B2 Reading Pen
Four-button OID 3.0 reading pen on the proven SONIX 95303 platform with a large child-friendly tip, built-in TF storage, Micro USB, earphone jack and a 450 mAh rechargeable battery in a durable glossy housing. The standard choice for school tenders, classroom sets and publisher programs; multi-color housing, logo printing and preloaded audio available.
The B2 Reading Pen is the four-button version of our most-trusted entry platform: the same proven SONIX 95303 electronics, OID 3.0 recognition and 450 mAh battery as the B1, with direct mode and volume controls on the housing for programs that need more than power and volume. In the industry these devices are also widely called talking pens.
The B2 works fully offline with your OID-printed books, cards and posters. Programs, languages and audio are preloaded onto the built-in TF storage in the factory — no app, no WiFi and no account for the end user. With its self-explanatory button layout and durable glossy housing, the B2 is the model most often shortlisted for school tenders, classroom sets and publisher programs that ship the same configuration in volume.
Key features
OID 3.0 recognition
Third-generation optical identification reads OID codes printed on books, flashcards and posters quickly and reliably, in dense page layouts.
SONIX 95303 platform
A mature, mass-produced main-control chipset with a stable supply chain and well-understood tooling — the backbone of our entry range.
Large pen tip
The chunky SONIX large tip is forgiving for young children and for classroom use on thick pages, posters and flashcards.
Built-in TF storage
Audio and OID content ship on a factory-preloaded internal TF card, invisible to the user — uniform configuration across every unit in a tender lot.
Four front buttons
Power, volume and playback/mode controls sit directly on the housing, so teachers and children can operate the pen without menus or a screen.
450 mAh battery
A built-in rechargeable lithium battery charges through the Micro USB port; an LED shows power and reading status at a glance.

OEM customization on the B2
The B2 uses existing production tooling, so customization starts at much lower volumes than a brand-new housing project:
- Custom colors — plastic compound matched to your Pantone plaque on the same glossy finish; multi-color grade coding is common on school projects.
- Logo and branding — pad printing on the housing and custom-printed gift boxes, manuals and inserts.
- Audio and languages — your recordings preloaded onto the internal TF card; we also help coordinate audio mastering and OID print files.
- Book and card sets — OID printing for textbooks, readers, posters, maps and flashcards, bundled with the pen as a finished set.
- Family alternatives — need fewer buttons? Compare the two-button B1; a slimmer small-tip body? See the Q6 (Tulip).
See OEM vs ODM reading pen customization options for how color runs, logo work, packaging and new tooling are quoted.
Frequently asked questions
What is the difference between the B1 and the B2?
Both use the SONIX 95303 chip, large tip, OID 3.0, built-in TF storage and a 450 mAh battery. The difference is the interface: the B1 has two front buttons in a cartoon-bear housing, while the B2 has four front buttons for direct mode and volume control — the layout most often requested for classroom and tender use.
Can teachers update the audio themselves?
The standard B2 configuration ships with content preloaded on the internal TF card, which keeps every unit identical. If your program needs libraries that expand after sale, look at the external-TF models such as the K7 or L5.
Which housing colors are available?
Several standard colorways run on the existing tooling, and custom Pantone-matched colors are available for OEM orders. Tell us your grade-coding or branding plan and we will confirm the options for your quantity.
Does it support multiple languages?
The pen itself is language-neutral: it plays whatever audio content you load, so English, Spanish, Arabic, French, Russian and bilingual or multi-title programs are all supported.
Does the B2 work with OID 2.0 books?
The B2 reads OID 3.0 codes. If you are extending an existing OID 2.0 book library, read the OID 2.0 vs OID 3.0 buying guide or send us a sample page for compatibility advice.
