The back of Teenage Engineering’s EP-35 opens to reveal a compartment for cables and accessories. It’s a wonderfully unglamorous feature to put on a music gadget. An amp can look perfectly composed in a product photo, but taking it anywhere means figuring out where the supporting cast goes. Giving those loose pieces a home inside the speaker feels like an acknowledgment of how people actually use their equipment.
That practical streak extends beyond storage. Listed for sale at $399, the EP-35 combines a portable speaker, an instrument amplifier, and a USB audio interface. It accepts guitar, microphone, line-level, Bluetooth, and USB audio, with multiple sources able to play together. The problem it addresses is straightforward: playing guitar over a backing track, or adding vocals, shouldn’t require assembling a small equipment department. Here, those connections meet in one box.

Visually, the EP-35 has the charm of equipment that might belong in a very stylish school science lab. Its gray body, square grille, integrated handle, and orange accents are deliberately matter-of-fact. I like that the speaker drivers remain visible behind the grid. They give the front a slightly awkward, almost characterful expression. Nothing about the proportions suggests an object desperate to disappear into your decor, which is part of its appeal.
The controls make a similar impression. There are physical dials for choosing effects and adjusting their intensity, with eight presets each for guitar and microphone. That’s an approachable arrangement: select a sound, turn a control, hear what changes. I’d rather see that direct relationship on something intended for casual playing than a screen full of options. The microphone effects even include presets called “robo choir” and “frog,” which gives you a fair idea of the intended mood.
The USB audio interface is less visually entertaining but potentially more useful. Connect the EP-35 to a computer and it can serve as a recording interface, giving the same object a role at a desk after it comes home. That continuity makes sense to me. A portable device earns its shelf space more easily when it doesn’t become redundant the moment you’re near a power outlet and a laptop.
Inside the storage compartment, Teenage Engineering has also included a small camp light. It can illuminate the compartment automatically when opened, stay on, or react to incoming audio in disco mode. Tilting the speaker backward makes those LEDs display the battery level. Some of this is useful, some is cheerfully unnecessary. I’m happy with that balance. Checking a battery through a small physical gesture is a more memorable interaction than another tiny percentage readout.
Portability does need a little perspective, though. At about seven pounds, the EP-35 is something you carry by its handle, not casually toss into a small shoulder bag. Teenage Engineering rates battery life at 12 hours with the volume set to five, so that figure shouldn’t be treated as an all-day guarantee at any loudness. It’s also splash-resistant rather than waterproof. Those distinctions matter if the appealing camp light has you mentally packing it for a weekend outdoors.
There’s room to expand the setup, too. Two EP-35s can play Bluetooth audio in stereo through broadcast mode. Teenage Engineering’s instructions let you assign left and right channels by tilting each speaker before starting that mode. Connected instruments take a different route: linking their sound between speakers requires a line-out-to-line-in cable. That’s worth understanding before imagining a completely wireless mini stage. The wireless convenience applies specifically to Bluetooth playback.
For me, the $399 price makes the most sense if those musical connections will get regular use. Someone who only wants background listening would be paying for considerable capability they might never touch. Sound quality still needs a listening test; clever packaging can’t settle that question. But I appreciate the attention paid to what happens between sessions. The music stops, the cables come out, and the EP-35 gives you somewhere to put them. That’s a modest design decision with a very recognizable payoff.
