If you want true wireless freedom with a big, boosted low end and a charging case that tops up wirelessly, choose DRQQ Earbuds; if you need a wired USB-C connection with dual drivers for punchy bass and clear calls, choose BACKWIN USB C.
• DRQQ Earbuds — biggest strength: Truly wireless Bluetooth 5.1 with a 30-hour total battery figure (5 hours per charge plus 25 extra from the case), a large driver tuned for extra bass, and both USB-C and wireless charging options.
• DRQQ Earbuds — biggest trade-off: Battery per single charge is only about 4–5 hours, so heavy listeners will be reaching for the case often, and the plastic build is built for daily sweat and light rain rather than heavy abuse.
• BACKWIN USB C — biggest strength: A dual-driver setup (a 10 mm driver plus a balanced armature) with ENC noise reduction and a metal housing, all fed straight from a USB-C port with no battery to manage.
• BACKWIN USB C — biggest trade-off: It's wired, so there's no wireless freedom, and it only fits devices with a USB-C jack — older gear with a standard headphone jack won't work.
• Who each pick is for: DRQQ is for Android and iPhone users who want untethered listening with deep bass and a case that recharges easily. BACKWIN is for people on USB-C laptops, tablets and phones who want reliable wired audio with strong bass and call clarity.
The DRQQ Earbuds are built around one clear promise: big low end without a cable. Inside each earbud sits a dynamic driver covering a 20 Hz–20,000 Hz range, and the tuning leans deliberately toward extra bass. The Bluetooth 5.1 radio holds a connection up to about 10 meters, and the AAC codec matters here — if you're on an iPhone, AAC is the codec iOS handles natively, so you're getting a cleaner wireless stream than a basic SBC-only setup would give you.
Where the DRQQ really stands out is convenience. The charging case packs a 300 mAh battery that adds roughly 25 hours on top of the 5 hours in the buds, for a total of about 30 hours. The buds themselves take about 50 minutes to charge, and the case refills in about an hour and a half. You can top it up with a USB-C cable or drop it on a wireless charging pad — a genuinely useful feature if you already keep a pad on your desk. Touch controls handle play/pause, track skipping, volume, Siri, and calls, so you rarely need to pull out your phone. The ENC noise cancellation works on the microphone side to cut background noise during calls, and the IPX5 rating covers sweat and light rain, which is fine for workouts and commutes.
BACKWIN USB C: Who It's For
The BACKWIN USB C is a different animal entirely — it's a wired in-ear headphone that plugs into a USB-C port and draws its power from your device. That means no battery, no charging case, and no "did I charge these?" moment before a call. The dual-driver design pairs a 10 mm driver with a balanced armature, and the stated goal is dynamic audio with powerful bass plus high-definition reproduction from the armature. The 32 ohm impedance and 96 dB sensitivity suggest it's easy to drive from a phone or laptop without an external amp.
The call story is where BACKWIN leans hardest. It uses Environmental Noise Cancellation to filter background noise during calls — the kind of thing that helps in a noisy office, a train, or a busy street. The inline control panel handles volume, call management and playback, so you're not fumbling with on-screen controls. The housing is metal, which gives it a more substantial feel than a plastic shell, and it ships with ear tips in S/M/L so you can dial in the seal — and a good seal is exactly what makes deep bass actually land in an in-ear design. It also comes with a user manual and a one-year warranty.
Who should buy it: laptop and tablet users, people who take a lot of calls in noisy places, and anyone who prefers the reliability of a wire over Bluetooth pairing. Who should skip it: if you want wireless freedom, or if your phone or computer still uses a standard headphone jack rather than USB-C, this simply won't connect. The wired design is a feature for some and a dealbreaker for others.
Side-by-Side: Which Should You Choose?
• Best for wireless freedom → DRQQ Earbuds. Bluetooth 5.1 with a 10-meter range and no cable to snag on anything.
• Best for charging convenience → DRQQ Earbuds. The case accepts either a USB-C cable or a wireless charging pad.
• Best for call clarity in noisy places → BACKWIN USB C. ENC noise reduction plus an inline control panel built around call management.
• Best for bass depth through driver design → BACKWIN USB C. A dual-driver setup with a 10 mm driver and a balanced armature aimed at powerful, detailed bass.
• Best for durability feel → BACKWIN USB C. A metal enclosure versus the DRQQ's plastic body.
• Best for workouts and light rain → DRQQ Earbuds. The IPX5 rating is designed for sweat and wet weather; the BACKWIN sheet makes no such claim.
• Best for USB-C laptops and tablets → BACKWIN USB C. Plug-and-play over Type-C with nothing to charge.
In my opinion, most people shopping for headphones with deep bass should go with the DRQQ Earbuds. The wireless freedom, the roughly 30-hour total battery figure, the wireless-charging case and the IPX5 rating make it the more versatile everyday pick, and its large dynamic driver is tuned specifically for extra bass. That said, if your priority is call clarity in loud environments or you want wired reliability with a dual-driver bass setup and a metal build, I'd point you to the BACKWIN USB C instead. Two different jobs, two different answers — pick based on whether you want a wire or not. Either way, check the current price on Amazon before you commit, since that's the one thing that can tip a close call.
Headphones with good bass are ones whose driver design and tuning emphasize low frequencies — the deep, thumping part of the music. In this comparison, the DRQQ Earbuds use a large dynamic driver tuned for extra bass, while the BACKWIN USB C pairs a 10 mm driver with a balanced armature for powerful, detailed low end.
What headphones have deep bass?
Bass is the low-frequency portion of the audio range, roughly the bottom of the 20 Hz–20,000 Hz span both of these products cover. It's what you feel in drums, basslines and cinematic sound effects. Deeper, more controlled bass comes from driver design and a proper fit — a loose seal in an in-ear model quickly kills it.
Earbuds with good bass combine a bass-forward driver with a secure, sealed in-ear fit. The DRQQ Earbuds deliver it wirelessly via a large driver and Bluetooth 5.1, while the BACKWIN USB C delivers it over a wired USB-C connection with a 10 mm driver plus balanced armature. If you want bass without a cable, DRQQ is the fit; if you want bass with zero charging, BACKWIN is.
