ACCESSORIES
In addition to the TWS buds, the following are included:
- USB type-C charging cable
- Pouch
- Charging case
The accessories are pretty decent fare for the $20ish USD entrance fee.
The charging case charges via a USB type-C cable, and operates via a plastic sliding cover. The JW1 earpieces are stored on the back and front respectively via a magnetic clasp, allowing it to even be held upside down against gravity!
The carrying case is quite unique for a TWS set, albeit it is on the larger side, with measurements of 91.6 mm x 55.6 mm x 28.6 mm. With the JW1 packed inside the case, the total weight is about 85 g, which is quite portable.
Taking out or putting the JW1 into the charging case will power it on or off automatically. Alternatively, pressing the touch button for 5 seconds will also switch it on or off.
As the plastic casing is potentially scratchable, the drawstring pouch is a nifty addition to store the JW1 and the case for protection.
BUILD/UTILITY
The JW1 is solidly fashioned from plastic, and I've no complaints on the build front. When ordering, one can opt between a black or a white version.
It is meant to be worn over-ear (with the earhook behind the ears), and is akin to a earbud, with the transducer placed outside the ear canal. This open-backed design thus provides an expansive soundstage and allows situational awareness, though on the flip-side, passive isolation is zero and some sound may leak out in quiet environments.
This open-backed concept makes the JW1 a useful tool for sports, outdoor activities, or even for exercising, though it may not be the best option for usage in a noisy place, and there is also some loss of sub-bass, which we will discuss later.
For my average sized ears (and as a spectacles user), the comfort is commendable. Each earpiece weighs in at 9.5 g, and it is not too noticeable once hooked on the ears. For the three weeks I've been putting the JW through its paces, I did not encounter any discomfort. The earhooks - though not adjustable - provide a very snug fit, and even when running or shaking the head, the JW1 is very secure with no droppages. However, those with bigger ears might potentially find the non-adjustable earhooks to be an issue.
Speaking about exercise, the JW1 is advertised to be water resistant (though I could not find any info on IPX rating). I've used it for a few weeks with gym work or even jogging in light rain, and it has held up!
FUNCTION
The touch button is located at the end of the JW1's earhook. The buttons work as per below:
The touch button is quite small and requires one to place a finger behind the ears to manipulate them - those with larger fingers may have an issue. Occasionally, due to the awkward angle where the small touch button are placed, inputs are not registered sometimes.
Sadly, the JW1 does not have independent volume controls, and one needs to control the volume at the source (eg DAP, phone, computer).
I'm glad to report that this TWS set can be used as a mono or paired mode, which is pretty useful.
These are what the flashing lights on the JW1 indicate:
BATTERY
Fiio advertises that the JW1 can hit 6 hours on a single charge, or 18 hours if the charges contained in the charging case are added. That's quite decent for a budget TWS set, and on my field tests, the rated battery values are thereabouts (at moderate listening volumes).
Bear in mind that as per most electronics, battery life is expected to decrease with repeated charge cycles, but with the charging case, the JW1 should comfortably get most users through the day (or even a few days!).
Charging time is about 1.5 hours for the JW1, and an additional 1.5 hours for the case.
These are what the lights indicate on the charging case:
CONNECTIVITY/USAGE
I had no issues pairing the JW1 with multiple Bluetooth devices (eg windows, android and apple based, and even some DAPs), they recognized the JW1 immediately without fuss.
The JW1 supports BT 5.3, but only has AAC and SBC codecs. Sadly, LDAC, aptX Adaptive and aptX are not supported codecs.
Thankfully, Bluetooth connectivity is good. The BT range is about 15 metres with no obstructions, or 10 metres with obstructions. I had minimal drop outs utilizing the JW1 for the past few weeks. There's also just a very slight lag during music or videos, which is quite acceptable in my book.
Unfortunately, there is no EQ or app available, and the touch buttons are not customizable. The JW1 does support various voice assistants, for those that use these.
SOUND
Tonally, the JW1 is a midcentric TWS. There's some loss of low bass and higher treble, which is not unexpected due to the open-backed design. However, this open-backed concept confers a satisfyingly large soundstage, in depth, height and width, and this expansive soundscape is really unexpected for the coin.
With this midcentric profile, we have the mid-
bass at neutral, with a roll-off in the sub-bass. This TWS is definitely not for bassheads, but thankfully, the bass quality is fast and clean. We have no mid-bass bleed, with acceptable texturing and rapid bass speed. No smearing of basslines are heard even on complex bass solos.
The
midrange is very clean and transparent, with no big bass to encroach here. When used at low to moderate volumes (and assuming one is not jacking up the volume to overcome outside noise from the lack of isolation), the upper mids are forwards without being shouty.
The
treble is quite well-dosed, with decent extension. This TWS is not the most extended sparkly or airy, with a higher treble roll-off, though it should be safe for treble sensitive folk. Sibilance is kept minimal.
Timbre is very natural for acoustic instruments and vocals.
Technically, the JW1 is probably more for lay consumers than dyed-in-the-wool audiophiles. We won't be expecting pinpoint imaging and top-notch instrument separation and micro-detailing, but the JW1 should be good enough for most on-the-go usage where critical listening is not required. As alluded to, the huge soundstage is a big feather in the cap of this TWS, with music never sounding compressed.
Other than for music, this TWS will be a great companion for calls, videos, online meetings, and podcasts. Using them for these purposes, I could hear voices clearly with no issues, with the midcentric tuning pushing vocals through in the mix.
COMPARISONS
The
Moondrop Nekocake has better passive isolation, with ANC also available. In stock tuning, the Nekocake preserves more bass frequencies, though the bass isn't as tight and bleeds, compared to the JW1. The Nekocake also has a Moondrop Link App, which allows configuration of touch buttons and 5 preset EQ settings.
The Nekocake has weaker technical performance, with inferior soundstage, instrument separation and imaging. The Nekocake sounds claustrophobic in comparison. The Nekocake also has inferior battery, with 4 hours on a single charge (or 12 hours with the charging case). Bluetooth connectivity and range is about similar.
CONCLUSIONS
The JW1 is a solid introductory TWS for newcomers to the audio hobby, or even for lay consumers who want something for online meetings, podcasts, or calls. Boasting decent price-to-performance ratio, the JW1 has a nice accessory spread with a secure fit and comfortable ergonomics.
Battery life is quite creditable, with very stable Bluetooth connectivity and range. The JW1's open backed design bestows a superb soundstage, and also allows users to have situational awareness on-the-go. Thus, the JW1 can be used for sports, or even outdoors as such.
However, this is a double-edge sword - the lack of passive isolation contributes to some sound leakage and a sub-bass roll-off. Thus, bassheads might want to look elsewhere for their bass kicks. In terms of sonic fidelity, the midcentric tonality is quite nicely done, with timbre a particular highlight.
There are some minor quirks to nitpick, such as no independent volume controls, insensitive touch buttons, lack of support for some higher res BT codecs, and no EQ/app/customizable buttons available. However, considering the JW1's affordable price, it definitely does more things right than wrong, and would be a functional and useful gadget for myriad indoor and outdoor activities.
