The Best Cheap Wireless Earbuds (Under $40) on Amazon in 2018

Truly wireless earbuds like Apple's AirPods are expensive, but there are cheaper options available. Some earbuds connect wirelessly to a phone, but the earbuds themselves are attached with a cable. 

These tethered earbuds have longer battery life than truly wireless models. They're harder to lose and almost every model is either IPX6 water-resistant or IPX7 waterproof. The tradeoff is that the earbuds can tug on each other while running or exercising.

Cheap wireless earbuds are a worthwhile purchase (you can score a decent pair for less than $20). It's ironic, but I've seen people buy cords for their AirPods because they're afraid of losing them. Why pay $150 for truly wireless earbuds if you're going to put a cable on them! It doesn’t make sense.

Here are the best-reviewed “tethered” wireless earbuds selling on Amazon for $40 or less:

Mpow Flame Bluetooth Headphones Waterproof IPX7, Wireless Earbuds Sport, Richer Bass HiFi Stereo In-Ear Earphones w/ Mic, Case, 7-9 Hrs Playback Noise Cancelling Headsets (Comfy & Fast Pairing)

Avg. Price: $20 | Bargain Price: $17

Mpow's waterproof Bluetooth headphones pair well and sound good for the money, according to several Amazon customers. Those same customers warn that people with small ears should avoid these earbuds, especially for workouts, because they feel like they might fall off.

SENSO Bluetooth Headphones, Best Wireless Sports Earphones w/Mic IPX7 Waterproof HD Stereo Sweatproof Earbuds for Gym Running Workout 8 Hour Battery Noise Cancelling Headsets

Avg. Price: $28 | Bargain Price: $10

Senso's Bluetooth earbuds are lightweight and comfortable, according to several Amazon customers who praised the earbuds vocal clarity (but some criticized the weak bass). These earbuds mostly stay secure during workouts, but runners said to expect some wind noise while sprinting.

Mpow D7 [Upgraded] Bluetooth Headphones, IPX7 Waterproof Richer Bass Stereo Wireless Sports Earbuds w/Mic, 10~12H Battery Noise Cancelling Earphones for Running, Jogging, Cycling, Exercising, Workout

Avg. Price: $23 | Bargain Price: $20

More than 82% of Amazon customers like or love these Mpow Bluetooth earbuds. Several customers describe the battery life as excellent. These earbuds require some tinkering with the included tips and inserts to be truly comfortable. Some reviewers wish these earbuds looked sleeker and less bulky.

TaoTronics Bluetooth Headphones, Sweatproof Wireless in Ear Earbuds, Sports Magnetic Earphones with Built in Mic (IPX6 Waterproof, aptX Stereo, 8 Hours Playtime, CVC 6.0 Noise Cancelling Microphone)

Avg. Price: $36 | Bargain Price: $30

TaoTronics Bluetooth earbuds have great sound quality and are good for workouts, but several customers found these earbuds disappointing for making phone calls. These earbuds don't get very loud (for better or for worse), according to several customers.
