Built-in microphone/control module. If you’re not fond of pulling your phone out of your pocket, some headphones have control modules and mics on the wire or built into the headphones that let you do a number of things. You can answer phone calls, access Siri or Google Now, and control your music. Always check what the controls are and see if they match your preferences.

Anker is known more for its value headphones, but it's trying to step into more premium territory with its Soundcore Liberty 2 Pro earbuds, which carry a list price of $150. From a design standpoint, they share some similarities with Sony's WF-1000XM3, although this model doesn't have active noise-cancellation. Anker says they have large 11mm drivers combined with Knowles Balanced Armature, with up to 8 hours of battery life on a single charge (32 total hours of playtime with the case) and noise-cancellation microphones to help reduce ambient sound so callers can hear you better. They charge via USB-C and also support wireless charging.
Frequency response: Frequency-response specifications in full-size loudspeakers are generally pretty useless in predicting sound quality, but headphone frequency-response numbers are even worse. Manufacturers have routinely exaggerated frequency-response figures to the point that they're irrelevant. Even the flimsiest, cheap headphones routinely boast extremely low bass-response performance --15Hz or 20Hz -- but almost always sound lightweight and bright. Generally, bass buffs will be happier sticking with larger 'phones.
Although the Cambridge Audio Melomania 1 pair sounded good and came with a neat optional silicone carry sleeve for the charging case, we had difficulty getting the tips to seal, and the control buttons clicked loudly in our ears when we pressed them. The Melomania 1 also produced a noticeable latency delay that made watching videos on a device less enjoyable.

We use the term “home/studio-style” to describe the typically larger headphones that look like earmuffs, with two ear cups connected by an adjustable headband. Many are corded, with 3- to 8-foot wires—so they can be connected to an audio source such as a receiver or TV. Some fold for storage and come with carrying pouches. There are also battery-powered, wireless models—which use Bluetooth or other technology to connect to a smartphone and other devices without the cord.

Master & Dynamic fit a 10mm beryllium driver inside each of the earbuds to deliver audio that could rival 50mm over-ears. Active noise cancelation keeps the unwanted noise out, but there’s an ambient listening mode if you need it. And on the call side, voices are clear thanks to two microphone arrays that help eliminate background noise. By far the biggest reason for owning them, however, is the ten-hour battery life, which is well beyond the average mark. The stainless steel carrying case only adds an extra 12 hours, but who cares when you have that much in the tank?
Audio-Technica has announced two new sets of true wireless earbuds: the Audio-Technica ATH-CK3TW and the Audio-Technica ATH-CKS5TW. The CK3TW offers six hours of battery life per charge, with an additional 24 hours of juice in the case, and is expected to be priced at $100. The CKS5TW promises 15 hours of battery life per full charge, with an additional 30 hours in the charging case, and features aptX, SBC, and AAC compatibility; that pair costs $170.
The Monoprice True Wireless Plus Earphones (38542) are fine but a bit overpriced for what they give you. We found that the controls caused the earbuds to push into our ears a bit, which made the multi-click controls annoying to use. Male vocals got somewhat veiled by the bloated bass, and high frequencies had a shushing quality rather than crispness, but the effect was not the worst we’d heard. Overall, this pair isn’t bad, but we’d like to see it cost under $50.
Surprisingly, many of these wire-free models can be used at the gym and even get wet, despite the fact that each earpiece has an exposed charging contact on the inside. Check the IP rating of these; some workout-friendly earphones are only IPX4-rated, so they can stand up to sweat but might be hard to wash. Others are IPX7-rated, which means they can survive getting rinsed and dunked.
Master & Dynamic MW07 Go: This pair offers a lot of positives. The earbuds are very comfortable and stable in the ears, and we like the separate volume and track controls, although the volume buttons are a tad small for those with larger fingers. The 10-hour battery life and 30-meter Bluetooth range are impressive for this category. The small fabric-wrapped case and the earbuds themselves feel well made. However, although the sound was rather good in our tests, the bass was boosted in a way that could veil male vocals on bass-heavy songs. And we wished the Go had a transparency mode so we didn’t need to take these earbuds out to have a conversation. But if those aren’t dealbreakers for you and you aren’t turned off by the $200 price, they’re solid earbuds.
The treble and the mid-range performance sets the best wireless earbuds apart from their rivals. It will help you enjoy the vocals, as well as the finer details in a song's instrumental accompaniment to the fullest. Bass is typically the easiest audio bit to reproduce. But, especially in affordably-priced headsets, it might come at the expense of the mids and the highs.
They are a very good looking set of headphones that are available to buy in a few different colour options. They looks so good because the have a tapered look to them meaning they don’t sit to far from the head despite the large pads. The pads by the way are fantastic, extremely comfortably for long listening sessions and they leave a lot of air inside the cup that helps dissipate heat build up.
Technically speaking, earbuds are not earphones, as they don't enter your ear canal. Instead they sit just outside of it, where it's easy to become loose and cause problems when it comes to accurate stereo imaging (in which both ears get the same amount of audio) and bass response. Earphones, meanwhile, fit in the ear canal and form a seal inside your ear, blocking outside noise while piping sound directly into your ears. They're much smaller and lighter than headphones, since they don't need to fit on or over your ears and don't require any outside support (though some have stiff wire sections or flexible fins to keep them in place without getting in the way). Plus they won't mess up your hair.
