Wireless earbuds have become increasingly compact, but smaller does not always mean more comfortable or more suitable for active use. Zombies Cat B22 takes a different approach with an open-ear earclip design that sits around the ear rather than sealing the ear canal.
That design is paired with Bluetooth 6.0, 14mm dynamic drivers, claimed 720° panoramic sound, a built-in microphone, and a small warm-colored safety light. Instead of trying to compete purely on conventional earbuds specifications, the B22 is designed around the idea of keeping music available while maintaining a more open connection with the surrounding environment.
According to the Banggood listing, the B22 supports Bluetooth 6.0, uses 14mm speakers, offers up to 4.5 hours of playback from the earbuds themselves and up to 20 hours when combined with the charging case.
The B22’s biggest idea is its open-ear design
The most interesting part of the Zombies Cat B22 is not actually Bluetooth 6.0. It is the way the earphones are worn.
Rather than pushing an earbud into the ear canal, the B22 uses an earclip-style open-ear structure. This can be appealing to people who dislike the plugged-in sensation of traditional in-ear headphones or want to remain more aware of their surroundings while listening.
That makes the B22 sports headphones particularly relevant to walking, commuting, cycling and other situations where completely isolating yourself from environmental sound may not be desirable.
It also changes the way the headphones should be evaluated. The goal is not simply maximum isolation. Instead, the B22 is built around a balance between personal audio and environmental awareness.
14mm drivers give the B22 a larger audio foundation
Inside the compact earphones are 14mm dynamic drivers.
A larger driver does not automatically guarantee better sound, but it gives the B22 a substantial hardware foundation for producing bass, vocals and higher-frequency details. For an open-ear design, that can be particularly important because there is no sealed ear canal to create the same acoustic conditions as conventional in-ear headphones.
The product listing describes the 14mm drivers as being designed for a broad soundstage with stronger bass and clear treble.
The stated frequency response is 20Hz–20kHz, covering the commonly specified range for consumer headphones.
What does “720° surround sound” mean here?
The B22 also promotes 720° panoramic sound, which is one of its more unusual specifications.
This should be understood as a spatial-audio presentation rather than literally having sound physically travel in every direction around the listener. The idea is to create a wider and more immersive sense of positioning than conventional stereo playback.
That could make movies, games and music feel more spacious, although the real-world effect will depend on the recording, device and listening environment.
For buyers, the more meaningful takeaway is that Zombies Cat is positioning the B22 as an immersive open-ear headphone, rather than a basic wireless sports earbud.
Bluetooth 6.0 focuses on connection and responsiveness
The B22 uses Bluetooth 6.0 and supports HSP, HFP, A2DP and AVRCP profiles. The listed transmission distance is up to 10 meters.
For everyday users, the important part is less about the Bluetooth version number itself and more about how the headphones fit into daily use.
Bluetooth 6.0 is intended to provide a modern wireless connection, while the supported profiles cover common functions such as music playback, hands-free communication and remote media control.
The listing also highlights low latency for gaming and video. That makes the B22 potentially more versatile than headphones designed exclusively for music listening, although actual latency can vary depending on the connected phone, computer or game system.
The built-in warm light is more than decoration
One of the B22’s most distinctive physical features is its integrated warm safety light.
The light is positioned as a visibility feature for activities such as night running and cycling. Rather than functioning purely as an RGB-style visual effect, the concept is to make the wearer easier to notice in darker surroundings.
This is a clever addition because open-ear headphones are already aimed at active users. A small visibility feature gives the design another practical purpose.
However, the light should be considered an additional visibility aid rather than a replacement for proper cycling or running safety equipment.
Battery life is designed around shorter daily sessions
The B22 uses a 40mAh battery in each earphone and a 300mAh charging case.
Banggood lists approximately 4.5 hours of playback from the earbuds alone and up to 20 hours with the charging case. Charging the case and earbuds is listed at around one hour.
That makes the B22 better suited to several shorter listening sessions than extremely long continuous use.
For example, a commute, workout, walk or evening gaming session can fit comfortably within the stated earbud runtime. Once the earbuds are returned to the case, the additional battery capacity extends the overall listening time.
As always, actual runtime can vary with volume, connection conditions and other usage factors.
The earclip format makes the B22 a sports-oriented headphone
The B22 weighs approximately 43 grams as listed for the product, with dimensions of 60 × 28 × 52mm.
Its physical design is clearly aimed at people who want something different from conventional TWS earbuds.
The earclip structure avoids the need for a traditional silicone ear tip, while the open-ear configuration can make the headphones more suitable for users who prefer a less enclosed listening experience.
That said, fit is highly personal. An earclip that feels secure for one person may not feel identical for another, so the B22’s design should be viewed as an alternative to conventional earbuds rather than a universal replacement.
A microphone makes it useful beyond music
The B22 includes a built-in microphone and supports the standard Bluetooth calling profiles listed by Banggood.
This means the headphones can also be used for calls and voice communication rather than functioning only as a music player.
For people who frequently switch between podcasts, music, phone calls and video content, that makes the B22 a more practical everyday accessory.
Who should consider the Zombies Cat B22?
The B22 makes the most sense for users who specifically want an open-ear Bluetooth headphone rather than a conventional sealed earbud.
It could be particularly interesting for:
- Runners and walkers who prefer an open listening style
- Cyclists looking for headphones with an additional visibility feature
- Commuters who dislike the pressure of in-ear tips
- Users who want larger drivers in an open-ear design
- People interested in Bluetooth 6.0 headphones
- Gamers and video viewers looking for a more spacious audio presentation
It may be less suitable for someone whose first priority is strong passive isolation or deep noise blocking, because the open-ear concept is fundamentally designed around a different listening experience.

Final thoughts
Zombies Cat B22 earphone is interesting because it does not try to be another ordinary pair of TWS earbuds.
Its combination of an open-ear earclip structure, 14mm dynamic drivers, Bluetooth 6.0 and built-in warm safety lighting gives it a clearly defined identity. The claimed 720° panoramic sound is another attempt to make the listening experience more immersive without returning to a conventional closed-in design.
The most important question for potential buyers is therefore not whether the B22 has the longest battery life or the most aggressive specification sheet. It is whether an open-ear listening experience fits their daily routine.
For sports, commuting and casual listening where environmental awareness matters, the B22 offers a distinctive alternative to traditional in-ear headphones.
