If you want active noise cancelling with a secure, wingtip-stabilised in-ear fit and deep Apple ecosystem integration, choose Amazon Renewed Beats Fit Pro; if you need open-ear bone conduction so you stay aware of traffic and your surroundings while training, choose Sudio B2.
• Amazon Renewed Beats Fit Pro — biggest strength: Active Noise Cancelling plus Transparency Mode, Spatial Audio with dynamic head tracking, and the Apple H1 chip for Automatic Switching, Audio Sharing and "Hey Siri".
• Amazon Renewed Beats Fit Pro — biggest trade-off: In-ear silicone tips physically seal your ear canal, so you are cut off from your environment when ANC is on, and rated battery life is about 6 hours per charge.
• Sudio B2 — biggest strength: Bone conduction drivers sit outside your ear, so your ear canal stays open and you hear traffic, teammates and announcements while you listen.
• Sudio B2 — biggest trade-off: Open-ear sound leaks both ways — no noise cancelling at all, and the spec sheet lists no noise control feature.
• Pick Amazon Renewed Beats Fit Pro if you want noise cancelling, immersive spatial audio and tight iOS/Android app control.
• Pick Sudio B2 if you want a light 29 g open-ear band for cycling, running or commuting where awareness matters more than isolation.
The Beats Fit Pro is a true wireless in-ear design, and the detail that defines it is the flexible wingtip. Wingtips hook into the ridge of your ear rather than relying on the tip alone, which is exactly the kind of stability you want when you are moving — gym sessions, runs, commutes where you are pulling a bag over your head. The silicone enclosure and rounded tips are built around that secure seal, which is also what makes noise cancelling possible in the first place.
Feature-wise, this is a two-mode earbud. Active Noise Cancelling shuts the world out; Transparency Mode lets it back in without removing the buds. On top of that you get Spatial Audio with dynamic head tracking, which is the standout for anyone watching movies or playing games on a phone or tablet — the soundstage tracks your head movement rather than sitting flat. The Apple H1 chip adds Automatic Switching between Apple devices, Audio Sharing with another pair of Beats or AirPods, and "Hey Siri" voice control. Android users are not locked out either: the Beats app covers the equivalent controls on that side.
Who should buy it? In my opinion, this is the pick for someone who wants one pair of earbuds for noisy environments — flights, trains, open-plan offices, loud gyms — and who values an immersive, head-tracked spatial presentation. Who should skip it? Anyone who needs to hear their surroundings while they train, and anyone who dislikes the plugged-ear feeling of silicone tips. Note also that this is a Renewed unit backed by a 90-day limited warranty rather than a new retail box, so factor that into your expectations.
The Sudio B2 is a completely different animal: an open-ear bone conduction headphone built around a band that wraps your head. Instead of pushing sound into your ear canal, bone conduction drivers transmit through your temples, leaving your ears physically open. That single design choice explains everything else about it — the awareness, the fit philosophy, and the sound profile.
The band uses what Sudio calls "lagom tension" — Swedish for just the right amount — so it sits around your head without clamping. At 29 g it is genuinely light, and the open-ear placement means no pressure inside the ear at all, which matters on long rides or extended wear. You get Bluetooth 5.3 with a 10-metre range, an IPX5 splashproof rating for rain and sweat, and up to 7.5 hours of playtime at 50% volume with a 1.5-hour USB-C charge. Controls are physical buttons: play/pause in front of the ear, secondary functions behind it — a deliberate choice over touch, and easier to hit with wet or gloved hands.
Sound is described as airy and transparent with a 20Hz–20kHz range and 83.5 dB sensitivity, and Dirac Virtuo spatial processing is on board. Be realistic here: bone conduction is not going to deliver the bass slam or isolation of a sealed in-ear bud, and with no noise cancelling, loud environments will compete with your music. Who should buy it? Cyclists, runners, gym-goers and commuters who prioritise hearing traffic and staying aware. Who should skip it? Anyone who wants to block out a noisy office or aeroplane cabin — this is the wrong tool for that job.
• Best for noise cancelling → Amazon Renewed Beats Fit Pro. It is the only one of the two with Active Noise Cancelling, plus a Transparency Mode when you want the opposite.
• Best for staying aware of your surroundings → Sudio B2. Open-ear bone conduction means your ear canal is never blocked.
• Best for immersive movie and game audio → Amazon Renewed Beats Fit Pro. Spatial Audio with dynamic head tracking is a headline feature here; the Sudio B2 offers Dirac Virtuo spatial sound but without head tracking.
• Best for battery life → Sudio B2. Up to 7.5 hours at 50% volume versus roughly 6 hours on the Beats.
• Best for Apple ecosystem users → Amazon Renewed Beats Fit Pro. The H1 chip gives Automatic Switching, Audio Sharing and "Hey Siri".
• Best for secure, high-motion fit → Amazon Renewed Beats Fit Pro. Flexible wingtips are designed specifically to lock the bud in place.
• Best for all-day light wear and sweat/rain → Sudio B2. 29 g on the head plus IPX5 splash resistance; the Beats Fit Pro sheet does not list a water-resistance rating.
• Best for physical, gloved-hand controls → Sudio B2. Button controls rather than the Beats' touch and voice-driven control set.
I would buy the Amazon Renewed Beats Fit Pro. The reason is simple: noise cancelling, spatial audio with head tracking and the Apple H1 feature set are three things nothing on the Sudio B2 spec sheet can match, and the secure wingtip fit makes it the more versatile everyday earbud for noisy environments. The Sudio B2 is the better answer only if your priority is hearing the world around you — cycling, running, busy streets. If that is your life, the B2's open-ear design and 7.5-hour battery make it the smarter buy. If you want to weigh the current numbers yourself, check the latest price on Amazon before deciding.
A Renewed unit is a pre-owned item that has been inspected and supplied with the listed accessories, and it carries a 90-day limited warranty. If you are comfortable with that instead of a sealed retail box, it can be an economical route to the same model.
No. The spec sheet lists noise control as none, and the open-ear bone conduction design deliberately leaves your ear canal unblocked. They reduce nothing — that is the trade-off you accept for environmental awareness.
The Sudio B2 is rated for up to 7.5 hours at 50% volume, while the Beats Fit Pro is rated at about 6 hours. The Beats ships with a pocketable charging case, which extends total listening time between wall charges.
Yes. The Beats app for Android provides access to the controls and features, while iOS users get the deeper Apple H1 integration such as Automatic Switching and Audio Sharing. Either way, the core comfort and fit design is the same.
