Sony’s Waterproof Walkman is an all-in-one device that doesn’t need to be connected to a phone or other playback source; instead, it has 4GB of storage to hold your music, and you can load up songs and playlists on your PC via the included USB cable just like in ages past. Sure, 4GB might not sound like much space, but that adds up to about 1,000 to 2,000 tracks, depending on their file size. All playback is controlled with tiny buttons on the sides of each earbud. Speaking of charge, the W-Series Walkman will last up to 12 hours per charge, and Sony claims you’ll be able to charge them in no time via their quick-charge feature.
We could have gone many ways for this pick, but 1More’s unassuming Triple Drivers just wouldn’t stop popping up into the picture. The 1More in-ear headphones aren’t at the top of the class in performance, but what they do have going for them is unrivaled quality and value at their (very reachable) price point. The company has created plenty of iterations since, including a Quad Driver and even an over-ear version, creatively called the Triple Driver over-ears. But when it comes to value for the money, we always come back to the original wired earbuds.
Alternatively, online calculators can be used. Once the sensitivity per volt is known, the maximum volume for a pair of headphones can be easily calculated from the maximum amplifier output voltage. For example, for a headphone with a sensitivity of 100 dB (SPL)/V, an amplifier with an output of 1 root mean square (RMS) voltage produces a maximum volume of 100 dB.
At the heart of the WH-1000xM3 is outstanding wireless sound. Sony’s LDAC technology delivers a wireless signal at what the company claims is three times the quality of standard Bluetooth streaming, and the headphones also support the latest aptX HD codec (with supported devices). The 1000xM3 even “upscale” wireless music from high-resolution audio devices using a special chip, helping to make music sound dynamic and beautiful, with authoritative bass and clear treble response held together by a well-rounded midrange.
What's most impressive about the EarFun Free is the features: Bluetooth 5.0, both USB-C and wireless charging and fully waterproof (IPX7), according to their specs. Do they sound fantastic? No, but they sound pretty good. They don't have the clarity of higher-end true wireless earbuds that cost $150 or more, but they do have plump bass and enough detail to avoid sounding dull. They're also pretty solid for making calls. An excellent value at less than $45.
Active noise-cancelling headphones use a microphone, amplifier, and speaker to pick up, amplify, and play ambient noise in phase-reversed form; this to some extent cancels out unwanted noise from the environment without affecting the desired sound source, which is not picked up and reversed by the microphone. They require a power source, usually a battery, to drive their circuitry. Active noise cancelling headphones can attenuate ambient noise by 20 dB or more, but the active circuitry is mainly effective on constant sounds and at lower frequencies, rather than sharp sounds and voices. Some noise cancelling headphones are designed mainly to reduce low-frequency engine and travel noise in aircraft, trains, and automobiles, and are less effective in environments with other types of noise.
Earphones might not be as eye-catching as headphones, but they can be much more convenient. Besides their size and weight, earphones are often more resilient than headphones when dealing with moisture. This is important if you want to listen to music at the gym. Earpads can get soaked and worn with a solid sweat, and they aren't built to withstand the regular, constant friction that comes with working out. Earphones can be built to be water- and sweat-resistant, and hold up much better to activity.
Earbuds have small speakers that rest on the ear canal of the wearer. These are usually much less expensive than on-ear and over-ear headphones and reproduce the sound well. However, outside sounds, such as traffic or power tools, can get past the earbuds and interfere with your enjoyment. Earbuds also don't stay in place very well if the wearer is moving much, such as exercising. These also are lower fidelity than on-ear and over-ear headphones.
