11.11 sale picks: Noise cancelling earbuds, headphones, tablet, more

Ask anyone with a shopping list, and November is when it comes out of the drawer. The month tends to bring deal labels, countdown timers and limited time tags to listings across Amazon, and the first week is when many people start comparing.

Knowing which tags are worth a second look is half the job.

November deals on tech products

Gadinsider has compiled five products that carry sale-style labels or sit in the November shopping mix. They span audio, health and everyday tech: TOZO noise-cancelling earbuds, Pointcinco over-ear headphones, a COSLUS water flosser, a UBDXBD Android tablet and a CHIFENCHY speaker with a phone stand.

1. TOZO NC9 hybrid active noise cancelling wireless earbuds

The TOZO NC9 is a pair of in-ear wireless earbuds with hybrid active noise cancelling and a charging case that shows the remaining battery. The listing is marked as Amazon's Choice and a limited-time offer. TOZO says it reduces noise by up to 45 dB.

Key features and specs

• Noise cancelling: Hybrid ANC, up to 45 dB, per TOZO
• Modes: ANC and Transparent Mode
• Calls: 6 microphones with ENC noise reduction
• Drivers: 10mm, with OrigX Acoustic 2.0 sound technology
• Sound options: 32 EQ settings through the TOZO app
• Battery with case: Up to 60 hours (ANC off) or 40 hours (ANC on)
• Battery per charge: 14 hours (ANC off) or 10 hours (ANC on)
• Charging: About 2 hours; case shows remaining battery
• Water resistance: IPX8
• Connectivity: Bluetooth 5.3, range up to 15 metres
• Fit: Six sizes of replaceable ear caps
• Colour: Dark Black

Performance

The figures in the listing prove that noise cancelling consumes power since it reduces the playback time from 14 hours to 10 with ANC turned on. Transparent Mode allows hearing of what is going on around you, and TOZO claims that it is useful outside. The 45dB figure and the sound quality claim are provided by TOZO itself.

Pros

• Hybrid ANC with a Transparent Mode
• Case shows remaining battery
• IPX8 water resistance and six ear cap sizes

Cons

• Playtime falls with ANC on, from 60 hours to 40 with the case.
• The listing does not name supported audio codecs.
• No warranty details given

2. Pointcinco bluetooth noise-cancelling headphones

The Pointcinco is a pair of foldable over-ear headphones with active noise cancelling, a Transparency mode and Bluetooth 6.0. The listing carries a limited time deal label. It can connect by Bluetooth or by a 3.5mm cable.

Key features and specs

• Noise control: ANC, transparency and ANC off
• Drivers: 40mm composite diaphragm
• Connectivity: Bluetooth 6.0, plus 3.5mm wired connection
• Battery: 600 mAh; up to 50 hours with ANC on and 80 hours with ANC off, per Pointcinco
• Charging: About 2.5 hours for a full charge
• Comfort: Memory foam ear cups wrapped in protein leather, self-adjusting headband
• Portability: Folds to about 50% of its size
• Colour: Black

Performance

The 80-hour claim is when the noise cancellation is off; hence, the 50-hour mark should be taken if the ANC is turned on. It’s the wired model that makes more sense, as it can connect to in-flight entertainment systems as well as old devices, according to the product listing. Pointcinco claims the ANC concentrates on low frequencies only.

Pros

• Wired and Bluetooth connections
• Foldable design for travel
• Long claimed battery life

Cons

• No noise-cancelling depth figure given
• The 80-hour claim only applies with ANC off.
• No warranty details or companion app mentioned

3. COSLUS C20 water dental flosser

The COSLUS C20 is a cordless water flosser with a 300 ml tank and five interchangeable tips. The listing is marked as 'Amazon's Choice' and a 'limited-time deal'. COSLUS says it is ADA accepted, which is the seller's claim.

Key features and specs

• Tank: 300 ml, BPA-free
• Pulses: 1,400 to 1,800 per minute, per COSLUS
• Modes: 3, with multiple pressure settings
• Tips: 5 interchangeable
• Battery: About 3 hours to charge, up to 30 days of use, per COSLUS
• Charging: USB cable included; adapter not included (any 5V DC USB-A adapter works)
• Water resistance: IPX7
• Durability claim: Built to last 3 years under typical use, per COSLUS
• Colour: Black

Performance

The capacity of a 300 ml tank implies a need for fewer top-ups during sessions, while 30 days of battery life implies infrequent charging, but this will be determined by the frequency of usage. The listing recommends using the device in Soft mode while the mouth is shut to give the gums time to get used to it.

Pros

• Large 300 ml tank
• Five tips, three modes and several pressure settings
• IPX7 water resistance and USB charging

Cons

• Power adapter is not included.
• Dental benefit claims come from the seller.
• Packaging may vary, though contents are said to be the same.

4. UBDXBD 11-inch Android 16 tablet with keyboard

The UBDXBD is an 11-inch Android tablet that the listing sells as a 2-in-1 with a keyboard and mouse. It runs Android 16 and includes Gemini AI, per the seller.

Key features and specs

• Screen: 11 inches, 1920 x 1200 resolution
• Operating system: Android 16, with Gemini AI
• Storage: 128GB built-in with microSD up to 1TB, per the description (the specs table says 32GB)
• Connectivity: Dual-band 5G Wi-Fi and Bluetooth 5.0
• Battery: 8000 mAh
• Cameras: 16MP rear and 8MP front
• Streaming: Widevine L1, per the listing
• Model: K70PROHHJ

Performance

The 11-inch display is adequate for streaming, video chat, and taking notes, and the keyboard accessory is meant for minimal productivity tasks. Widevine L1 certification, assuming it is accurate, will be sufficient for watching HD videos through streaming sites, but verify this before depending on it. The product listing fails to identify the chip inside, hence no insight into its performance under pressure applications.

Pros

• 11-inch screen at 1920 x 1200
• Android 16 with Gemini AI, per the seller
• microSD expansion up to 1TB

Cons

• Memory and storage figures conflict between the specs table and the description.
• The processor is not named
• The listing is unclear on whether the keyboard and mouse are included.

5. CHIFENCHY bluetooth speaker with induction phone stand

The CHIFENCHY is a small speaker with a built-in phone stand. The listing is marked as 'Amazon's Choice' and a 'limited-time deal'. Per the seller, it has two modes: inductive sound boosting without pairing and Bluetooth audio.

Key features and specs

• Output: 15 watts, surround audio output
• Modes: Inductive sound boosting, with no pairing needed, and Bluetooth
• Stand: Built-in, holds a phone upright

Performance

The stand helps you view your phone in an upright position without using your hands, while the speaker makes it loud. According to the description, the inductive mode does not require any pairing, although it fails to describe how this happens; therefore, you should consider it the seller's claim. When it comes to music and wireless, Bluetooth is the way to go.

Pros

• Phone stand and speaker in one
• Works with or without Bluetooth pairing, per the seller
• 15W output rating

Cons

• Cannot charge a phone
• Battery life and power source are not stated
