If you want fitness-tracking earbuds with adaptive noise cancellation for flights, choose Sennheiser Momentum Sport Sport; if you need a long-range transmitter that broadcasts audio to several pairs of earbuds or hearing aids, choose Avantree DG60. These two products share almost nothing except a wireless signal, which is exactly why this comparison matters. One is worn in your ears on a plane, the other plugs into your computer at home.
• Sennheiser Momentum Sport Sport — biggest strength: True wireless sport earbuds with adaptive ANC, a transparency mode, Polar-powered heart rate and body temperature sensors, and 24 hours of total playtime (6 in the buds plus 18.5 in the case).
• Sennheiser Momentum Sport Sport — biggest trade-off: They are earbuds, not a transmitter. They play audio for one person, and the sweat/splash rating is IP55, not a full waterproof claim.
• Avantree DG60 — biggest strength: A Qualcomm Bluetooth 5.4 USB transmitter with Auracast, LC3 and aptX-Adaptive that can broadcast to many hearing aids, headphones or speakers at once, with a range up to 50 meters in open space.
• Avantree DG60 — biggest trade-off: It makes no sound on its own. It needs a PC and a receiving device, it is not compatible with iPhones for the Auracast Assistant, and hearing aid support is limited to the models Avantree lists.
• Who each is for: The Sennheiser pair is for one person who wants music, ANC and workout data. The Avantree dongle is for someone who wants to send one audio stream to several listeners.
The Momentum Sport is built around movement. Sennheiser tunes these earbuds with a sport sound profile and what the spec sheet calls robust bass, so the low end stays present when you are running, lifting or just trying to drown out cabin noise. The adaptive ANC adjusts to your surroundings, and transparency mode lets you hear announcements or a training partner without pulling a bud out. For flights, that combination is the whole point: you get the kind of active noise cancelling Bluetooth earbuds people look for on long trips, plus the option to switch back to the outside world in one tap.
Battery is the quiet strength. You get 6 hours in the earbuds and 18.5 hours in the case for 24 hours total, and a 10-minute quick charge buys 45 minutes of playback. That quick charge is the number I would care about most on a travel day, because it covers the gap between a dead case and boarding. Bluetooth 5.2, a 20 Hz–20,000 Hz dynamic driver and 16 ohm impedance round out a fairly conventional but sensible wireless spec.
Who should buy them: runners, gym regulars and frequent flyers who want one pair for training and travel, and who value heart rate and temperature data. Who should skip them: anyone who wants to share audio with a seatmate, anyone who needs headband-style over-ear isolation, and anyone who wants a passive wired option, since there is no headphone jack. Also skip if you need a longer single-charge runtime than 6 hours before the case comes into play.
Avantree DG60: Who It's For
The DG60 Aura is a different category entirely. It is a USB Bluetooth adapter built on Qualcomm's Bluetooth 5.4 chip, and its headline trick is Auracast over LC3. Plug it into a PC and you can broadcast audio to multiple Auracast hearing aids, headphones or speakers at the same time. Avantree frames this around shared watching, group listening and public audio spaces, and that framing is accurate — this is a one-to-many audio device, not a personal listening device.
The range claim is the other big number: up to 50 meters, or roughly 164 feet, in open space. That is a meaningful jump over what a typical laptop Bluetooth radio manages, and it is the reason people buy this class of dongle in the first place. It also supports aptX-Adaptive and LC3 for low latency, which is what you want when audio and video need to stay in sync. Firmware is upgradeable through Avantree's official site, so the feature set is not frozen at purchase.
Who should buy it: PC users who want to stream one audio source to several listeners, households with a mix of hearing aids and headphones, and anyone frustrated by short wireless range or laggy audio on a computer. Who should skip it: iPhone-centric households relying on Auracast, anyone who wants a self-contained listening device, and anyone whose hearing aids are not on the compatibility list.
Side-by-Side: Which Should You Choose?
• Best for noise cancellation on a plane → Sennheiser Momentum Sport Sport. Adaptive ANC plus transparency mode is exactly what a flight needs.
• Best for fitness data → Sennheiser Momentum Sport Sport. Heart rate and body temperature tracking from in-ear sensors is the standout feature here.
• Best for total playtime → Sennheiser Momentum Sport Sport. 24 hours combined, with a 10-minute charge giving 45 minutes of playback.
• Best for shared listening → Avantree DG60. Auracast broadcasting to many devices at once is its entire purpose.
• Best for wireless range → Avantree DG60. Up to 50 meters in open space versus the normal reach of earbud Bluetooth.
• Best for low-latency PC audio → Avantree DG60. Qualcomm Bluetooth 5.4 with LC3 and aptX-Adaptive is built for sync.
• Best for portability → Sennheiser Momentum Sport Sport. Earbuds and a case versus a dongle that needs a host device.
• Best for setup simplicity → Sennheiser Momentum Sport Sport. Pair once and go; the DG60 asks you to check a compatibility list first.
My Verdict
aptX-Adaptive is a Qualcomm Bluetooth audio codec that adjusts between higher quality and lower latency depending on what you are doing. It is listed on the Avantree DG60, which uses it alongside Bluetooth 5.4 and LC3 for stable, low-latency PC audio. The Sennheiser Momentum Sport Sport spec sheet lists Bluetooth 5.2 without naming a codec.
Not for its Auracast features. Avantree states the Auracast Assistant path requires Galaxy S24/S23, Pixel 8/8 Pro or other Android 14+ phones, and it is listed as not compatible with iPhones. Classic Bluetooth headphone pairing is a separate matter.
No. The spec sheet lists the headphone jack as "No Jack" and the connectivity as wireless Bluetooth. Charging and audio both run wirelessly through the included case and cable.
You get 6 hours in the earbuds and 18.5 hours in the carrying case, for 24 hours total. A 10-minute quick charge provides 45 minutes of playback.
