The Anker SoundBuds Curve are good sports headphones with a long battery life and a decent sound. They are comfortable with a sturdy earhook design for training and exercising. They are compact enough to fit in your pockets, and they are decently well built, though the audio cable is slightly thinner than comparable wireless in-ears. Unfortunately, they do not block so much noise that they may not be the best headphone for noisy, noisy environments, and some may sound too bass heavy for some.


The Anker SoundBuds Curve have a neat design that looks much more premium than their price suggests. The earphones feel tight, durable and feel a bit more comfortable than typical in-ears. They also have an earhook design with extra stability fins that make them sturdy enough for the gym. Unfortunately, the tips tend to come from the ears from time to time, especially during strenuous workouts. They also have fairly thin cables that do not feel as durable as some of the wireless in-ear / ear headphones we’ve tested like the Bose SoundSport Wireless. On the other hand, they have a simple and straightforward control scheme and a portable case.


The anchor SoundBuds Curve is a neat sounding pair of closed in-ear headphones. They have a deep, powerful and consistent bass, a clear and neutral center, and a smooth and balanced treble. Their bass, however, is a bit overwhelming, which can be welcomed by the fans of the bass-heavy genres, and their middle class has too little emphasis on vocals and lead instruments. On the other hand, they have excellent imaging performance, but like most other in-ears, they do not have a big, speaker-like stage.


The Anker SoundBuds Curve only passively blocks ambient noise, which is not ideal for commuters and very noisy environments. The in-ear buds are not the best seal in the ear canal, which allows part of your environment to feed into your audio medium, unlike the other in-ears we tested. On the other hand, since they barely leak, you can mask some of the sound by playing your music at a higher volume without disturbing the environment.


The inline microphone is of subordinate quality. In quiet environments, the speech recorded or transmitted with this microphone sounds remarkably thin and rather muted and incomplete. However, it will still be understandable. In noisy environments, the SoundBuds Curve anchor will struggle to separate speech and background noise even in moderately loud situations, such as a busy street.

Active Features

The Anker SoundBuds Curve offer a decent battery life but poor power saving features and no app support for customization. They lasted up to 13 hours with a single charge, which should be enough for a day of moderate to heavy use. You also do not need to charge too long (1.5 hours). Unfortunately, due to the missing app, they are less customizable than other wireless in-ears like the Jaybird X3. They are also not automatically disabled when inactive as long as they are paired with your Bluetooth source, which is a bit disappointing.


The SoundBuds Curve are pure Bluetooth headphones without audio cable or base / dock. They are one of the best wireless earphones we have tested so far. They have a reasonable wireless range, but do not support the simultaneous coupling of multiple devices or NFC. On the other hand, they have a relatively low latency for a Bluetooth headset and even support aptX, but are still not the ideal headset for games or movies.


Mixed Usage

The Anker Soundbuds Curve are subtly versatile headphones that are best suited for sports thanks to their stable, compact and wireless design. They have a long battery life and a good workmanship, especially in terms of their price range. However, they do not feel as durable as some of the more expensive wireless in-ears we tested. They have a moderately balanced sound but a bit too much bass for more critical listeners and they do not block much noise for an in-ear, so they may not be the best headphone for noisy, noisy commuters. On the other hand, they are always easy to carry and should be sufficient for most applications.

Critical Listening

Decent for critical listening. They have a fairly balanced sound with an almost flat mid-range and a good treble, so they don’t sound as sharp as some of the other in-ears we’ve tested. Unfortunately, they pack a bit too much bass which overpowers the instruments and vocals in the mid-range, but fans of extra bass may find it pleasing. They also have small closed earbuds that cannot create an adequate soundstage. This means they won’t be the best headphones for more critical listeners but should sound good enough for most, especially if you like a little bass.


Above average for commuting. They are compact, comfortable and easy to carry to your person. Their low leakage performance can somewhat compensate for the poor noise isolation by playing your music at a higher volume. However, they do not block much noise and should not be the first choice for noisy, noisy commuters.


Good for the sport. The Anker SoundBuds Curve features a sturdy earhook design and comes with a range of stabilizer fins and multiple tip sizes for a secure and comfortable fit. They are very breathable, easy to use and portable enough to carry with you at any time. However, the buds occasionally slip out of the ears during strenuous exercises, depending on the quality of the fit and seal that you can achieve with the tips provided.
