General

A rare beast in the land of field recording, the Teenage Engineering CM-15 brings the rich results of a large-diaphragm condenser microphone but packs it all away in a sleek and compact, battery-powered box. And in true Teenage Engineering style, this microphone really does come in a box - a box that looks like no condenser microphone you've ever seen before. You can also do more with it, like take it on location, hook it up to a field recorder and capture the quality of audio you should only get in a studio. The CM-15 features a large, 1 inch diaphragm, the performance of which outstrips the built-in microphone that comes with most field recorders by keeping the frequency response flat and consistent, essentially kitting you out with a studio microphone that's built for the field.

The Teenage Engineering CM-15: The Details

The CM-15 microphone can be hooked up to a computer or laptop via the built-in USB-C interface, can be hooked up to pro-audio equipment and recorders via XLR and, while battery-powered, is also fully compatible with standard +48V phantom power. The This ultra-focussed, supercardioid condenser mic already comes fitted with a space-saving mini-XLR output, but also comes including a mini-XLR to XLR adapter and that's alongside a USB-C cable and a tilting stand adapter so it can be used for an array of applications, whether working at home, in the studio or in its natural habitat, on location.

Wrote the following about Teenage Engineering CM-15 Large-Diaphragm Condenser Microphone (USB/Mini-XLR/Mini-Jack)

Comparing - just on a whim - teenage engineering's slim, pocket-mic CM-15s with thousand-pound-plus Brauner VM1, Wunder CM7-S, Townsend/Sphere L22 versus an original Neumann U47, I found that the CM-15 mics have the 'punch' and low-frequency 'density' of the U47 far more than any of the others! ..They don't quite have the DETAIL of the VM1, and they have a broader pickup pattern than the others, so a pair of them for stereo may blend left and right a bit - depends on how far apart they are - but the overall performance was the nearest to the U47 of all the others which attempt to use a similar capsule, valve/'tube', headbasket and transformer as the old U47.

The CM-15 mic is engineered from a different perspective: to get the best possible sound, and with a built-in pre-amp, built-in battery & phantom power, XLR, 3.5mm and USB-C outputs, and smallest size ..and INCIDENTALLY being the closest to a U47 or anything I've yet heard.

What a bargain! - No power supply needed, no phantom needed, two extra stages of gain built-in, and just slip in your pocket. Buy two for stereo!
