The Jrwaro S13-BK01 earbuds feature an understated design that comes in an all-black or black-green colorway. The earbud housing has an angled nozzle that inserts comfortably. The plastic construction feels decent but could benefit from a more premium build. The matte texture resists fingerprints. The charging case has a matching color and smooth rounded edges.

Sound Performance

With their 13mm drivers, the Jrwaro S13-BK01 Wireless Earbuds deliver surprisingly good sound across the frequency range. The audio profile is slightly bass-boosted while maintaining clear mids and highs.

Music genres like EDM, hip hop, and pop shine on these earbuds. Podcast and audiobook listening is also enjoyable. Volume levels can be pushed quite high before distortion kicks in.

For calls, the dual-mic noise cancellation works decently to reduce ambient noise. Callers report my voice sounds clear even in noisy environments. The earbuds do a good job isolating the other person’s voice as well.

Microphones & Noise Cancellation

For calls and voice assistants, the dual microphone array works effectively to reduce ambient noise. Callers reported my voice sounded clear in a range of environments from quiet rooms to busy streets. Noise cancellation is not as advanced as premium earbuds but very capable given the affordable pricing.

Battery Life

The 48 hours total playtime is one of the major selling points of the Jrwaro S13-BK01 Wireless Earbuds. I regularly went multiple days between charges during my testing.

The earbuds themselves last around 8 hours on a single charge. The compact charging case provides an additional 2.5 charges worth of power.

When it’s time to recharge, the fast charging feature is handy. I was able to get 1.5 hours of playback from a 10 minute charge - perfect for a quick top up before heading out.


The Jrwaro S13-BK01 Wireless Earbuds uses Bluetooth 5.3 for fast and stable wireless connection to phones, tablets, and laptops. Pairing was quick and painless in my testing. The earbuds automatically turn on and connect to the last paired device when removed from the case, which is very convenient.


Onboard controls include tap and press gestures for managing music, calls, volume and voice assistants:
- Play/pause: single tap either earbud
- Next track: double tap right earbud
- Previous track: double tap left earbud
- Answer/hang-up call: single tap either earbud
- Reject call: press either earbud for 2 seconds
- Volume up/down: press and hold either earbud


The IPX7 waterproof rating allows the Jrwaro S13-BK01 Wireless Earbuds to withstand sweat, splashes and rain. I used them for intense workouts without issues. They cannot be fully submerged, so are not suitable for swimming. Overall the waterproofing provides useful protection during active use.

Use Cases:

The Jrwaro S13-BK01 earbuds really shine for active use cases where long battery life is key. I used them on daily runs and workouts without worrying about recharging constantly. The IPX7 waterproof rating gave peace of mind when sweating heavily. The earbuds stay secure and comfortable even during high intensity training.

These are also great for travel and commuting. I never had to pack a charging cable because the battery lasted multiple days of heavy use. The noise cancelling mics worked nicely to isolate voices when making calls on the go.

User Feedback Analysis:

Scouring through countless user reviews, it’s clear the Jrwaro S13-BK01 earbuds have made many buyers very happy. The overwhelming praise for battery endurance confirms the near-magical 48 hours of playtime is no exaggeration. Users rejoice at being untethered from constant recharging.

The comfortable fit also earns kudos from reviewers. Many describe the earbuds as “fitting like a glove” and not budging during exercise. This clever design triumphs where some competitors disappoint with poorly shaped buds that slip out constantly.

Noise isolation gets high marks, with users noting the snug seal and deep earbud insertion work together to passively muffle ambient sound. This complements the mics’ active noise cancelling to make calls and music really pop.

While audio quality satisfies most for the price, some finicky listeners remark on the heavy bass and lack of customizability. Indeed, head-thumping EDM fans will adore the powerful low end, but those preferring a neutral reference sound may be slightly disappointed.

Constructive feedback on room for improvement includes expanding mobile app functionality, adding premium metal or ceramic finishes, and tweaking the controls. Users universally agree the minor gripes pale in comparison to the positively epic battery performance though.

In summary, real-world reviewers widely state the Jrwaro S13-BK01 earbuds exceed expectations and provide absurd value. The marathon battery life justifies the purchase alone for many. Factor in pleasant sound and comfort, and these are easy to recommend for those craving endless playback.

Given the marathon battery performance, IPX7 rating, and overall solid feature set, the Jrwaro S13-BK01 earbuds deliver excellent value. They compete with models costing twice as much. For those needing long playback autonomy for travel or fitness, these are hard to beat at this price point.


For those seeking wireless earbuds with marathon battery life, solid sound quality, and decent noise cancelling microphone performance, the Jrwaro S13-BK01 Wireless Earbuds ticks all the boxes.
