JBL Vibe Beam vs Sudio B2 at a Glance
• JBL Vibe Beam: 8 mm drivers, a closed in-ear fit, and JBL Deep Bass Sound make it the more straightforward choice for bass-led playlists. The trade-off is that its closed design is meant to keep outside sound out.
• Sudio B2: Open-ear bone conduction leaves the ears uncovered and is designed for people who want to remain aware of their surroundings. The trade-off is a shorter stated listening time than the JBL earbuds and a different sound presentation.
• Battery: JBL lists up to 8 hours in the earbuds and 24 more in the case, for up to 32 hours total. Sudio lists up to 7.5 hours at 50% volume.
• Weather protection: JBL lists IP54 for the earbuds and IPX2 for the case; Sudio lists IPX5 water resistance for the headphones.
• Choose JBL if you want sealed earbuds, emphasized bass, and a case that adds listening time between charges. Choose Sudio if open ears and a lightweight, flexible fit matter more than sealed-in sound.
The JBL Vibe Beam is a conventional true wireless earbud, with an in-ear, stick-closed design and 8 mm dynamic drivers. JBL describes its audio as Deep Bass Sound, so it makes sense for someone who likes a fuller, bass-forward feel in music. Its closed fit is also intended to exclude external sounds, which can make a gym playlist feel more self-contained. That same isolation is a trade-off: these are not the pick for someone who wants their ears uncovered while moving around.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Battery life is a practical strength on paper. JBL lists up to 8 hours from the earbuds and another 24 hours from the charging case, with a total of up to 32 hours. If the earbuds need a quick boost, a 10-minute charge is listed as adding two hours of listening. That combination suits a person who wants to charge less often or might forget to top up before heading out.
For gym use, the earbuds have an IP54 rating for water and dust resistance, while the charging case is rated IPX2. JBL also lists Bluetooth 5.2, hands-free stereo calls with VoiceAware, and a 10-meter Bluetooth range. I would choose these for someone who wants sealed, bass-oriented earbuds and long combined battery life. I would skip them if the main need is open-ear awareness or a clip-on style: the Vibe Beam is an in-ear design, not a clip-on or bone-conduction headset.
The Sudio B2 is built around a different priority: leaving the ears open. Its bone-conduction technology is designed to send sound through the temples rather than sealing an earbud into the ear. The design is aimed at active listeners who prefer to keep their ears free and remain more aware of their surroundings. That can be a useful distinction for outdoor movement or for gym sessions where hearing the environment is important to the wearer.
Sudio lists the B2 at 29 g, with a band designed to sit around the head. It has physical buttons near the ears for playback and other functions. The open-ear approach also changes what to expect from the sound: Sudio describes it as airy and transparent, while JBL emphasizes bass through a closed in-ear fit. Neither description makes one format universally right. They point to different listening priorities.
The B2 offers up to 7.5 hours of playtime at 50% volume and has a stated USB-C charging time of 1.5 hours. It uses Bluetooth 5.3, has omnidirectional microphones, and carries an IPX5 water-resistance rating. I would consider it for someone who values awareness, a light band-style fit, and open-ear listening during exercise. I would skip it if I wanted the more sealed, bass-led experience of ordinary earbuds, or if having a charging case provide additional listening time is central to my routine. The provided specifications do not list a charging case for the B2.
• Best for a bass-forward, sealed listening experience → JBL Vibe Beam. Its 8 mm drivers and closed in-ear design are the clear match for someone who wants music to feel more insulated from the room.
• Best for keeping your ears uncovered → Sudio B2. Bone conduction and its open-ear design are intended for listeners who want more awareness of their surroundings.
• Best for stated total battery time → JBL Vibe Beam. JBL lists up to 32 hours combined: 8 hours in the earbuds and 24 hours in the case. Sudio lists up to 7.5 hours at 50% volume.
• Best for a quick charging boost → JBL Vibe Beam. Its listed 10-minute speed charge provides two additional hours of listening. Sudio’s listed charging time is 1.5 hours, with no comparable quick-boost figure provided.
• Best for a band-style fit during movement → Sudio B2. Its flexible band is designed to sit around the head, while JBL uses separate in-ear earbuds.
• Best for the higher listed headphone water-resistance rating → Sudio B2. It is rated IPX5. JBL’s earbuds are IP54, and its charging case is IPX2. These ratings describe different protection categories, so the distinction is not a complete one-to-one comparison.
• Best for gym listening that prioritizes isolation and bass → JBL Vibe Beam. The closed design and bass-focused audio description line up with that preference.
• Best for a gym session where awareness matters → Sudio B2. The open-ear design is its defining advantage; it is not a sealed earbud substitute.
A note on search terms: people looking for multipoint true wireless earbuds for gym, the best bluetooth headset for gym, or clip on earbuds for gym are describing different needs. The supplied specifications do not list multipoint connectivity for either product, and neither is described as a clip-on model. JBL is the true wireless in-ear option here; Sudio is the open-ear, band-style option. I would not assume either offers a feature that is not specified.
I would buy the JBL Vibe Beam for a gym routine built around music, bass, and fewer charging interruptions. Its closed in-ear design, up to 32 hours with the case, and listed quick charge make a persuasive combination for that use. The Sudio B2 is the better fit if keeping the ears uncovered is the deciding factor. For my gym recommendation, though, I would pick JBL because its sound and battery setup better match a focused, music-first workout.
FAQ
Are JBL Vibe Beam or Sudio B2 better for the gym?
It depends on what matters most in the workout. JBL is the more direct match for sealed, bass-focused listening and lists up to 32 hours total with its case. Sudio is designed for open-ear listening and greater awareness of surroundings.
JBL lists up to 8 hours from the earbuds and 24 additional hours from the case, for up to 32 hours total. Sudio lists up to 7.5 hours at 50% volume. Those figures are presented differently, so they are not a direct test under identical conditions.
Multipoint connectivity is not listed in the provided product specifications for either model. JBL lists Bluetooth 5.2, and Sudio lists Bluetooth 5.3, but a Bluetooth version alone does not establish multipoint support.
Sudio lists an IPX5 rating for the B2. JBL lists IP54 for the Vibe Beam earbuds and IPX2 for the charging case. The ratings use different protection categories, so compare the earbuds and case separately rather than treating them as identical measures.
