Which model this is

This page covers the Baseus Eli 2i Fit open-ear true wireless earbuds, model “Baseus Eli 2i Fit”, sold in Black and White. Identifiers: ASIN B0FS6BVS2X, UPC 810196183650, EAN 081019618365, Baseus SKU A0102604. Do not confuse it with the Baseus Eli 10i Fit, Eli Fit, Eli Sport 1/2, or other Baseus open-ear models. At least one AliExpress listing shares the name but quotes IPX7 and 4-mic noise reduction, which conflicts with the official IPX5 and 2-mic specification and may be a different variant.

Battery life and spec claims

The official page markets “36-Hour Power” while the specification table states 12 hours per charge and 40 hours with the case. These figures describe different scopes, and the spec table is the authoritative source. AliExpress listings for the same model name claim IPX7 water resistance and 4-mic noise reduction on at least one listing, against the official IPX5 and 2-mic specification. Treat the official specification as authoritative; the AliExpress listing may be a different variant. No per-earbud or case dimensions are published on the official product page.

Sound, calls and comfort

The official specification lists a 14.2 mm dynamic driver, 20 Hz - 20 kHz frequency response, SBC and AAC codecs, and 60 ms low latency. The 2-mic AI ENC system handles calls. Features include BassUp (Bass Boost), anti-sound-leakage and directional sound. Marketing copy describes 8.8 g per earbud and a zero-pressure comfort design for secure fit during sports. No measured frequency response, microphone quality data, latency measurements or battery endurance tests were published by the sources read.

Buying, availability and warranty

Baseus listed the earbuds at $19.99 on its US site, but they were sold out at the time of check. AliExpress listings for the IPX5 variant were observed at $22.61 to $29.29, and a separate listing quoting IPX7 and 4-mic at $45.59. Baseus’s general warranty policy is 18-24 months for orders placed on or after January 1, 2024, with the period beginning on the day the product is received. The exact warranty length for this model is not specified per model. The US return policy allows a 7-day no-reason return and a 30-day return for manufacturing defects. No user-replaceable parts, repair channel or service documentation was found for this model, and replacement ear tips are not documented.

Is it worth it?

At roughly $12 to $20 the package is a reasonable budget sports open-ear bud, with Bluetooth 6.0, a 14.2 mm driver, 12 hours of playback per charge and IPX5. At the AliExpress-observed $22 to $29 it remains reasonable if the fit suits the buyer. Above roughly $30, the value case weakens because the higher water-resistance and microphone claims are not supported by the official specification. Sound quality, fit and battery endurance are unverified by independent tests.
