My pick for exercise is SleepPhones, especially for lower-impact routines where comfort and a 24-hour battery matter more than active noise cancellation.
SleepPhones Headphones vs DALI IO-12 at a Glance
• SleepPhones Headphones strength: soft, stretchy headband with thin speakers and up to 24 hours of battery life. Trade-off: no active noise cancellation.
• DALI IO-12 strength: active noise cancellation, Bluetooth 5.2, wired connectivity, and up to 35 hours of battery life. Trade-off: its full-size over-ear design is less low-profile for exercise.
• Choose SleepPhones for a flexible headband format that suits gentle movement, relaxation, and listening while lying down.
• Choose DALI IO-12 for immersive listening, calls, and cutting down low-frequency background noise at home or on the go.
• Neither is an in-ear exercise model, so shoppers specifically looking for clip on earbuds for exercise should look beyond these two.
SleepPhones takes a very different approach from conventional over-ear headphones. Its thin speakers sit inside a soft, stretchy headband rather than in rigid ear cups. That makes the format worth considering for activities where bulky headphones may feel awkward, including stretching, walking, or gentle exercise. Bluetooth 5 streams audio, and the stated battery life is up to 24 hours.

I’d skip SleepPhones if active noise cancellation, a wired connection, or a conventional over-ear fit is essential. Its listed controls are button-based, and the product information describes sound isolation rather than active noise cancellation. It is also specified for adults, so it is not the pick to assume will fit children; shoppers searching for kids headphones for exercise should check age suitability and fit rather than infer it from the flexible design.
The DALI IO-12 is the more traditional full-size headphone here, with over-ear square pads, a real leather headband, and a supplied travel case. Its stated features lean toward focused listening: active noise cancellation, Bluetooth 5.2 with aptX Adaptive, and a 3.5 mm connection for wired use. Battery life is listed at up to 35 hours.
That combination makes more sense for someone who wants one headphone for music, calls, travel, and home listening. The microphone is described as suitable for calls and voice recordings, while active noise cancellation is intended to reduce distractions, particularly low-frequency noise. Its touch controls also distinguish it from SleepPhones’ button controls.
For exercise, the DALI’s strengths come with a practical compromise: it is a full-size over-ear model, not a low-profile headband or a pair of clip-on earbuds. The supplied details do not establish a sweat-resistance rating, so I would not assume it is suited to strenuous workouts or wet conditions. If exercise means stationary cycling or light movement and sound isolation is your priority, it may still fit; for running or vigorous activity, the form factor deserves careful consideration.
• Best for a soft, low-profile fit during gentle exercise → SleepPhones Headphones. Its speakers are built into a flexible headband rather than bulky ear cups.
• Best for stated battery life → DALI IO-12. It lists up to 35 hours, compared with up to 24 hours for SleepPhones.
• Best for active noise cancellation → DALI IO-12. SleepPhones lists sound isolation, not ANC.
• Best for listening while lying down → SleepPhones Headphones. The thin speakers and fabric headband are a more natural match for resting on a pillow than full-size cups.
• Best for wired listening → DALI IO-12. It includes a 3.5 mm jack and cable; SleepPhones is wireless and has no headphone jack.
• Best for button controls → SleepPhones Headphones. DALI uses touch control, which some shoppers may prefer, but it is not the same control style.
• Best for calls and voice recordings → DALI IO-12. Its microphone is specifically described for those uses.
• Best fit for shoppers wanting clip on earbuds for exercise or touch control in ear headphones for exercise → neither. These are over-ear or headband headphones, not in-ear or clip-on designs.
The exercise decision comes down to what kind of session you mean. For stretching, walking, or movement where a low-profile fabric band sounds more comfortable, SleepPhones has the more exercise-friendly shape of these two. For a stationary workout where you want ANC and a conventional headphone fit, the DALI may appeal more—but its size and the absence of a stated sweat-resistance rating are meaningful considerations.
There is also a clear difference in listening priorities. SleepPhones centers on comfort and a fabric-based format, with a long battery life for a headband headphone. DALI offers wired flexibility, ANC, a microphone, and a longer stated battery runtime. The supplied specifications do not provide a direct sound-quality comparison, so I wouldn’t declare one the sonic winner based on claims alone. The useful distinction is what each is built to do: unobtrusive listening and rest versus fuller-featured, noise-canceling audio.
My Verdict
I’d choose SleepPhones Headphones for exercise, particularly for walking, stretching, and other lower-impact routines where a soft headband is more appealing than full-size ear cups.
Its 24-hour battery and washable fabric headband suit that use better than the DALI’s larger over-ear design.
For my exercise-focused pick, SleepPhones is the more sensible match—not because it does everything, but because its form factor aligns better with movement.
