If you want comfortable, wood-housed wired headphones for long home listening, choose SIVGA Luan Brown Open-Back; if you need a lightweight-feeling open-back option for home, work, or gaming, choose Amazon Renewed Sennheiser HD 505. For seniors choosing headband headphones, my pick is the SIVGA when its detachable cable and listed one-year warranty matter most.
SIVGA Luan Brown Open-Back vs Amazon Renewed Sennheiser HD 505 at a Glance
• SIVGA Luan Brown Open-Back: Wood enclosure, 50 mm dynamic driver, and detachable cable; its main trade-off is that the sheet does not specify an open-back design or a reduced-clamping-force fit.
• Amazon Renewed Sennheiser HD 505: Open-back construction, velour ear pads, and a lightweight headband with reduced clamping force; its main trade-offs are a fixed included cable and a listed 90-day limited warranty.
• Choose SIVGA for a removable cable, wood exterior, and included leather carrying case.
• Choose the HD 505 for a clearly specified open-back design and stated suitability for home listening, work, and gaming.
• For seniors, either could suit home listening, but the stated fit details point different ways: SIVGA emphasizes lightweight comfort, while the HD 505 specifically notes reduced clamping force.
The Luan is a wired, over-ear headphone with a 50 mm dynamic driver and a wood enclosure. Its listed frequency range is 20 Hz to 20 kHz, and its impedance is 38 ohms. Those figures describe the headphone’s stated audio range and electrical specification; they do not, by themselves, establish how it will sound with a particular recording or device. SIVGA describes its intended presentation as balanced and high-resolution, with a design meant for extended listening.
Comfort is part of its appeal on paper. It has an ergonomic design, lightweight construction, and skin-friendly velvet ear pads. The product details also describe a velvet headband pad and oval, large-size ear pads. That combination makes it a sensible option to consider for someone who listens at home for long stretches and prefers soft fabric contact around the ears. The solid wood housing gives it a distinct material choice, while a detachable 3.5 mm cable offers the practical option of replacing the cable rather than treating it as a permanent part of the headphones.

Amazon Renewed Sennheiser HD 505: Who It's For
The HD 505 is explicitly described as an open-back, over-ear wired headphone. The stated frequency range is 20 Hz to 20,000 Hz. Its product details list a planar magnetic driver, while the features emphasize clear, spacious listening for music, work, and gaming. Open-back construction is the clearest differentiator here: it is the one to consider if that design is a firm requirement. The sheet does not list noise control, so neither headphone should be chosen as a noise-isolating option.
The package details list a 1.80 m cable with a 3.5 mm jack, a screw-on 3.5 mm to 6.35 mm adapter, and a drawstring bag. The cable is included as a fixed part of the listed setup; unlike the Luan, the HD 505’s sheet does not describe it as detachable. The listed warranty is 90 days limited. Skip it if a detachable cable, a wood enclosure, or the Luan’s listed 12-month warranty is more important to you than the HD 505’s specified open-back design and reduced clamping force.
• Best for a clearly specified open-back design → Amazon Renewed Sennheiser HD 505. The Luan’s sheet does not identify its design as open-back.
• Best for a detachable cable → SIVGA Luan Brown Open-Back. Its replaceable 3.5 mm cable is a practical point of difference.
• Best for a stated reduced-clamping-force fit → Amazon Renewed Sennheiser HD 505. The Luan lists comfortable materials and a lightweight design but does not specify reduced clamping force.
• Best for a wood enclosure → SIVGA Luan Brown Open-Back. The HD 505 uses a plastic enclosure.
• Best for included carrying options → SIVGA Luan Brown Open-Back. It includes a leather carrying case and hemp bag; the HD 505 includes a drawstring bag.
• Best for a listed 12-month warranty → SIVGA Luan Brown Open-Back. The HD 505’s sheet lists a 90-day limited warranty.
• Best for work or gaming as stated use cases → Amazon Renewed Sennheiser HD 505. Its features specifically mention both; the Luan is positioned around home and studio listening.
• Best for a 50 mm dynamic driver → SIVGA Luan Brown Open-Back. Its driver type and size are specified, while the HD 505 is listed with a planar magnetic driver and no driver size.
My Verdict
I would choose the SIVGA Luan Brown Open-Back for seniors who mainly want a comfortable wired headphone for home listening and value a detachable cable, soft velvet ear pads, a carrying case, and the listed one-year warranty. Those are concrete everyday-use advantages, not a claim that it will fit every listener.
I would switch to the Amazon Renewed Sennheiser HD 505 if open-back construction or reduced clamping force were my deciding needs. In my opinion, the Luan is the more practical pick when the removable cable and included accessories lead the decision; the HD 505 is the more direct fit when its specified design and use cases do.
Fit descriptions are not interchangeable. The Luan’s sheet emphasizes lightweight construction, ergonomic design, and velvet padding. The HD 505 specifically adds reduced clamping force. If pressure around the head is a concern, that distinction is worth weighing, while recognizing that written fit features cannot establish how either model will feel on a particular person.
Also consider the cable and the included accessories. The Luan’s cable is detachable, and its package lists both a hemp bag and leather carrying case. The HD 505 includes a 1.80 m cable, a screw-on adapter, and a drawstring bag. If you want to compare current prices, check the latest price on Amazon rather than relying on an outdated figure. For shoppers looking for the best foldable earphones for seniors, neither sheet describes a folding mechanism, so these are not a clear match for that specific requirement.
There is no single fit that will suit every listener. The Luan lists lightweight construction and velvet comfort features, while the HD 505 specifically lists a lightweight headband and reduced clamping force. Consider which fit details matter most, along with the cable and warranty differences.
Neither product’s details list noise control. The HD 505 is explicitly open-back, so it is a poor match if your main requirement is blocking outside sound. The Luan’s supplied details do not specify an open- or closed-back design.
The SIVGA Luan has a detachable, replaceable 3.5 mm cable. The HD 505 is listed with a 1.80 m cable, but its details do not say that the cable detaches. Both include an adapter for a 6.35 mm jack.
Both listings describe comfort features for extended listening. The Luan highlights a lightweight design and velvet padding; the HD 505 highlights a lightweight headband, reduced clamping force, and plush velour ear pads. The best choice depends on how those fit details align with the listener’s preferences.
