- [Teenage Engineering Choir Olga](https://www.amazon.com/dp/B0BZ3SC6QW?tag=sourcebottle-20) - Target; Amazon; Check merchant. Olga is the contralto member of Teenage Engineering’s Choir. Choose the voice and physical form you want, then verify the controller and ensemble setup.

## Quick Read

- Buying call: Choose Olga for a contralto voice and the smallest figure. - Olga’s contralto register, dimensions, controller requirements, and comparison with nearby Choir voices.

## Decision

**Choose Olga for a contralto voice and the smallest figure.**

Olga has the smallest listed dimensions and lowest listed weight of the eight named dolls. That makes it worth considering when display space matters, without implying that a smaller body is quieter or better sounding. Its contralto register is lower than Ivana’s alto range; listen to both for the intended part before choosing by compactness alone.

## Compare

**Olga has a specific register and physical shape.**

| Item | Official specification | What it means |
| --- | --- | --- |
| Voice | Contralto | A characteristic vocal role, not a speaker frequency-response test. |
| Listed register | E3–C5 | The family page says solo performance can adapt beyond the characteristic role; do not treat this as a proven hard MIDI boundary. |
| Dimensions | 51 × 51 × 200 mm | Leave additional room for hands, controls, and charging. |
| Weight | 696 g | Use a stable surface and handle the wooden parts carefully. |

## Operation

**A singing instrument with a built-in repertoire.**

The solid-beech figure contains a speaker module and plays prepared songs on its own or joins other Choir dolls. A gentle tap controls play/pause, and tilting changes volume. The manufacturer specifies 3–4 hours of continuous singing. That is a battery claim, not a measured result here. Think of it as a small physical performer, not a general-purpose Bluetooth music speaker.

## Control

**Confirm Bluetooth MIDI compatibility before buying a controller.**

MIDI carries musical instructions such as notes; Bluetooth audio streaming is a different function. Teenage Engineering names OP-1 field, OP-Z, compatible Bluetooth MIDI keyboards, and Ortho Remote. The remote handles start/stop and volume; it is not a keyboard. Pairing one doll can control the group. A keyboard with USB or five-pin MIDI alone does not establish the required wireless connection.

## Setup

**Plan Olga’s charging and update access.**

The manual specifically places Olga’s charging input inside the doll: remove the head to reach it. Make sure your chosen display position lets you lift and handle the parts comfortably. Charge and test the doll individually before adding it to an ensemble. The official download page requires all participating dolls to use the same OS version. On October 18 it listed 1.2.2 with a midsummer repertoire alongside older repertoire downloads. Choose a consistent version deliberately; update files are transferred through the doll’s USB drive according to the official instructions.

## Compare

**Compare Olga with adjacent voices and the actual bundles.**

| Choice | Reason to compare | Budget or contents |
| --- | --- | --- |
| Olga | Your target contralto voice | $249 in the October 18 US catalog. |
| Ivana | F#3–D5 alto; a higher listed range and taller body. | A different named doll; verify its own offer. |
| Bogdan | E2–C4 bass; a much lower characteristic register, but a larger and heavier figure. | A different named doll; do not reuse this page’s Amazon link. |
| Mini ensemble | Carlo + Hatshepsut + Ivana; does not include Olga | $747 catalog price: three times $249, not an observed discount. |
| Full ensemble | All eight named voices | $1,992 catalog price: eight times $249; more devices to charge and update. |

## Evidence

**Listen to the timbre and test your own connection.**

Hainbach’s first-person notes describe the interest of microphone placement and an early Mac connection problem. Choirama supplies owner research and a teardown; OP Forums contains mixed controller reports, including setup mistakes later corrected. These are useful hands-on and community sources, not standardized tests of every doll or current firmware. They do not establish today’s latency, failure rate, or battery duration. This guide has not independently auditioned Olga.

## Buy

**Buy the named Olga doll, not a generic Choir listing.**
