If you want to play physical CDs and hear them out loud without plugging into anything, choose Kuephom CD Player; if you need wireless earbuds for streaming from a phone, tablet or laptop, choose Btootos Earbuds. They sit at opposite ends of the portable audio world, and the right one depends entirely on what your source is. One plays discs and doubles as a small speaker, the other streams Bluetooth audio straight into your ears. Neither replaces the other, so let me break down how each behaves in daily use.
• Kuephom CD Player — biggest strength: it plays CD, CD-R, CD-RW, MP3 and WMA discs, and it has a built-in speaker, so you can listen with nothing else attached. It also runs up to 8 hours on its 1500mAh battery with the included earphones, or about 5 hours through the speaker.
• Kuephom CD Player — biggest trade-off: it is a disc-first device. No Bluetooth, so anything you want to hear has to come from a disc or from a device wired into its 3.5mm AUX input.
• Btootos Earbuds — biggest strength: Bluetooth 5.4 with up to 15 metres of range, a claimed 6–8 hours per charge and up to 36 hours total with the case, plus IP7 waterproofing and touch controls.
• Btootos Earbuds — biggest trade-off: they are wireless only, with no headphone jack and no way to play a CD. Everything depends on a Bluetooth source and battery.
• Who each pick is for: the Kuephom suits someone with a shelf of CDs who wants portable, self-contained playback. The Btootos suit someone who streams music, podcasts and calls from a phone or laptop and wants nothing tethered.
Think of the Kuephom as a modern Discman. It measures 5.7 by 5.7 by 1.2 inches, so it drops into a bag or backpack without much fuss, and it comes with earphones, a USB-C charging cable, a 3.5mm audio cable, and a carry pouch. That little bundle matters: out of the box you can listen privately, connect it to a car stereo or external speaker, or just set it down and let the built-in speaker do the work.
Who should buy it? Someone who still owns CDs and wants to actually use them — at home, in the car via the AUX cable, or out and about with the speaker. It also makes a sensible gift for a family member or friend who prefers physical media. Who should skip it? Anyone whose entire library lives on a phone. There is no Bluetooth here, so if you expect wireless freedom, this is the wrong tool, and the speaker playback time is shorter than earphone playback, which is worth knowing before you plan a long trip around it.
Btootos Earbuds: Who It's For
The Btootos A90 Pro are true wireless in-ear buds built around Bluetooth 5.4. In plain terms, that means a fast, stable connection with low latency and a range of up to 15 metres, so you can leave your phone on a desk or a kitchen counter and keep listening as you move around. Pairing is automatic once you take them out, and they work with phones, laptops and other Bluetooth devices.
Sound comes from dual 14.2mm dynamic drivers with a 20Hz–20,000Hz frequency range and AAC/SBC support, and there is an ENC noise-reduction system aimed at call clarity rather than full active noise cancelling. The noise control listed is passive, which means the seal of the silicone tips does the blocking — that is why three sizes (S, M, L) are in the box. Battery figures are the headline: roughly 6 hours per charge, about 30 hours in the case, up to 36 hours total, and a 1.5-hour recharge via USB-C. An LED display on the case shows remaining power, and touch controls handle playback, calls and your voice assistant without reaching for your phone.
Who should buy them? Anyone who streams — music on the commute, podcasts at the gym, video calls at a desk. The IP7 waterproof rating and light silicone build make them a natural fit for workouts and outdoor use, and the ergonomic in-ear shape is designed to stay put. Who should skip them? If you want to listen to a CD, or you dislike in-ear tips, or you would rather not manage charging at all. There is no jack, so wired listening is not an option.
Side-by-Side: Which Should You Choose?
• Best for wireless streaming → Btootos Earbuds. Bluetooth 5.4 with 15m range and automatic pairing is built for phone and laptop streaming.
• Best for sharing music out loud → Kuephom CD Player. The built-in speaker lets others hear without anyone wearing anything.
• Best for workouts and weather → Btootos Earbuds. IP7 waterproofing and a secure in-ear fit are designed for sweat and rain.
• Best for long listening sessions → Btootos Earbuds. Up to 36 hours total with the case versus 8 hours on the Kuephom's internal battery.
• Best for car audio → Kuephom CD Player. The included 3.5mm cable connects straight to a car stereo's AUX input.
• Best for language learning or music practice → Kuephom CD Player. Repeat and adjustable playback speed are made for drilling a passage.
• Best for calls → Btootos Earbuds. ENC call noise cancellation and touch call management are the whole point of that design.
If I could only pick one, I would buy the Btootos Earbuds — for most people today, listening means streaming, and Bluetooth 5.4, up to 36 hours of total battery, IP7 protection and touch controls cover far more everyday situations than a disc player can. That said, my honest recommendation splits by library: if your music lives on CDs, the Kuephom is the more useful object, and its speaker and AUX output make it a genuinely flexible little player. If your music lives on your phone, the Btootos win comfortably. In my opinion, the Btootos A90 Pro is the better fit for a wireless, streaming-first routine.
how to use external headphones on mac
On a Mac, plug wired headphones into the 3.5mm jack if your model has one; the Kuephom's earphones can connect that way through its own 3.5mm output. For wireless listening, pair Bluetooth earbuds like the Btootos through the Mac's Bluetooth settings — they pair automatically once removed from the case.
how to connect mobile headphones
Wired headphones connect through a 3.5mm jack or an adapter. The Btootos earbuds connect wirelessly instead: enable Bluetooth on your phone, take the buds out of the case, and they pair automatically. The Kuephom's included earphones plug directly into its own 3.5mm headphone jack.
how to connect c port headphones
USB-C headphones plug into a USB-C port, and USB-C is also how both of these products charge — the Kuephom via its USB-C charging cable and the Btootos via their USB-C cable for the charging case. Note that the Btootos have no jack at all; they connect by Bluetooth, not by cable.
how to pack headphones
For travel, the Kuephom comes with a carry pouch and its 5.7 by 5.7 by 1.2 inch body fits in a bag or backpack. For the Btootos, drop the buds back into the charging case, which holds up to 30 hours of reserve power, and tuck the case — plus the spare silicone tips — into a small pocket.
