• Anker Soundcore Space One's biggest strength: adaptive active noise cancelling with five adjustable levels in the app, plus 40 hours of playtime with ANC on and 55 hours with it off.
• Anker Soundcore Space One's biggest trade-off: it's a wireless Bluetooth headphone first — if you already own high-end wired headphones and want them to sound their best, it doesn't do that job.
• Khadas Tea Pro Magnetic's biggest strength: a credit-card-sized DAC/amp with an ES9039Q2M chip, PCM 768kHz/32-bit and DSD512 decoding, 3.5mm and 4.4mm outputs, and a magnetic back that snaps onto MagSafe iPhones.
• Khadas Tea Pro Magnetic's biggest trade-off: it makes no sound on its own. You need your own wired headphones, and its magnetic mounting is built around iPhone 12–17, not every phone.
• Who Anker Soundcore Space One is for: commuters, travelers and everyday listeners who want one self-contained wireless headphone.
• Who Khadas Tea Pro Magnetic is for: wired-headphone owners who want better sound out of their phone and don't mind carrying a small extra device.
The Space One is a complete listening device. You put it on, pair it over Bluetooth 5.3, and you're done. The adaptive noise cancelling auto-calibrates to what's around you and to how the headphones are actually sitting on your head — a genuinely useful detail, because ANC falls apart when a headphone breaks its seal. It's tuned to fight the low, continuous sounds that dominate real commutes: engine rumble, air-conditioning hum, the drone of a train. With five ANC levels in the soundcore app, you can dial the cancellation up on a plane and back down when you still want to hear the world.
The audio side is built around 40mm dynamic drivers with LDAC support for Hi-Res wireless listening, and the frequency range runs a standard 20–20000 Hz at 16 ohms. Battery life is the headline spec for most buyers: 40 hours with ANC on, 55 hours with ANC off. That's a headphone you charge once and forget about for a week of commuting.
Who should buy it: anyone who wants one pair of wireless over-ears for commuting, travel, office work and casual listening, and who values long battery life over audiophile decoding. Who should skip it: listeners who already own a good wired headphone and are chasing the last bit of sound quality from a phone — that's not what this product is for.
Khadas Tea Pro Magnetic: Who It's For
The Tea Pro is a different category entirely, and that's the whole point of comparing these two. It's a portable DAC and headphone amplifier — the box that sits between your phone and your wired headphones and does the digital-to-analog conversion plus amplification. It weighs 96 grams, measures just 7.85mm thick, and is roughly the size of a credit card. Inside is an ES9039Q2M DAC chip decoding up to PCM 768kHz/32-bit and DSD512. For anyone who has spent time with high-resolution audio files, those numbers are the reason to care.
The outputs tell the same story. You get both a 3.5mm single-ended output and a 4.4mm balanced output — the latter being the connector that serious in-ear and over-ear owners tend to want, since balanced drive typically means more headroom for harder-to-drive headphones. It connects over USB or Bluetooth 5.4, runs on a 2100mAh battery, and has a 0.95-inch AMOLED display that shows playback information so you're not guessing what's happening.
The "Magnetic" in the name is the design hook. Strong magnets hold the Tea Pro onto iPhone 12–17 bodies, so it rides on the back of your phone instead of dangling from a cable. The back is finished in wear-resistant leather to resist scratches and stains and to avoid the scraping you get from bare metal-on-metal contact. It's a considered piece of industrial design for people who take mobile audio seriously.
Who should buy it: wired-headphone owners who want their phone to drive those headphones properly, who care about hi-res decoding and a balanced output, and who like the idea of the amp snapping onto the back of an iPhone. Who should skip it: anyone who wants a single self-contained wireless headphone, anyone without wired headphones to plug in, and anyone who wants noise cancelling — the Tea Pro has none, because it isn't a headphone.
Side-by-Side: Which Should You Choose?
• Best for long battery life → Anker Soundcore Space One. 40 hours with ANC on, 55 hours with it off, versus a 2100mAh battery powering a small amp.
• Best for hi-res wired listening → Khadas Tea Pro Magnetic. PCM 768kHz/32-bit and DSD512 decoding via an ES9039Q2M, with 3.5mm and 4.4mm outputs.
• Best for travel convenience → Anker Soundcore Space One. One device, wireless, with a 3.5mm jack for in-flight systems and a carry pouch included.
• Best for phone-based portable audio → Khadas Tea Pro Magnetic. Credit-card footprint, 96g, 7.85mm thin, snapping magnetically to iPhone 12–17.
• Best for calls and voice pickup → Anker Soundcore Space One. Three mics with AI-assisted voice reduction; the Tea Pro is a listening device, not a headset.
• Best for owners of good wired headphones → Khadas Tea Pro Magnetic. It exists to make the headphones you already own sound better on the move.
• Best for a single do-everything purchase → Anker Soundcore Space One. If you own nothing yet, this is the one that plays music the moment you unbox it.
For most people reading this, I'd buy the Anker Soundcore Space One. It's the product that works out of the box for commuting, flights, calls and all-day listening, and the 40-hour ANC battery figure is the kind of spec that quietly solves a real annoyance. The Tea Pro is the more interesting device, but it's a specialist tool: it only makes sense if you already own wired headphones worth driving and you want a pocket-sized amp. In my opinion, buy the Space One if you need a headphone; buy the Tea Pro if you need to upgrade the one you already have.
FAQ
No. It has no speakers or drivers of its own. It decodes and amplifies audio for headphones you plug into its 3.5mm or 4.4mm output, so you need your own wired pair to hear anything.
It connects over USB and Bluetooth 5.4, so it works with a range of sources. The magnetic mounting, however, is described as compatible with iPhone 12–17, so Android users would be relying on the cable rather than the magnet.
They answer that question differently. The Space One gives you LDAC Hi-Res wireless audio from 40mm dynamic drivers in a wireless headphone. The Tea Pro gives you PCM 768kHz/32-bit and DSD512 decoding through a dedicated DAC chip — better on paper for high-resolution files, but only with wired headphones attached.
