If you want wired listening with 45 mm drivers and a balanced-connection option, choose Audio-Technica ATH-MSR7bBK; if you need Bluetooth, adaptive noise cancellation, and long battery life, choose Cambridge Audio Melomania P100. For calls, I’d lean toward the P100 for its wireless convenience, while the MSR7bBK is the more focused pick for listening through a cable. Neither is an open-ear design.
• Audio-Technica ATH-MSR7bBK: 45 mm True Motion drivers and a wired, balanced-connection option; the trade-off is that it has no listed Bluetooth or built-in battery.
• Cambridge Audio Melomania P100: Bluetooth, adaptive active noise cancellation, and up to 100 hours of stated battery life; the trade-off is that its over-ear design is heavier than the MSR7bBK’s listed 163 g.
• Choose the MSR7bBK if you want a cable-first headphone and value its specified driver and acoustic design.
• Choose the P100 if you want wireless freedom, noise cancellation, and features such as multipoint connection and a replaceable battery.
• For everyday calls away from a desk, the P100’s Bluetooth design is the more practical starting point; neither product’s listed features specify a dedicated call-microphone system.
The ATH-MSR7bBK is an over-ear wired headphone built around 45 mm True Motion drivers with diamond-like carbon-coated diaphragms. Audio-Technica also specifies a layered housing and triple-vent system designed to manage airflow and reduce unwanted vibration. Those details make this the more considered choice for someone who prioritizes a wired listening setup and wants a headphone designed around acoustic control rather than wireless features.
It includes a straight Y-type cable and has a 3.5 mm jack. The model also adds the option of a balanced connection, which may matter if your listening equipment supports that connection. Its specified frequency range is 15 Hz to 20 kHz. The listed weight is 163 g, a useful figure for comparing it with the substantially heavier P100, though weight alone cannot tell you how a headphone will feel over a long session.

For calls, the main limitation is straightforward: this is the cable-first option, and the listed features do not identify Bluetooth, active noise cancellation, or a call microphone. I’d choose it for a desk setup where a wired connection is welcome and listening is the priority. I’d skip it if you want to move between devices wirelessly, take calls while walking around, or avoid managing a cable.
The Cambridge Audio Melomania P100 is an over-ear Bluetooth headphone with adaptive active noise cancellation and a stated battery life of up to 100 hours. It also supports multipoint connection, so its feature set is geared toward switching between connected devices rather than staying tethered to one listening source. A replaceable battery and replaceable earcups are practical design details for someone thinking about longer-term ownership.
Its audio features include aptX Lossless, DynamEQ, and a seven-band adjustable EQ. The product information also describes a five-minute charge providing up to four hours of playback. Those features offer flexibility for different listening preferences and routines, while the included USB-C-to-3.5 mm cable gives you a wired option when that suits the situation. The listed weight is 0.7 kg, which is a meaningful trade-off next to the MSR7bBK’s 163 g.
For calls, Bluetooth and multipoint make the P100 the more convenient fit if you expect to use a headphone with more than one device. But its listed features do not specify a microphone system or call-quality performance, so I wouldn’t treat those features alone as proof that it is the best Bluetooth headset for calls. It is also over-ear, not open-ear; shoppers searching for the best open ear headphones for calls are looking for a different design category. Choose the P100 if its wireless and noise-control features matter more than low listed weight.
• Best for a cable-first setup → Audio-Technica ATH-MSR7bBK. It includes a straight Y-type cable and a 3.5 mm jack, with no battery requirement listed.
• Best for Bluetooth listening → Cambridge Audio Melomania P100. Bluetooth is built into its design, making it the natural choice when you want to leave the cable behind.
• Best for long stretches without charging → Cambridge Audio Melomania P100. Its stated battery life is up to 100 hours, and its battery is user-replaceable.
• Best for a lighter listed weight → Audio-Technica ATH-MSR7bBK. Its listed weight is 163 g, compared with 0.7 kg for the P100.
• Best for adaptive active noise cancellation → Cambridge Audio Melomania P100. The MSR7bBK lists sound isolation, not active noise cancellation.
• Best for a balanced-connection option → Audio-Technica ATH-MSR7bBK. That connection option is specifically identified as part of this model’s design.
• Best for adjustable sound settings → Cambridge Audio Melomania P100. Its listed features include a seven-band EQ and DynamEQ.
• Best for calls while moving between devices → Cambridge Audio Melomania P100, with a caveat. Bluetooth and multipoint suit that routine, but the product details don’t specify call-microphone performance.
The call comparison is less conclusive than the listening and connectivity comparison. The P100 has more obvious everyday convenience for wireless calls, but neither specification sheet provides enough microphone detail to make a firm claim about call clarity. If your main concern is taking calls, check the current product information for microphone and call-control details before deciding.
The phrase “rotatable ear cups on ear headphones for calls” also points toward a specific feature and fit that neither product’s listed details establish. Both are over-ear headphones, and neither sheet identifies rotatable ear cups. I wouldn’t choose either on the assumption that it has that feature.
I’d choose the Cambridge Audio Melomania P100 for calls and everyday flexibility because Bluetooth, multipoint, and adaptive noise cancellation make it the more convenient match for moving between devices. Its replaceable battery and up-to-100-hour stated runtime add practical appeal. I’d choose the Audio-Technica ATH-MSR7bBK instead if my priority were a lighter, wired listening setup with 45 mm drivers and a balanced-connection option. The P100 is my pick for calls, but I’d verify microphone details if call quality is the deciding factor.
The P100 has Bluetooth and multipoint connection, which make it more convenient for wireless calls across devices. Neither product’s listed specifications identify a microphone system or provide call-quality details, so the available information doesn’t establish which sounds better on a call.
Yes. The P100 uses Bluetooth and also includes a USB-C-to-3.5 mm cable for wired listening. Its listed features include adaptive active noise cancellation and a stated battery life of up to 100 hours.
Active noise cancellation is not listed for the ATH-MSR7bBK. Its noise-control feature is described as sound isolation, while the P100 specifically lists adaptive active noise cancellation.
The answer depends on what matters most to you. The P100 lists a much longer battery life and replaceable earcups, while the ATH-MSR7bBK has a lower listed weight. The specifications don’t establish which one will feel more comfortable to every listener.
