If you want adjustable noise cancellation and clear calls in an over-ear design, choose Bose Headphones 700; if you need compact true wireless earbuds with a secure fit for exercise, choose Sennheiser Momentum True. For a kid, I’d start by considering fit and how the headphones will be used: the Bose covers the ears, while the Sennheiser sits inside them.
Bose Headphones 700 vs Sennheiser Momentum True at a Glance
• Bose Headphones 700: Over-ear design, 11 noise-cancellation levels and a microphone system designed to pick up your voice in noisy or windy surroundings. Trade-off: its 20-hour wireless battery life is shorter than the Sennheiser’s stated total listening time with its case.
• Sennheiser Momentum True: Compact earbuds with Adaptive Noise Cancellation, Transparency Mode, multipoint connectivity and a 28-hour total battery figure with the charging case. Trade-off: the in-ear fit needs to suit your ears, and getting the right tips matters for sound and call performance.
• Choose Bose for over-ear listening, calls and controls that don’t require reaching for your phone.
• Choose Sennheiser for a pocketable design, exercise use and the option to stay aware of your surroundings with Transparency Mode.
The Bose Headphones 700 is the straightforward pick if you want a traditional over-ear pair for music, podcasts, video and calls. Its active noise cancellation has 11 levels, so you can adjust how much outside sound you want to reduce rather than treating noise cancellation as a single all-or-nothing setting. Bose also describes the sound as balanced, with clear detail and full bass.
Calls are a major part of the design. The microphone system is intended to adapt to noisy and windy environments and isolate your voice, which makes the Bose a natural fit for video calls, phone conversations or listening while moving through a busy setting. Touch controls sit on the earcups, and Alexa and Google Assistant are available through voice access. The stainless-steel headband and tilted earcups are designed for comfortable wear over longer stretches; wireless battery life is up to 20 hours.

The Sennheiser Momentum True is a true wireless in-ear option for someone who wants a small listening setup for travel, sports and exercise. Its compact design comes with silicone ear adapters in XS, S, M and L, plus fins in S, M and L. Those options give you more ways to tune the fit than a one-shape-fits-all earbud, but the fit still matters: the wrong tip or an insecure placement can affect sound and call performance.
Its listening features are flexible. Adaptive Noise Cancellation adjusts to changes in surrounding noise, while Transparency Mode lets outside sound back in when you want more awareness. The built-in equalizer, presets and sound personalization provide ways to tailor the audio. Sennheiser also specifies multipoint connectivity, allowing connection to two devices, and three noise-cancelling microphones on each earbud for voice pickup.
The earbuds are IPX4 splash resistant, a useful detail for exercise or exposure to light splashes. Sennheiser gives them seven hours of battery life, with 28 hours of overall play time when the case is included; the case supports Qi wireless charging. I’d choose them if portability, a more secure in-ear fit and exercise-friendly features matter most. I’d skip them if you dislike earbuds in your ear canals or want an over-ear design. They are also not a match for searches such as “cheap open ear earbuds” or “best sweat resistant bone conduction headphones”: these are in-ear earbuds, not open-ear or bone-conduction headphones.
• Best for over-ear listening → Bose Headphones 700. The earcups sit over the ears, which is a clear difference if you prefer headphones to earbuds.
• Best for adjustable noise cancellation levels → Bose Headphones 700. Its active noise cancellation offers 11 levels; Sennheiser instead describes an adaptive system that adjusts as surrounding noise changes.
• Best for adapting to changing noise → Sennheiser Momentum True. Adaptive Noise Cancellation is designed to respond to changes in the environment, and Transparency Mode can bring outside sound back in.
• Best for calls in noisy or windy conditions → Bose Headphones 700. Its microphone system is specifically described as adapting to noisy and windy surroundings to pick up your voice.
• Best for exercise and light splashes → Sennheiser Momentum True. Its compact in-ear design is intended for sports and exercise, and its IPX4 splash resistance adds a relevant practical feature.
• Best for stated battery time with the case included → Sennheiser Momentum True. It lists 28 hours overall with the charging case, compared with up to 20 hours of wireless battery life for Bose. The figures describe different setups, so they are not a direct measure of one charge.
• Best for two connected devices → Sennheiser Momentum True. Multipoint supports connection to two devices.
• Best for hands-free voice assistant access and earcup touch controls → Bose Headphones 700. It offers access to Alexa and Google Assistant, along with touch controls on the earcups.
The fit question may matter as much as the feature list. If you are looking for wireless earbuds for side sleepers, neither product’s information establishes that either design is suitable for sleeping on your side. The Bose is over-ear; the Sennheiser sits in the ear, but its compact design alone does not guarantee comfort with pressure against a pillow. I would not choose either on that basis without confirming that the shape works for you.
I’d choose the Bose Headphones 700 for a kid if the main job is listening at home, watching video or taking calls, because its over-ear format and adjustable noise cancellation suit those uses. The Sennheiser is my pick for a buyer who wants compact earbuds for exercise, multipoint pairing and more listening time with the case in the mix. My overall recommendation is Bose for a general over-ear setup, but the Sennheiser is the more practical fit for portable, active use.
I’d choose based on whether an over-ear or in-ear fit is more suitable. Bose is over-ear and offers adjustable noise cancellation; Sennheiser has multiple tip and fin sizes, but the earbuds need to fit securely for sound and calls to perform as intended.
Sennheiser lists seven hours from the earbuds and 28 hours of overall play time with the charging case. Bose lists up to 20 hours of wireless battery life on a single charge. Those figures use different configurations, so consider whether you want a case-based charging setup.
Bose offers 11 active noise-cancellation levels, which gives you control over the setting. Sennheiser’s Adaptive Noise Cancellation is designed to adjust as surrounding noise changes, and it also has Transparency Mode. The better fit depends on whether you prefer manual levels or an adaptive approach.
Bose is designed to isolate your voice in noisy and windy environments. Sennheiser has three noise-cancelling microphones on each earbud for voice pickup. If call performance is the deciding factor, the over-ear Bose is the more clearly specified choice for changing noisy conditions.
