How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to breathe wireless life back into a pair of wired Beats Studio 2 headphones you already own, choose Bolle & Raven Bolle&Raven; if you need a complete, modern pair of noise-cancelling over-ear headphones for commuting, travel, gaming and everyday listening, choose OneOdio Focus A5.
These two products are not really rivals in the usual sense. One is a small adapter that solves a very specific problem, and the other is a full set of headphones built for daily use. The right pick comes down to whether you are upgrading something you already have or buying something new. Here is how I break it down.
• Bolle & Raven Bolle&Raven — biggest strength: It turns a wired pair of Beats Studio 2 headphones into a wireless setup, with a built-in mic, on-board controls and up to 12 hours of playback.
• Bolle & Raven Bolle&Raven — biggest trade-off: It is a single-purpose accessory. It is modeled for the Beats Studio 2.0 only and is explicitly not compatible with Beats Solo 2, so it is useless if you do not own that exact model.
• OneOdio Focus A5 — biggest strength: A complete headphone package with Hybrid ANC rated to -45dB, LDAC Hi-Res wireless audio, up to 75 hours of playback and a low-latency game mode.
• OneOdio Focus A5 — biggest trade-off: You are buying an entire set of over-ear headphones rather than upgrading hardware you already own, and it weighs 265 g, which is substantial for all-day wear.
• Bolle & Raven Bolle&Raven is for: Beats Studio 2.0 owners who want to cut the cable without replacing their headphones.
• OneOdio Focus A5 is for: Anyone who wants one pair of modern headphones for commuting, flights, calls, music and gaming.
Bolle & Raven Bolle&Raven is a wireless Bluetooth adapter designed specifically for the Beats Studio 2.0. That specificity is the whole point. Instead of asking you to replace your headphones, it plugs into the model you already own and gives it the freedom of a cable-free connection. The adapter handles volume and song skipping, and Apple and Android devices are both supported. A built-in mic means you can jump from a phone call back to music without fumbling for your phone. The internal battery is rated for up to 12 hours of playback and talk time, which comfortably covers a workday of listening or a long stretch of calls. In the box you get the adapter itself, a charging cable, a user guide and an 18-month guarantee backed by the brand's customer care team. It comes in grey and measures roughly 1.5 x 2 x 3 inches, so it stays discreet once attached.
This is a product for a narrow but very real audience: people who love their wired Beats Studio 2 headphones and do not want to retire them. If that is you, the adapter is the cheaper-feeling path to wireless convenience without abandoning a familiar fit and sound. It is also a neat fix for anyone who keeps a dedicated pair of Studio 2s for travel or desk work and wants one less cable in the bag.
Who should skip it? Anyone who does not own Beats Studio 2.0 headphones. The adapter is modeled for that model only, and the brand is clear that it is not compatible with the Beats Solo 2. If your headphones are a different model, this is not the product for you — check the model on your earcups before ordering. And if you are starting from scratch with no headphones at all, an adapter has nothing to attach to.
OneOdio Focus A5 is a self-contained wireless headphone with hybrid active noise cancellation rated up to -45dB. The brand's claim is that it silences up to 98% of low-frequency noise — the drone of plane engines, subway rumble and office chatter — which is exactly the kind of noise the average commuter wants gone. It also supports LDAC, the Hi-Res Audio Wireless codec that transmits at up to 990kbps, roughly three times the data of standard Bluetooth audio. In practice, that matters if you stream higher-quality sources and want more detail and dynamics over a wireless connection. Bluetooth 5.4 handles the pairing, with a range of about 10 meters.
Battery life is the headline number here: up to 75 hours of playback, dropping to about 45 hours with ANC switched on. A 10-minute charge is rated to give you 10 hours of listening, which is genuinely useful when you are heading out the door and realize the battery is low. There is a low-latency game mode with latency as low as roughly 0.065 seconds, keeping audio and on-screen action in sync for mobile gaming and video. The drivers are dynamic with a 20Hz–40,000Hz frequency range, 32-ohm impedance and 105dB sensitivity. Fit gets real attention too: oval over-ear cushions in protein leather and a headband that adjusts to your shape. Controls are physical push buttons, and the build mixes ABS, leather, metal, plastic and stainless steel. It comes with a USB-C charging cable and a two-year warranty, and it weighs 265 g. The finish is black.
Side-by-Side: Which Should You Choose?
• Best for upgrading headphones you already own → Bolle & Raven Bolle&Raven. Nothing else here gives a wired Beats Studio 2 a wireless second life.
• Best for noise cancellation → OneOdio Focus A5. Hybrid ANC rated to -45dB is a core feature; the adapter has none.
• Best for battery life → OneOdio Focus A5. Up to 75 hours (45 with ANC) versus up to 12 hours on the adapter.
• Best for calls and quick controls → Tie. Both offer a built-in mic and physical controls for volume, skipping and switching between calls and music.
• Best for Hi-Res wireless audio → OneOdio Focus A5. LDAC support at up to 990kbps is a clear advantage for quality-focused listeners.
• Best for gaming and video → OneOdio Focus A5. The low-latency game mode targets roughly 0.065 seconds of lag.
• Best for travel and commuting → OneOdio Focus A5. ANC plus 45-hour ANC endurance is built for flights and noisy transit.
• Best for a narrow, specific fix → Bolle & Raven Bolle&Raven. If you own Beats Studio 2.0 and only want wireless freedom, it does exactly one job well.
In my opinion, the OneOdio Focus A5 is the better buy for most people. It is a complete product — noise cancelling, LDAC audio, a huge battery, a game mode and a two-year warranty — so it stands on its own no matter what you already own. The Bolle & Raven adapter is excellent at one very specific task, and if you own Beats Studio 2.0 headphones and are not ready to let them go, I would recommend it without hesitation. But it only makes sense inside that narrow window. If you are deciding between the two and do not already own a pair of Beats Studio 2, the Focus A5 is the one I would pick. Check the current price on Amazon for both before you commit.
