    Q: It says on the title ‘true wireless’ but in the specs under ‘true wireless’ it says no- what is true wireless and which is it? Yes or no. Thanks!

    A: Best Buy considers "True Wireless" to mean that they do not have wires connecting the cups together. Their meaning would only be possible with in-ear bluetooth. Its confusing, but Solo 4s are bluetooth wireless on ear headphones and do not require wires to connect to bluetooth enabled devices.

    Q: do they come with noise cancellation?

    A: no, you would have to move up to the Studios

    Q: Are these ear cushions going to be okay in a gym environment where sweating will be involved? I've had some headphones cushions that have broke down in these situations.

    A: Yes all the beats headphone I have dont break but If you sweat alot use the wipe but The one I have I have for three years and look almosst brand new This good headphone for gym,Office,school,travling. You can wait until black firday retail going be like 130-160 like projected as now.

    Q: Can these be paired and used to listen to the t.v. if it's bluetooth enabled?

    A: Yes, I tried and it’s great but maybe it depends on the TV’s brands and their features that you have at your home. As long you’re using the Apple TV it’s automatically connecting but if you’re using a normal tv you’re going to pair it and to unpair anytime.

    Q: how do i turn on/off beats

    A: There’s a little button under the ear.

    Q: Can these be used to here the audio of a smart TV?

    A: You can use Solo 4 to connect to any bluetooth enabled device. If your SmartTV supports Bluetooth, Solo 4 will connect

      I love Beats

      The Beats Solo 4 True Wireless On-Ear Headphones are absolutely fantastic! The sound quality is crisp and immersive, with deep bass and clear highs that make every song feel like a live performance. Whether I’m listening to music, podcasts, or watching videos, the audio experience is always top-notch. The wireless connectivity is seamless—pairing with my devices was super easy, and the connection is stable even when I move around. The battery life is impressive, lasting all day with plenty of juice left for a quick charge when needed. What really stands out is the comfort. The on-ear design is lightweight, and the ear cushions are so soft, I can wear them for hours without any discomfort. The sleek, stylish design is the icing on the cake—they look as good as they sound! I highly recommend the Beats Solo 4 for anyone looking for great wireless headphones that deliver premium sound, style, and comfort. Beats nailed it with these!

      BEST Headphones

      The Beats Solo 4 headphones feature the iconic Beats aesthetic with a sleek, minimalist design and vibrant color options. They are compact and lightweight, making them highly portable. The adjustable headband and cushioned ear cups provide a decent fit, though users with larger ears may find them slightly snug during extended use. The build quality feels premium, with durable materials that can withstand everyday wear and tear. Audio Performance As expected from Beats, the Solo 4 delivers a bass-heavy sound profile, making it a great choice for hip-hop, EDM, and pop music fans. The mids and highs are clear but can feel slightly overshadowed by the powerful low end. While audiophiles may find the soundstage somewhat limited, casual listeners will likely enjoy the energetic and immersive audio. Battery Life Battery life is a strong point for the Solo 4. With up to 40 hours of playtime, these headphones easily last through multiple days of use on a single charge. The Fast Fuel feature is a standout, providing up to 3 hours of playback with just a 5-minute charge—perfect for last-minute needs. Features and Connectivity The Solo 4 offers seamless wireless connectivity via Bluetooth, with minimal latency and stable performance. Pairing with Apple devices is especially smooth thanks to the integration of the W1 chip. The on-ear controls are intuitive, allowing users to adjust volume, skip tracks, and take calls without needing to reach for their devices. However, noise isolation is passive rather than active, meaning they rely on the snug fit of the ear cups rather than advanced ANC technology. Comfort While the headphones are comfortable for short to moderate listening sessions, the on-ear design may cause discomfort during extended wear, especially for users sensitive to pressure on their ears. This is a common trade-off with on-ear headphones compared to over-ear models. Price The Beats Solo 4 headphones are positioned in the mid-to-high price range. While they offer great design and bass-heavy sound, some competitors in this range provide features like active noise cancellation or higher audio fidelity. Verdict The Beats Solo 4 headphones are a great option for those who value style, portability, and bass-forward sound.

      Great headphones for the price

      The beats solo 4 headphones are great for the price. The sound quality is much improved compared to the last generation with the addition of spatial audio, and the battery life has been relatively improved, which can last through at least a week through regular usage. The bass can be a little bit heavier in my opinion but that’s the only thing that I believe could be refined or improved in my opinion. Sadly, they are not noice cancelling, nor do they have transparency mode, but they do provide enough blockage to make up for the lost of not having the ANC feature. FYI, if you are an audiophile, I think looking at the competition would be a great option to see what suits you best, as these headphones do not offer the best sound quality on the market, and there are plenty more great choices to choose from.
