• PLT Poly Blackwire 3320 — biggest strength: a flexible boom microphone, 180-degree pivoting speakers and simple USB-C or USB-A connectivity to a PC or Mac make it a plug-and-play headset for calls and streaming audio on a computer.
• PLT Poly Blackwire 3320 — biggest trade-off: it is wired, over-ear and has no active noise cancellation, so it is tethered to your desk and lets in room noise.
• BASN Bsinger Professional — biggest strength: dual dynamic drivers, an over-ear memory wire, six pairs of ear tips and two detachable cables give you a highly customizable, isolating in-ear fit.
• BASN Bsinger Professional — biggest trade-off: it is wired to a 3.5 mm jack, and the in-ear design means you must be comfortable with tips seated inside your ear canal.
• Who should buy PLT Poly Blackwire 3320: anyone who wants a secure, comfortable over-ear headset for calls and desktop streaming.
• Who should buy BASN Bsinger Professional: musicians, drummers and listeners who want detailed in-ear sound with a sealed fit.
The Blackwire 3320 is a communication tool first. The design brief is obvious from the spec sheet: a plush padded headband, pillow-soft ear cushions, 180-degree pivoting speakers and a flexible microphone boom. That combination exists to solve one problem — staying comfortable and audible through a long day of talking. The over-ear enclosure and hi-fi stereo drivers give you an immersive listening experience rather than a sealed one, which matters if you want to hear your own voice and the room around you while you work.
Connectivity is where it earns its keep. You plug into a PC or Mac over USB-C, or use the included USB-C to USB-A adapter if your machine only has the older rectangular port. There is nothing to pair, nothing to charge and no dongle hunt. Poly rates the frequency range at 20 Hz to 20,000 Hz with 32 ohm impedance and a dynamic driver, so music and streamed audio come through cleanly. The headset is listed as working with Zoom, Microsoft Teams and similar platforms, which tells you the target buyer is someone who lives in meetings and collaborative apps.
Buy it if you want a dependable, wired, over-ear headset for your desk — calls, webinars, and streaming through a computer. Skip it if you need something to wear on a stage, in a gym, or while walking around, because the wiring, the over-ear shape and the absence of active noise cancellation all point to a seated, plugged-in use case. It weighs 130 g, which is light enough for extended wear, but it is still a headset you keep near your machine.
The Bsinger Professional is the opposite philosophy. It is an in-ear monitor built around two dynamic drivers: a copper diaphragm layer for bass and a PET layer for crisp, clear highs. BASN's pitch is that this brings a "shimmer" to every instrument, and the spec backs up the intent — a 20 ohm impedance and 101 dB sensitivity mean these are easy to drive from a phone or a small interface without much amplification. The frequency range is the same 20 Hz to 20,000 Hz as the Poly, but the delivery is completely different because it seals into your ear canal.
The fit system is the headline. Flexible over-the-ear memory wire holds the cable in place, and six pairs of silicone ear tips in different sizes and styles let you dial in the seal yourself. That matters for isolation: BASN lists sound isolation as the noise-control method, so the design relies on blocking outside noise mechanically rather than electronically. In a loud room, on a stage or in a rehearsal space, that sealed fit is the whole game — it keeps the mix clear and undistorted at higher volumes.
What you actually receive is generous: the earphones, a durable woven cable for stage monitoring, a stereo mic cable for phone use, a portable case, the six tip pairs, a T-shirt clip, a cleaning brush and a 6.3 mm adapter. The gold-plated 2-pin connector means you can swap or upgrade cables later, which is a real long-term advantage. Buy it if you perform, record, drum, play guitar or simply want isolating in-ear sound you can customize. Skip it if you dislike things inside your ears, or if you need a boom mic for talking on calls — the mic here is a cable-mounted stereo mic, not a boom.

If you are hunting for the best neckband headphones for streaming, note that neither of these is a neckband — but the question behind it is about comfort and cable management, and the Bsinger's over-ear memory wire is the closer answer. If you are after the best multipoint kids headset for streaming, neither product offers multipoint pairing, so look elsewhere; both are single-connection wired designs. And if you want the best spatial audio earphones for streaming, be aware that neither data sheet lists spatial audio as a feature — the Poly leans on hi-fi stereo for immersion, and the Bsinger leans on driver layering and isolation.
In my opinion, the PLT Poly Blackwire 3320 is the safer buy for most people reading this, because it solves the everyday problem of talking and streaming from a computer with zero setup friction. It is the one I would pick for a home desk where meetings, webinars and streamed audio are the routine. The BASN Bsinger Professional is the better choice if your world involves a stage, a rehearsal room or a phone in your pocket, and you value a sealed, customizable in-ear fit over a boom mic. Decide by asking one question: do you talk into it, or do you listen through it? For streaming from a desk with calls mixed in, the Poly wins. For performing and isolating, the Bsinger wins.
FAQ
How to connect wireless stereo headphones
How to connect celly wireless stereo headphones
If your goal is a wireless connection, neither of these fits — both are wired designs. For a phone, the Bsinger is the practical one because its stereo mic cable ends in a 3.5 mm jack. The Poly is aimed at computers over USB rather than phones.
How to use celly wireless stereo headphones
Again, treat these as wired. With the Bsinger you fit the silicone tips, loop the memory wire over your ear, and plug into your device. With the Poly you put on the over-ear headset, adjust the boom mic and plug the USB cable into your computer, then use the touch volume control.
How to connect anc wireless stereo headphones
Neither product offers active noise cancellation. The Poly has no noise-control feature listed at all, and the Bsinger uses sound isolation — a physical seal from its ear tips — rather than electronic ANC. For true ANC you would need a different product entirely.
