# Teenage Engineering OB–4 Buyer Guide

Whether OB–4 is the right Teenage Engineering tool for a design-forward portable speaker with physical playback, FM, and “disk” features.

Buy OB–4 when you want a design-forward portable speaker with physical playback, FM, and “disk” features; the main tradeoff is far higher price than ordinary Bluetooth speakers and a sound/features mix that only makes sense if you want the object’s character. The official US feed showed $579–$1,150 by listed color/design SKU on 2026-10-18; its status was mixed in-stock/out-of-stock and discontinued variants.

## Key Stats

- Official US price: $579–$1,150 by listed color/design SKU - Official store feed observation on 2026-10-18; Amazon price remains unverified.
- Official state: Mixed in-stock/out-of-stock and discontinued variants in the official US feed - Official US feed state; not an Amazon offer claim.
- Core role: Portable Bluetooth/FM speaker and media instrument - a design-forward portable speaker with physical playback, FM, and “disk” features.
- Main constraint: far higher price than ordinary Bluetooth speakers and a sound/features mix that only makes sense if you want the object’s character - Check this before paying for the compact workflow.

## Quick Read

- The fit: OB–4 is a portable listening object with a replay interaction. - Choose it when high-quality portable listening and rewind/loop play matter; a Sonos Move 2 or Marshall Kilburn III is the ordinary Bluetooth-speaker comparison.
- The reason: Bluetooth, line input, FM radio, disk mode, and a rolling two-hour replay buffer. - The buffer lets you rewind and loop recent playback, but it is not a saved recording library.
- The catch: The design and portable listening role carry more of the price than a generic speaker feature list. - Compare single-speaker use with a two-speaker stereo setup and name the color/design or magic-kit configuration explicitly.

## Bottom line

**Buy OB–4 for portable listening with rewind.**

[OB–4](https://www.amazon.com/dp/B08WR5VHYB?tag=sourcebottle-20&linkCode=ll1&language=en_US&ref_=as_li_ss_tl) Choose it when listening itself—portable, high-quality, and rewindable—is the job. Its replay buffer is a temporary two-hour listening interaction rather than saved recordings. Fresh official rows showed $579 for black EU/US variants and $1,150 for the Off–White EU variant; those checked rows were out of stock on 2026-10-18. Compare a Sonos Move 2 or a two-speaker stereo setup when ordinary playback or room imaging is the real job.

## Product shape

**A speaker whose replay buffer changes listening.**

OB–4 is a portable Bluetooth/FM/line speaker with disk-mode sound tools and a rolling two-hour replay buffer. The replay function changes how you revisit live radio, Bluetooth, or line playback, but it does not create a library of saved recordings. Buy it for listening and interaction first, then choose among standard black, red, gray, navy, ochre, orange, or white variants, Off–White/Mind Games designs, and red/white portable magic kits; region rows differ.

## Comparison ladder

**Compare listening roles, not raw speaker counts.**

| Choice | Product | What you gain | What you give up |
| --- | --- | --- | --- |
| Ordinary portable speaker | Sonos Move 2 or Marshall Kilburn III | Choose a mainstream speaker when convenience, app ecosystem, and lower-complexity playback matter more. | You give up OB–4’s replay buffer, FM/disk interaction, and distinctive portable object. |
| Target | [OB–4](https://www.amazon.com/dp/B08WR5VHYB?tag=sourcebottle-20&linkCode=ll1&language=en_US&ref_=as_li_ss_tl) | Choose it when portable listening and rewind/loop interaction are the main use. | You pay for a specialized listening experience rather than generic volume alone. |
| Stereo alternative | Two-speaker stereo setup | Choose a stereo pair when room imaging and left/right separation matter more. | You give up OB–4’s one-box portability and replay behavior. |
| TE lateral | [OD–11 stereo alternative](https://www.amazon.com/dp/B017YSGQHG?tag=sourcebottle-20&linkCode=ll1&language=en_US&ref_=as_li_ss_tl) | Choose OD–11 when fixed-room hi-fi placement and stereo pairing are more important. | It is less portable and has a different documented control path. |

## Buying matrix

**Where OB–4’s replay workflow matters.**

| Use case | Fit | Why |
| --- | --- | --- |
| Portable listening | Strong | Battery, Bluetooth, FM/line input, and the replay interaction are the reason to buy it. |
| Saved recordings | None | The rolling buffer is for rewind/loop interaction, not a saved recording archive. |
| Room stereo | Mixed | Compare a two-speaker setup or OD–11 pair when imaging matters. |
| Configuration | Needs care | Check whether the listing is a standard speaker, an Off–White/Mind Games design, or a red/white portable magic kit, then confirm color, region, and package contents at checkout. |

## Review signal

**Independent reviews explain the tradeoff better than the feature list.**

| Signal | What it supports | Confidence |
| --- | --- | --- |
| Root-Nation | Root-Nation describes OB–4 as a portable speaker with 92dB stereo output, unusual controls, and a design-led feature set, while recognizing that ordinary speakers can be cheaper. | Professional hands-on review |
| Android Central | Android Central highlights Bluetooth, 3.5mm input, FM, disk-mode sounds, physical controls, and the premium price relative to mainstream Bluetooth speakers. | Professional review or launch-context source |
| r/teenageengineering | Owners disagree on whether the sound and interaction justify the price; the spread is useful community signal, not a controlled listening test. | Community signal; anecdotal |

