Bose Ultra Open Earbuds review: open sound, clear compromises

The Ultra Open Earbuds are Bose's take on listening without shutting the world out. They clip over the ear rather than plugging the canal, so traffic, station announcements and a colleague's question still get through. That makes them a strong fit for some buyers and an expensive mismatch for others. The useful question is what the open design means in daily use, where it falls short and how to decide before you buy.

The product is a true wireless pair with a barrel that sits behind the ear and a speaker that rests near the ear opening. Nothing goes into the ear canal. Bose calls the approach open-ear audio; the practical effect is that you hear your surroundings alongside your music, podcast or call. It is not a noise-cancelling product and it is not aimed at critical listening in a quiet room. It is for people who want a soundtrack to the day without losing contact with it.

The clip is the whole idea. A flexible joint lets the two halves grip the back of the ear, with the speaker floating just outside the canal. There is no tip to push in, no suction and no pressure build-up, which is why people who dislike normal earbuds often get on with this shape. The trade-off is that fit is more dependent on ear shape. Thin ears, thick glasses arms and helmet straps can all change how secure they feel. For desk work, walking and light training, the light, open hold is the main attraction.

Open-ear sound is best described as clear, airy and unbothered by the room. Vocals and podcasts come across well, and because nothing is sealed, the presentation feels wider than a typical in-ear pair. Bass is the compromise. Physics is not on your side: without a seal, deep sub-bass and physical punch are limited. The app's EQ can add some warmth, but it cannot turn an open design into a bass monster. Immersive Audio adds a more spacious effect for films and games, though some listeners will prefer it switched off for music. At high volume in a quiet room, nearby people may hear what you are playing. That is the price of staying aware.

Calls are a sensible use case because you can hear your own voice and what is happening around you. The microphones are designed to pick up speech, but an open fit cannot block nearby noise, so a windy street or a busy café is harder work than a quiet room. Controls live on the earbuds, and the Bose Music app handles EQ and Immersive Audio. There is no ANC switch to fiddle with, because there is no ANC. The day-to-day appeal is convenience: pick them up, clip them on, and stay in the room.

Bose rates the earbuds for up to 7.5 hours of playback and the case for up to 27 hours in total. That is enough for a working day and a commute, though heavy all-day use will still mean a top-up. IPX4 means sweat and splashes are covered, not swimming or a soaking. The case is part of the package and adds bulk to a pocket, so it is better suited to a bag. Bluetooth 5.3 is current enough for typical phone and laptop use, and the app is where you manage settings.

These are for people who want music or podcasts without a bubble. Cyclists and runners who need to hear traffic, office workers who need to catch a colleague's question, parents listening while a child is in the room, and anyone who finds sealed earbuds uncomfortable all fit the brief. They are also a good choice for long listening at low-to-moderate volume, where the open sound feels natural rather than thin.

Skip them if your main listening happens on trains, planes or busy roads where you want the world turned down. Skip them if bass weight matters more than awareness, or if you need one pair to do everything. Skip them if you share a quiet office and like to turn the volume up. And skip them if the premium price would stretch you: an open-ear design is a specialist tool, not the most versatile way to spend a headphone budget.
