Beats Solo2 Wireless Design Picture

The Solo2 are well-crafted, comfortable on-ear headphones that feel a bit tight on the head. Luckily, they're very well padded, so the clamping force doesn't cause too much discomfort. The build quality feels sturdy and durable. They're wireless and stable enough to use while exercising. However,  the glossy plastic coating on the headband is susceptible to scratches and scuffs. It's also a little inflexible and might crack under sufficient physical strain.

Beats Solo2 Wireless Design Picture 2

The Solo2 have a sleek and polished design, that's eye-catching and looks high-end. They have a glossy finish and come in a variety of bright color schemes to suit your tastes. They have a large stylish headband and small well-padded ear cups that further add to their premium appeal.

Clamping Force
Show Help
What it is: The force that the headphones exert on your head, once you have them on. This is purely a measurement of the force applied, which does not take into account the earpad's surface area and the resulting pressure you will feel, on or around your ears.
When it matters: The tighter the headphones, the more force they put on your head. This can get uncomfortable or cause pain and soreness during long listening sessions.
:
1.1 lbs

The Solo2 are comfortable but slightly tight on the head. The headband is well built but feels a bit stiff, which in turn causes the headphone to exert a lot of pressure on the ears. Fortunately, the ear cups are very well padded making the clamping force a little less intrusive than expected. They won't be the most comfortable headphones for long listening sessions. However, they're a lot more comfortable than some other on-ear headphones.

Beats Solo2 Wireless Stability Picture

The Solo2 are a stable pair of headphones that won't easily fall if used while jogging or exercising. They exert enough clamping force on the ears to not sway and slip off mild physical activity. Additionally, they're wireless which means they won't yanked off your head because the audio cable got hooked on something. However, they're still a bit bulky and cumbersome, and the soft padding does get steamy during when sweating.

The Solo2 are well-built headphones that make use of high-end materials in their design. The headband is reinforced with a relatively thin metal frame that feels sufficiently sturdy. The ear cups are also sufficiently dense, and capable of handling a few falls without getting damaged. However, the plastic coating the headband and ear cups feels a little rigid and inflexible, which could crack under enough physical strain. The glossy finish also may get scratched by regular wear and tear and won't look as good over time.

Beats Solo2 Wireless Frequency Response

The Solo2 have an above-average sound that's a big improvement over the earlier beats models. The bass is punchy and does not overpower the instrumentals and vocals. The mid-range is slightly under-emphasized pushing the lead instruments a bit to the back of the mix. However, they still sound relatively crisp and detailed for most listeners. The soundstage, on the other hand, is not the best and doesn't feel immersive due to the small, shallow and closed ear cups.

5.3 Soundstage
Show Help
What it is: Soundstage qualities are not inherent to the audio content, the headphones have to 'create' them rather than 'reproduce' them. They determine whether the sound is perceived to be coming from inside or in front of the head, how open and spacious the soundstage is, how much the headphones acoustically interact with the environment, and how strong the phantom center is.

What it is: The average amount of deviation in Pinna-Related Transfer Function of the headphones, compared to that of a loudspeaker. Whether the soundstage is perceived to be unnatural, located inside or in front of the head, is dependent on this quality. The more the headphones activate the HRTF resonances of the ear (similar to what loudspeakers do), the more the soundstage will be pulled out from inside the listener's head. This quality affects both stereo and mono content.

Correlated Crosstalk
Show Help
What it is: How strong and solid the phantom center is. This is mostly a stereo quality and its effects on mono content are minimal. This test is sensitive to the phase of the crosstalk and whether it is produced acoustically or electronically.
When it matters: When a true reproduction of the stereo image is desired. A value of 0 indicates no crosstalk, or that the existing crosstalk is not correlated enough to affect the phantom center. A negative score means the crosstalk is out of phase with the original signal, resulting in a slightly wider stereo image at the expense of creating a 'hole' at the center of the stereo field. A positive score means the crosstalk is in phase and positively affecting the phantom center.
Good value: >1dB

Score components:

The Beats Solo2 have a better battery life than the Studio Wireless and take very little time to charge fully. Unfortunately, they do not have any power saving features or a downloadable app to personalize their sound profile. They also have a quite a bit of latency when watching videos, but it shouldn't be much of an issue for streaming audio. On the upside, they have a pretty good wireless range, so you do not need to have your Bluetooth device on you at all times.

They delivered a stable connection up to 40ft, which allows listeners to move about in their homes when the Bluetooth source is in another room. However, they're not the farthest reaching headphones and might not be ideal for large offices with a lot of walls. They're not too difficult to pair, and remember the last synced device but the press and hold procedure can get a little tedious if you often have to switch between Bluetooth sources.

The Beats Solo2 Wireless have a better battery life than the Studio Wireless and deliver up to 18.25 hours of continuous playback. They also take less time to charge via USB, which makes them decent headphones, to take on a long road trip or a particularly lengthy flight. However, you will still need to charge them throughout the day if you use them continuously. They also don't have any battery saving features, like an auto-off timer, and will quickly run out of power if you forget to turn them off.

Show Help
What it is This is the combination of the different use cases to evaluate how versatile the headphones are. Therefore an everyday headphone should be well-rounded enough to adapt to most situations and environments without significant losses in sound quality, design ergonomics or isolation.
Score components:
The Solo2 Wireless are a decently versatile set of on-ear headphones. They deliver a well-balanced sound and a good wireless design. They feel sturdy and have a comfortable fit but don't isolate very well, which limits a bit their use in loud, noisy environments.
7.3Critical Listening
Show Help
What it is The level of audio fidelity a headphone can reproduce. Therefore a balanced and true representation of bass, mids, treble, soundstage and imaging, as well as a comfortable listening experience, is essential for critical listening.
Score components:
The Solo2 Wireless have an above-average audio reproduction with a well-balanced bass-range that doesn't overpower the instruments and vocals. The high frequencies are also not too sharp, but due to their small ear cups, they can't create a spacious soundstage. This makes them a little less ideal for critical listening, but they sound good enough for most casual listeners.

What's the best Bluetooth transmitters to use with my wireless solos?
We are currently using a MEE Audio Connect Bluetooth transmitter with AptX, AptX(low latency) and dual pairing for one of our Bluetooth tests. It's easy to use and versatile, but it's a bit pricier than others. However, any Bluetooth 4.0 (or higher) transmitter would be a good fit for the Solo2 Wireless as they don't have the aptX codec and rely on the typical SBC connection with most Bluetooth devices. Also, we have yet to test for the AAC audio quality codec and cannot recommend an ideal transmitter for that purpose.
