resolution.


Treble was mostly very pleasant with a small amount of brightness. Next to the bass, the highs present the most amount of character to the timbre, providing a relaxed tonality with room for details. The texture here is most notable with wind instruments and bells, as they have a certain shine, but never approach that piercing territory. 


Overall I enjoyed listening to the JAYS t-Seven to a surprising amount. After the f-Five I wasn’t expecting anything outside of controls and call clarity, but JAYS steps it up in the sound department considerably. The lows will attract any basshead, and the rest of the sound signature will prove to be very enjoyable for most listeners. There are some improvements to be made in noise-canceling, but this is still an all-around solid product worth the price.
