If you want comfortable over-ear headphones with adjustable noise cancellation and clear-call features, choose Bose Headphones 700; if you need compact true wireless earbuds with a charging case, choose Sennheiser Consumer Audio Momentum. For a kid, my quick call is Bose when fit and easy-to-understand over-ear controls matter more than pocketability; Sennheiser is the smaller, in-ear option for a child who prefers earbuds and can get a secure tip fit.
Bose Headphones 700 vs Sennheiser Consumer Audio Momentum at a Glance
• Sennheiser Consumer Audio Momentum: True wireless earbuds with active noise cancellation, customizable touch controls, Smart Pause, and up to 28 hours including the case. The trade-off is that the earbuds alone provide up to 7 hours, and sound and call performance depend on a secure ear-tip fit.
• Choose Bose for an over-ear fit, adjustable noise cancellation, and a microphone system designed to isolate your voice during calls.
• Choose Sennheiser for an in-ear design, a charging case, and controls built into both earbuds.
• Neither product is described for children in its product details, so a parent should weigh the adult age-range description and the child’s fit preference rather than assume either is a kid-specific headset.
Bose is the clearer fit for someone who wants a traditional over-ear headset rather than small buds in the ear. The earcups sit over the ears, while the headband uses stainless steel and the earcups are tilted for fit. Bose lists the headset at 8.82 ounces. These details point toward a full-size option for listening at home, watching videos, or taking calls, not something as compact to carry as earbuds.
Its most distinctive practical feature is the choice of 11 active-noise-cancellation levels. That gives the listener more than a single noise-control setting to work with, whether they want to reduce distractions while listening or choose a different level for a particular setting. Bose also highlights a microphone system that adapts to noisy and windy environments, which makes this the more call-focused choice on paper. Touch controls on the earcups and access to Alexa and Google Assistant add ways to manage audio or use voice features without reaching for a phone.
Bose lists up to 20 hours of wireless battery life on one charge, Bluetooth 5, and a Bluetooth range of 10 meters. It also includes a 2.5 mm headphone jack, audio cable, USB charging cable, and carrying case. The wired option may be useful when a listener prefers a cable connection, while the case gives the over-ear headset a place to store between uses. Its stated battery charge time is 2.5 hours.
For a child, the over-ear shape may be easier to understand than earbuds: the cups go around the ears instead of needing tips fitted into the ear canals. But the product information describes the age range as adult, and it does not provide child-specific sizing or safety features. I would involve the child in checking fit and comfort rather than treating the adult-oriented design as automatically suitable.
Who should skip it: Skip Bose if the listener strongly prefers earbuds, needs a compact in-ear set, or is specifically seeking a product described for children.
Sennheiser is the more compact choice for someone who prefers true wireless earbuds. The Momentum True Wireless 2 has rounded in-ear tips, a charging case, and no headphone jack. Its wireless design avoids an audio cable between the earbuds, while Bluetooth 5.1 and a listed 10-meter range describe its connection setup. The product information gives an adult age range, so parents should pay close attention to fit rather than assume the earbuds are sized for a child.
The sound features are a major part of its appeal. Sennheiser specifies 7-millimeter dynamic drivers and a frequency range of 5 to 21,000 Hz. It describes active noise cancellation working alongside passive isolation from the earbuds’ fit, with deep bass, natural mids, and clear treble as the intended listening character. Transparent Hearing is also described as a way to bring awareness of the surroundings back into the listening experience. That combination may suit a listener who wants in-ear noise control but also values a way to hear outside sounds.
Battery life needs to be read in two parts. The earbuds are listed for up to 7 hours on a charge, while the charging case extends total listening time up to 28 hours. In other words, the longer figure includes the case; it is not the standalone runtime of the earbuds. Sennheiser lists 1.5 hours for charging the earbuds and case. Smart Pause automatically stops audio when the earbuds are removed and resumes when they are put back, while customizable touch controls on both earbuds can handle audio and calls.
Fit is the key trade-off. Sennheiser notes that tips that do not match the ear canals, or earbuds worn incorrectly, can affect sound quality and call performance. A snug, comfortable fit is therefore part of getting the intended result—not a minor detail. That matters especially for a kid, since a child may find in-ear tips comfortable, irritating, or difficult to keep secure depending on their ears and preferences.
How We Research

