How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a simple, no-case set of earbuds with magnetic auto power, long single-charge playback and a full kit of ear tips and hooks, choose Crave Octane; if you need a lipstick-style design with a charging case, a digital display, Bluetooth 5.3 and active noise cancellation, choose SUNOL E50.
• Crave Octane — biggest strength: 8 hours of playback on a single charge plus magnetic ends that power the buds on and off automatically when you snap them together.
• Crave Octane — biggest trade-off: No charging case in the box, no active noise cancellation, and the battery figure is listed the same for charge time and average life, which is worth a second look.
• SUNOL E50 — biggest strength: A charging case rated for 72 hours of stored power, a fast 40-minute top-up, Bluetooth 5.3 and active noise cancellation.
• SUNOL E50 — biggest trade-off: Shorter single-charge life at 6 hours, and the listed frequency response is a narrow 1 KHz band, which tells you little about real music range.
• Pick Crave Octane if you want one pair of buds, one cable, no case to remember, and controls that respond to touch during runs and commutes.
• Pick SUNOL E50 if you want the case-and-carry experience, a display to check on power, and a smaller, more discreet fit.
The Crave Octane is an in-ear wireless Bluetooth set with a 10-meter range and a design built around movement. The headline feature is the magnetic ends: connect them and the earbuds power down, pull them apart and they switch back on. That sounds like a small thing, but it removes the two habits that kill earbud batteries — leaving them running in a pocket and forgetting to switch them off. You just clip them together.
The second anchor is the battery figure. Crave lists up to 8 hours of playback, and that number covers both listening and talking thanks to the in-line microphone. There is no case involved, so that 8 hours is what you get from the buds themselves before you reach for the included USB cable. For a commute, a gym session and a workday of calls, that is a workable single-charge window.
Who should skip it? Anyone who wants active noise cancellation — Crave lists noise control as "None," so these are passive-fit buds, not noise-cancelling ones. Anyone who wants a charging case to top up on the go should look elsewhere. And if you prefer a discreet, low-profile look, the Octane reads as a conventional sport earbud rather than a fashion piece. I'd point this at runners, cyclists and gym-goers who want a single set they can keep in a bag with a pouch and cable, and forget about the rest.
SUNOL E50: Who It's For
The SUNOL E50 takes the opposite approach: it is a system, not just a pair of buds. The earbuds sit in a lipstick-style charging case in blue, made from ABS, and that case is rated for 72 hours of stored power. SUNOL frames the whole thing as roughly 3 days of play time with the case factored in. The buds themselves give 6 hours at 100% volume and 6 hours of talk time, and they recharge in about 40 minutes in the case.
The case also carries a digital display, which is the practical payoff of the lipstick design — you can see the power state rather than guessing. Connectivity is Bluetooth 5.3 with EDR, rated for the same 10 meters (about 33 feet) as the Crave, and it is described as compatible with any Bluetooth-enabled phone or tablet. Sensitivity is listed at 105 dB with a dynamic driver.
The E50 also lists active noise cancellation, which is the single biggest functional gap between these two. It has touch controls and a volume control function, plus a built-in HD microphone aimed at in-car calls, chatting, games and work use. The IPX4 rating matches the Crave, so sweat and light rain are covered on both sides.
I'd recommend the E50 for someone who wants a case-based routine — drop the buds in, check the display, carry them in a pocket or small bag — and who values noise cancellation and a compact, low-profile look over maximum single-charge runtime.
Side-by-Side: Which Should You Choose?
• Longest single charge → Crave Octane. 8 hours on the buds versus 6 hours on the E50.
• Longest total play time → SUNOL E50. The case adds up to 72 hours of stored power.
• Fastest recharge → SUNOL E50. 40 minutes in the case versus an 8-hour charge time listed for the Octane.
• Noise cancellation → SUNOL E50. Active Noise Cancellation is listed; Crave lists noise control as None.
• Auto power management → Crave Octane. The magnetic ends switch the buds off and on without any button press.
• Newest Bluetooth standard → SUNOL E50. Bluetooth 5.3 with EDR versus the Octane's listed Bluetooth with a 10-meter range.
• Best fit kit for sport → Crave Octane. Three tip sizes, three hook sizes, a pouch and a cable in the box.
• Most discreet, case-first design → SUNOL E50. The lipstick-style case with a digital display is built for carrying, not for a gym bag pocket.
• Best for calls on the move → both, with a caveat. Both list a built-in microphone; the Octane's is in-line, the E50's is a built-in HD mic.
My Verdict
Both are IPX4, so sweat and splashes are covered either way. The Crave Octane has the edge because it includes three sizes of ear hooks and three sizes of tips, while the E50's listed accessories are a cable and charging station.
Yes — Active Noise Cancellation is listed for the E50. The Crave Octane lists noise control as None, so it relies on the in-ear seal rather than active cancellation.
The Crave Octane is rated up to 8 hours of playback and talk on a single charge. The SUNOL E50 is rated 6 hours per charge, with the case adding up to 72 hours of stored power.
The Crave Octane. It ships with a storage pouch and a USB charging cable rather than a charging case, and the magnetic ends shut the buds down when you clip them together. If you want a case with a digital display, go with the E50 instead — and check the current price on Amazon before you decide.
