Design
Like other products from Jays I’ve tried, the m-Seven share a similar solid build quality, sleek design and smooth finish. The earpieces are made all of plastic, but look of good quality and seem durable enough with a matte color finish. For wireless use they are rated IPX5 and sweatproof suiting the more active use.
Fit is great too on the m-Seven. Without a doubt one of the most comfortable earphones among in-ear sets, regardless the wired or wireless options. While these are not small as more micro-sized IEMs, the shape is super ergonomic sitting almost flawlessly on the ear with good angle towards the ear canal. The nozzle itself may look short but the inner part of the shells gives proper length and with the long flanged tips the seal is instant. Isolation is very good as well, there are no vents and manage to block a good amount of noise. A good option for more crowded areas.
The charging storage case build quality is nice as well; also IPX5 rated and has a thin rubber-like coating. It has the modern Type-C USB port and is compact and lightweight enough unlike larger metal cases on other true-wireless sets I’ve tried. There is a small button on the back of the case that lights the small LED lights at the front to indicate the current case battery level.
The m-Seven integrate touch controls on both sides. The usual playback functions for play and track skipping, phone calls, and also volume control and voice assistance with the corresponding apps. While it is not possible to manually power off the earphones, they will still turn off after a few minutes of being paused. However, they cannot be turned on without putting them back to the case, so need to take the case along everywhere.
Battery and Wireless performance
Battery time is excellent here. Nowadays the lowest records for True wireless set are about 3~4, and newer models manage to double that time. The m-Seven is even higher and among the few models that reach the 9~10 hours from a single charge.
Bluetooth version is the newer 5.0, a now more standard on true-wireless in-ear sets than portable headphones that still keep the 4.2v. The pairing is as usual very simple and once added to the paired devices list the future connections should be quick. The wireless connectivity is decent but not best. No interference or noise on the audio signal even on crowded areas, but the BT antenna on the earphones seems to be too sensitive; if there is something too close blocking the playing source then the transmission may become very unstable and in occasions the earphones will turn off. That aside, the wireless range is decent. Supported BT codecs are not listed, but seem to very be limited to only SBC and AAC, so despite the 5.0v BT chip there is not even AptX.
Sound
The sound is on the m-Seven is not difficult to describe. It is still a true-wireless set, so as much as freedom from wires it may get, the limitations of such wireless type are present nonetheless. Usually soundstage reach and imaging quality are mostly affected; not a major flaw considering the comfort of complete portability.
The m-Seven themselves have a dark sound presentation with strong emphasis on the low-end and smooth laid-back midrange and treble. Certainly it has the ‘fun’ factor with a full and thick texture, a bit more musical and very forgiving. The bass is strongly enhanced, always forward when it is on the track but not crazy overwhelming when not called for. In quantities, it is fairly well leveled from sub to upper bass, though expectedly limited in its extension and sheer rumble, and the main low-end focus is still on the mid-bass area. Speed is about average, not best suited for fast and too complex genres, and accuracy is not a key feature, but it is controlled for a bass oriented wireless set.
The powerful and dominating bass does blend into the whole midrange sounding very warm. It is more present on the lower mids, being thick and dense, missing in articulation and clarity, whereas upper mids though still affected sound cleaner and more precise. Whole midrange is more laid-back and more distant next to the dominant bass. The thicker and very smooth texture presents lack of air and separation between instruments. Vocals can sound more forward; especially female singers gain more presence over male that sound more muffled due the bass power. On more vocals oriented music where there is less bass, then vocals sound particularly nicer – still a bit dry but with good texture.
Highs are even more laid-back, very smooth and forgiving. This follows the dark signature with a more limited upper extension and early roll-off on the upper-treble. Even on more aggressive tracks there is not enough sparkle and bite on upper instruments, and clarity and detail are not the focus of the m-Seven either. Clearly better suited for a relaxed, casual listening or for the active use where precision and imaging are less needed.
VS Zolo Liberty+ ($100~150)
Build quality is good on both but the Jays are still better. They also have a better finish and boost almost perfect ergonomics and higher isolation. Battery time is below to average on the Liberty+ while m-Seven rank among the best.
In sound matters, the Liberty+ present a more lively v-shaped sound with a more even, balanced sub to mid-bass response. Not as warm as the m-Seven and so the midrange is cleaner, less thick but similarly in distant. Treble is much brighter on the Liberty+ next to the dark and smooth m-Seven. Detail is more upfront on Liberty+ and a bit less forgiving. m-Seven have a little more depth while the Liberty+ more width, but both about average, decent for these kind of wireless earphones.