## Mechanism

**How OB–4 treats playback and replay.**

| Area | What the sources describe | Buyer consequence |
| --- | --- | --- |
| Playback | Bluetooth, line input, FM radio, and disk-mode sound controls. | Choose the source path before buying; the speaker is designed around listening and interaction. |
| Replay buffer | Rolling two-hour buffer for rewind and loop play. | It lets you revisit recent playback but does not save a file for later editing. |
| Configuration | Standard black/red/gray/navy/ochre/orange/white variants, Off–White/Mind Games designs, and red/white portable magic kits appear under region-specific rows. | Read the package contents and region rather than comparing opaque bundle identifiers. |
| Ownership | Official price observation is dated to 2026-10-18. | Confirm current seller, condition, price, stock, and return terms at checkout. |

## Decision

**Choose OB–4 when the listening interaction matters.**

- Choose OB–4 when its portable listening and replay behavior will be used often; choose a mainstream Bluetooth speaker or stereo pair when the job is ordinary playback or room imaging.
- Do not describe the replay buffer as saved recordings; it is a rolling interaction with recent playback.
- Compare Sonos Move 2 or Marshall Kilburn III for ordinary portable Bluetooth use, and a two-speaker setup for stereo imaging.
- Check color/design, region, and magic-kit contents at checkout because official package rows represent configurations, not new speaker architectures.

## Edge cases

**Separate replay from recording, and name the configuration.**

- Do not describe the replay buffer as saved recordings; it is a rolling interaction with recent playback.
- Compare Sonos Move 2 or Marshall Kilburn III for ordinary portable Bluetooth use, and a two-speaker setup for stereo imaging.
- Check color/design, region, and magic-kit contents at checkout because official package rows represent configurations, not new speaker architectures.
- Test the line, Bluetooth, FM, and disk-mode paths you expect to use before relying on it for a specific listening setup.

## Claim Table

| Where | Claim | Confidence | Source | Caveat |
| --- | --- | --- | --- | --- |
| Product shape | OB–4 is the portable bluetooth/fm speaker and media instrument in this comparison. | High | Teenage Engineering (te-ob-4-official) | The role is an editorial summary of the current official product page; recheck the exact model and variant before buying. |
| Product shape | The official page and family catalog identify OB–4 as a portable Bluetooth/FM speaker with line input, replay/disk features, and color/design variants; the accepted identity row covers a generic OB–4 listing. | High | Teenage Engineering (te-ob-4-official) | Manufacturer specifications describe the feature set; they do not guarantee every workflow or host combination. |
| Buying matrix | The official US feed showed $579–$1,150 by listed color/design SKU for OB–4 on 2026-10-18; the listed state was mixed in-stock/out-of-stock and discontinued variants in the official US feed. | High | Teenage Engineering (te-price-feed) | This is an official store observation, not a live Amazon offer or a guarantee that every color, bundle, or seller shares the same state. |
| Review signal | Root-Nation describes OB–4 as a portable speaker with 92dB stereo output, unusual controls, and a design-led feature set, while recognizing that ordinary speakers can be cheaper. | Medium | Root-Nation (review-root-ob4) | This is an independent review of a specific unit and time; it is not a universal performance guarantee. |
| Review signal | Android Central highlights Bluetooth, 3.5mm input, FM, disk-mode sounds, physical controls, and the premium price relative to mainstream Bluetooth speakers. | Medium | Android Central (review-android-ob4) | The review’s sample, firmware, and comparison set may differ from a current unit. |
| Review signal | Owners disagree on whether the sound and interaction justify the price; the spread is useful community signal, not a controlled listening test. | Medium | r/teenageengineering (community-ob4) | Community reports are anecdotal and selection-biased; use them to form inspection questions, not failure rates. |
| Decision | OB–4 makes sense when a design-forward portable speaker with physical playback, FM, and “disk” features; the main tradeoff is far higher price than ordinary Bluetooth speakers and a sound/features mix that only makes sense if you want the object’s character. | Medium | Root-Nation (review-root-ob4) | Fit depends on the reader’s workflow, budget, and tolerance for the stated limitation. |
| Edge cases | The relevant connection, configuration, and ownership caveats for OB–4 are material to the buying decision: Do not buy OB–4 solely for maximum sound per dollar; independent reviews explicitly compare it with cheaper mainstream speakers. | High | Teenage Engineering (te-ob-4-official) | Check the current guide and included accessories for the exact revision before purchase. |
| Mechanism | The official package rows cover standard/design-color/region variants and named portable magic-kit configurations; confirm the package contents rather than comparing opaque identifiers. | High | Teenage Engineering (te-price-feed) | These are dated official US feed rows; current merchant offers, stock, seller, fulfillment, delivery, bundle contents, warranty, and returns remain unverified. |