Updated: 2026-10-19 · 16 min read · Independent comparison
Who should skip it: Skip Sennheiser if the listener dislikes in-ear tips, needs a headphone jack, or wants a single-charge battery figure closer to Bose’s listed 20 hours.
• Best for adjustable noise cancellation → Bose Headphones 700. Bose specifies 11 levels; Sennheiser lists active noise cancellation but does not specify multiple levels.
• Best for a charging-case setup → Sennheiser Consumer Audio Momentum. Its case extends the stated total listening time up to 28 hours.
• Best for longer listening between charges → Bose Headphones 700. Bose lists up to 20 hours on one charge, compared with up to 7 hours for Sennheiser’s earbuds alone.
• Best for calls in noisy or windy conditions, based on the stated feature set → Bose Headphones 700. Its microphone system is described as adapting to those environments to pick up the voice.
• Best for compact, cable-free earbuds → Sennheiser Consumer Audio Momentum. Both earbuds are wireless, and the case is part of the package.
• Best for voice assistants from the headset → Bose Headphones 700. It offers Alexa and Google Assistant access; Sennheiser describes voice control with Google Assistant or Apple Siri.
• Best for a listener who wants audio to pause when removing an earbud → Sennheiser Consumer Audio Momentum. Smart Pause handles that automatically.
For a child, fit should come before a feature checklist. Bose is an over-ear product, but its listed age range is adult and the product details do not give child-specific measurements. Sennheiser is also described for adults, and its own guidance makes clear that tip fit can affect both sound and calls. If the child cannot wear the Sennheiser tips securely and comfortably, its noise cancellation and sound features are less useful in practice.
Think about where the headphones will be used. Bose’s adjustable cancellation, touch controls, voice-assistant access, microphone system, and included audio cable make it a flexible over-ear option for listening and calls. Sennheiser’s in-ear format, Smart Pause, charging case, and Transparent Hearing are more appealing to someone who wants small earbuds and a way to pause or bring in surrounding sound. The use case matters more than a generic claim that one format is better.
Battery figures also need a fair comparison. Bose gives a single wireless-battery figure of up to 20 hours. Sennheiser provides up to 7 hours for the earbuds and up to 28 hours when the case is included. If the listener can return the earbuds to the case between sessions, the total figure is relevant; for uninterrupted use away from the case, the standalone number is the one to consider.
Finally, neither set is presented as a child-specific headset. A parent choosing for a kid should check how each style sits, whether the controls seem manageable, and whether the listening routine makes more sense with a full-size headset or earbuds. If the choice is still close, check the current price on Amazon before deciding; I would not treat a price difference as a substitute for a proper fit.
I would choose Bose Headphones 700 for a kid if the child is comfortable with an over-ear fit and the priority is adjustable noise cancellation, straightforward headset controls, and a longer stated battery life per charge. Its adult age-range description means I would still check fit carefully.
Sennheiser is the better match for someone who specifically wants true wireless earbuds and values a charging case, Smart Pause, and in-ear noise cancellation. For my overall pick in this comparison, I lean Bose because its over-ear format avoids the tip-fit issue that Sennheiser explicitly calls out.
Neither product is described as child-specific; both list an adult age range. Bose is over-ear, while Sennheiser uses in-ear tips, so the better fit depends on the child’s comfort and preference.
Sennheiser lists up to 7 hours from the earbuds and up to 28 hours total with the charging case. Bose lists up to 20 hours on one wireless charge, so the figures describe different listening setups.
Bose specifies 11 active-noise-cancellation levels. Sennheiser also has active noise cancellation, combined with passive isolation from the in-ear fit, but its listed features do not state multiple cancellation levels.
Bose emphasizes a microphone system intended to adapt to noisy and windy environments and isolate the speaker’s voice. Sennheiser supports calls through its touch controls and voice features, but it notes that a poor ear-tip fit can affect call performance.

Who should skip it: Skip Bose if the listener strongly prefers earbuds, wants a compact in-ear set, or needs a product described specifically for children.
Sennheiser is the more compact choice for someone who prefers true wireless earbuds. The Momentum True Wireless 2 has rounded in-ear tips, a charging case, and no headphone jack. Bluetooth 5.1 and a listed range of 10 meters describe its wireless connection.

Sound features are a major part of its appeal. Sennheiser specifies 7-millimeter dynamic drivers and a frequency range of 5 to 21,000 Hz.

Sennheiser’s in-ear format, Smart Pause, charging case, and Transparent Hearing suit someone who wants small earbuds and a way to pause audio or bring surrounding sound into the listening experience. The right choice is the one that matches the listener’s habits, not an abstract claim that one format is always better.
Battery figures also need a fair comparison. Bose gives a single wireless-battery figure of up to 20 hours. Sennheiser gives up to 7 hours for the earbuds and up to 28 hours when the case is included. If the listener can return the earbuds to the case between sessions, the combined figure is useful. For uninterrupted listening away from the case, the standalone battery figure is the one to consider.
