Harman Kardon Harkar BT Review | 93 Data compared

The Harman Kardon BT is a strikingly designed, premium pair of over-ear Bluetooth headphones constructed mostly of solid aluminum, featuring an unusual self-adjusting dual-band design. On the positive side, they offer exceptional durability, easy Bluetooth pairing with apt-X support, stellar battery life, and a highly secure, tight fit that makes them excellent for running and active use. They also provide strong natural noise isolation without needing active noise-cancellation, making them highly portable when rotated flat into their included carrying case. However, the headphones suffer from several design and audio drawbacks. The tightly sealed, closed-back fit creates an unnatural echo and heavy bass reverberation that can drown out the midrange frequencies, making choruses feel muted on bass-heavy tracks. Furthermore, the soundstage separation is weak, making it difficult to distinguish left and right channels. From a hardware perspective, the control buttons are poorly placed, small, and untextured, while the proprietary miniature headphone jack forces users to rely strictly on the included charging and 3.5mm adapter cables.

The Harman Kardon BT headphones offer a sound signature that emphasizes low frequencies, providing an impressive, deep bass response with plenty of "slam" and impact across both wired and wireless modes. While the bass has an upper-range emphasis that adds warmth, it is somewhat boomy and bleeds into a midrange that feels a bit dry, indistinct, and veiled. The treble remains well-behaved and non-sibilant, though it has a metallic quality and lacks sparkle. Curiously, while the large rectangular earcups provide an unusually big soundstage for a closed-back headphone, they suffer from imaging issues, an off-kilter channel balance, and inconsistent vocal placement. Key Pros and Cons Pro: Deep, hard-hitting bass impact. Pro: Generous soundstage size. Pro: Non-fatiguing, non-sibilant highs. Pro: Intuitively placed wireless controls. Con: Bulky, heavy, and uncomfortable design. Con: Excessive clamping force limits long listening sessions. Con: Boomy bass bleeding into a dry, veiled midrange. Con: Off-center soundstage imaging and channel imbalance.

The Harman Kardon Premium Bluetooth Over-Ear Headphones ($249.99) offer a highly contemporary, throwback-inspired design featuring rectangular memory-foam earpads, a dual leather and metallic headband, and flat-folding earcups for transport. Weighing 0.62 lbs, the headphones provide an overall comfortable, contouring fit with controls and an integrated microphone built directly onto the left earcup. Performance-wise, they deliver rich, robust sound with clear midrange acoustics, strong bass handling, and unobtrusive treble at medium volumes, avoiding the flat distortion common in cheaper Bluetooth models. The audio quality is maximized further when used with the included wired cable, and the device is fully optimized to support lossless Apt-X technology. However, the review highlights several notable design and functional drawbacks. A major downside is the proprietary charging system, which relies on a non-standard 3.5mm-to-USB inline cable; if this unique cord is lost, it cannot be replaced with a standard mini or micro-USB cable. Additionally, adjusting the fit is inconvenient, requiring partial disassembly of the headset to swap between the included small and large metallic headbands. Lastly, while the integrated microphone functions well, its clarity is highly...

The AVForums review praises the Harman Kardon BT headphones for their superb industrial design, combining robust materials with a lightweight feel, alongside an accurate, revealing sound profile that avoids typical Bluetooth compression. Key benefits include the inclusion of two different metal headbands for a customizable fit, though the design does not offer active noise cancellation (ANC), relying instead on passive isolation. Conversely, the review highlights that the lack of ANC and fewer features compared to competitors like the PSB M4U2 reduce its overall versatility. Furthermore, the audio signature, while accurate, may not satisfy users seeking a heavily bass-driven sound, making it better suited for critical listening rather than consumer-oriented, punchy audio.

The Harman Kardon BT headphones offer exceptional build quality and a powerful, distortion-free sound signature, making them a high-performing wireless option for bass enthusiasts. While earning an Editors' Choice award for its design, the headset features a heavily sculpted, low-end focused audio profile and a unique rectangular design that may not suit all tastes. Notable drawbacks include a maximum volume that is lower than some wired alternatives and a slightly cumbersome headband-swapping mechanism.

The Harman Kardon BT over-ear wireless headphones feature an industrial design with a sandblasted steel outer frame, magnetic leather earpads, and unique rectangular earcups that offer a comfortable, sturdy fit and decent passive noise isolation. Its audio performance delivers excellent clarity, a neutral and well-balanced presentation, accurate timing, and a smooth midrange. Other major advantages include an impressive battery life of approximately 15 hours at medium volume and a premium, durable steel-framed build quality that outshines plastic competitors. However, the headphones suffer from a polite sound presentation that lacks outright punch and bite, which is confirmed by the fact that they sound noticeably more powerful and dynamic when using the wired connection. Physical usability presents additional drawbacks, notably a fiddly power and pairing button that hides its own indicator LED during use, alongside a shared charging/audio port that prevents you from listening to music while charging. Furthermore, they are not highly portable due to their large size, and they lack active noise-cancelling technology for travel.

The Harman Kardon BT ($250) is a premium pair of over-the-ear Bluetooth headphones praised for delivering well-balanced, natural, and accurate sound quality with tight, snappy bass and a warm treble profile. Designed with a modern take on an old-school aesthetic, the headphones feature robust build quality utilizing a double metal headband system. Harman Kardon includes two interchangeable metal bands (small and large) to help users customize the fit to their head size. Additionally, the earcups utilize comfortable memory-foam padding that provides a tight seal, and the entire unit folds flat to easily fit into an included carrying case.

The review of the Harman/Kardon BT over-ear Bluetooth headphones emphasizes a premium initial impression, highlighting their nice design, expensive construction materials, and good overall sound quality. Mechanically, the closed-back headphones utilize 40 mm dynamic drivers with a 32-ohm impedance, delivering a reliable frequency response from 16 to 20,000 Hz. They also provide a decent battery life of approximately 12 hours and support multiple high-quality audio codecs, including AAC and AptX. However, the review outlines several significant functional drawbacks. Users may find that the wearing comfort could be better, and the ear cup housing suffers from being quite microphonic, which can cause annoying structure-borne noise during movement. Additionally, the included 1.4-meter audio cables utilize non-standard plugs, making replacements difficult. Usability is further limited because you cannot use the headphones while they are charging, and they completely lack Active Noise Cancellation (ANC) features.

The Harman/Kardon BT Premium Wireless Over-Ear Headphones ($250) feature an Apple-inspired, boxy aesthetic utilizing high-quality steel frames, interchangeable headbands, and leather earcups. In terms of pros, the headphones perform exceptionally well in their secondary wired mode, delivering clean sound, a controlled bass, low-distortion midrange, and high microphone clarity for phone calls and Siri requests. Additionally, they fold flat for easy transit, offer an improved 12-hour rechargeable battery life compared to prior models, and can be charged via any standard USB port. However, the headphones suffer from notable design and wireless performance flaws. Critics note the unergonomic, retro-looking industrial design causes ear perspiration, and the controls on the left earcup are poorly labeled. When used wirelessly via Bluetooth, users experience a high-pitched droning sound during quiet tracks, reduced treble and midrange clarity, and a flat audio signature unless volumes are manually synchronized across devices. Most critically, the built-in microphone functions poorly over Bluetooth, resulting in muffled call quality and frequent Siri failures, while the physical three-button remote becomes entirely non-functional in wired mode.
