Space A40, Ear (a), and More Tested

Flagship earbuds like Apple’s AirPods Pro, Sony’s WF‑1000XM5, Jabra’s Elite 10, and Soundcore’s Liberty 4 Pro sound fantastic, but they come with equally premium price tags. Luckily, there are plenty of stellar alternatives that won’t gut your wallet. Spend less than $100, and you can still land punchy audio, rock‑solid active noise canceling (ANC), and marathon battery life without feeling like you settled.

Below, we start with our overall winner and count down to number five, covering specs, pros and cons, and the exclusive, standout features that separate each pair from the pack. Each model stands out for different strengths, so you can zero in on the perfect balance of price and performance without sacrificing the features that matter most to you.

Whether soaking up the atmospheric synths in Hans Zimmer’s latest score or streaming lossless jazz tracks, the Space A40 constantly surprises with a soundstage that feels far wider and cleaner than any sub‑$50 earbuds have a right to. Their feather‑light shells vanish in the ear, while adaptive ANC hushes train rattle to a whisper and LDAC (Lossless Digital Audio Codec) unlocks hi‑res clarity that lets cymbals shimmer and bass lines stay tight. Top it off with a Qi‑ready case good for a ridiculous 50 hours of total playtime, and you’ve got the most complete bargain in personal audio — the reason these are our runaway #1.

Dual‑driver buds for under forty bucks used to be pipe dreams, yet CMF pulls it off on its Buds Pro 2 with an 11 mm woofer and 6 mm tweeter that sling punchy, disciplined bass under sparkling highs. Flip on the hybrid ANC, and the commute clamor fades. Or crank Ultra Bass Tech 2.0 when you want club vibes on the go.

Give the Air Pro 4 to any spec‑sheet junkie and watch their jaw drop: Snapdragon Sound with aptX Lossless, Bluetooth 5.4 ready for Auracast broadcasts, and adaptive hybrid ANC that lops off 50 dB of airplane hum. In practice, that means you can stream bit‑perfect 24‑bit/96 kHz files over aptX Lossless and still have battery to spare after an 11‑hour work session. The tuning skews neutral‑bright, so vocals pop and strings retain air, yet the 10 mm driver digs deep when the bass hits. If you crave tweakability, EarFun’s app offers 10‑band EQ and gesture remapping that puts pricier brands to shame.
