Le headphone yokukhansela ingxolo iphezulu kwiklasi yayo
I-Bose QuietComfort 15 yayisexesha elide lomsindo-ukukhansela i-headphone kuba isandi sawo sokukhansela sasingcono kakhulu kunanoma ubani, kwaye savakala. I-Bose yatshintsha indawo ye-Quiet Comfort 25 ngo-2014, i-headphone ebiza ixabiso elifanayo kwaye inika into entsha: I-QC25 isebenza kwindlela yokunyusa xa ibhetri yayo ihla, leyo i-QC15 ayizange iyenze.

INguqulelo entsha yeNqanaba leMashishini
UBose uthi i-QC25 izandile kakuhle, zikhululekile kwaye zenziwe kwizinto eziphezulu eziphezulu kunye nokugqitywa okungcono kunabakuqalayo. I-QC25 ivela kwimeko ehambelana ngakumbi neyona ehlinzekwe yi-QC15. Inayo ikhebula elitsha elichithwayo elinikezelayo ngentaba ye-clunky ye-bayonet kwi-QC15.

Bose QC25: Izixhobo kunye neErgonomics
Izinto zeBose QC25 ziquka:
- 4.5 ft / 1.4 m intambo efunyanwayo kunye ne-iOS-ehambelanayo mic / kude
- Ingxolo esebenzayo yokukhansela kunye nomtshini wokuvala / ukuvala
- Enye ye-AAA ibhetri efunekayo
- Imodi ye-Passive xa amabhetri ehla
- Icandelo lokuthwala libandakanya
- Ubunzima: 6.9 oz / 196 g
Njengoko ungazixelela ukusuka kwisithombe, i-QC25 ngakwesobunxele iyafana ne-QC15 ngakwesokudla.
Into ebalulekileyo apha kukuba i-QC25 isasebenza xa ibhetri ibonakala. Kwakhona, ityala layo lincinci, liphindwe ngaphezulu kwaye lilula ukuba lingene kwisikhwama sekhompyutha.
Ukuziva kunye nentuthuzelo yee-headphone zombini zifana, kwaye zilungile kuba ezi ntlobo zeefowuni zikhululekile ngakumbi kunanoma yimuphi umqhubi wazo. Ngokuphathelele isandi, kunzima ukubetha. Ukuqhayisa ingxolo yeBose ukukhansela kunzima kubakhuphiswano kuba inkampani inemvume yamalungelo amaninzi kule nkqubo.

Bose QC25: Ukusebenza
I-QC25 ne-QC15 zininzi ngokufanayo kunokuba zihlukile. Ukwahluka okukhulu kusezantsi. I-QC25 ibonakala ibe nenqanaba elinamandla elinamandla kwiindawo eziphantsi, mhlawumbi malunga ne-40 ye-hertz kunye neezantsi, ezinika isigubhu sokukhaba kunye namanqaku angaphantsi kwinqwelo yegitala ngaphezulu kwe-dynamics ne-punch. Oku kwenza i-QC25 isandile nje nje nje into enjengeyonto into eyenza i-Beats izenze.
I-QC25's low bass boost ibonakala ichaphazela i-midrange esezantsi, nto leyo eyenza amazwi avele enzima. Kukho ukubonakala okubonakalayo kwimveliso engezantsi, kwindawo ethile malunga ne-2 okanye i-3 kHz.
I-headphone ze-Bose azizange zenze i-rep for sounding-detailed or detailed information. I-QC25 eneenqwelomoya ezinamandla kunye neziqhelo zenza isandi sibonakale sisincinci.
Imodi ye-QC25 yokunqamla isandi ukukhishwa kwembonakalo kwakubonakala ingenasiphelo kwaye inqabileyo, ngaphandle kweenkcukacha okanye ubunzulu, kodwa ivakale kakhulu kunokuba iifowuni zibonelela.
Kwi-flight25, umsebenzi we-QC25 unomsebenzi omkhulu wokuphelisa i-droning yeenjini ze-jet kunye nomsebenzi ofanelekileyo wokunciphisa ingxolo yenkqubo yokuphucula umoya kunye nezinye iingxoxo zabagibeli.

Imilinganiselo: Ukuphendula ngokuphindaphindiweyo
Ishati ibonisa impendulo ye-QC25 kwiimpawu zangasese nakwesokudla, ngomsindo okhanselayo kwaye ucima. Akukho nto ephawulekayo kwimpendulo ngomsindo okhansela. Ngokufanelekileyo "yincwadi ethi" impendulo yekhandaphone akufanele ibe nembala emibala. Kucacile ukuba, isandi sahluke kakhulu ngomsindo okhansela; ine-bass deep, i-midbass kunye ne-bottom bass, kwaye -5 ukuya kwi -10 dB ngaphantsi kwempendulo.

Imilinganiselo: Imodi yeNC esebenzayo kunye neNkqubo yePassi kunye ne-QC15
Le tshathi ifanisa impendulo ye-QC25 ne-NC kunye neNC ngaphandle kwe-QC15 nge-NC. (I-QC15 ayisebenzi kunye neNC ngaphandle). Izilinganiso zeNC zibhekiswe kuma-94 dB kwi-500 Hz. Ngokucacileyo, i-QC25 yabelana ngeziganeko ezininzi ze-acoustical ne-QC15. Umzekelo omtsha unamazantsi aphantsi, amandla amancinci angaphantsi kwe-1 kHz, kwaye isibini seDB esiphezulu kwamandla angaphezu kwe-2 kHz. Kucacile ukuba i-QC25 ye-mode (NC-off) imvo izandile ezahlukeneyo kwiifowuni kwindlela yokusebenza (NC-on).

Imilinganiselo: Ukuzimela
Le tstshi ibonisa ukuhlukaniswa kwesiteshi se-QC25 kunye neNC off (ulandelelwano oluhlaza) kunye ne-NC kwi (umtsalane obomvu), xa kuthelekiswa ne-QC15 (umkhondo we-orange). Amanqanaba angaphantsi kwe-75 dB abonisa ukunyanzelwa kwengxolo engaphandle-umzekelo, 65 dB kwitshathi kuthetha ukunciphisa -10 dB kwizandi ezingaphandle kweso sandi. Umgca wezantsi usetshati, ngcono.
Zombini iifowuni zihambisa ingxolo yokukhansela. Nangona kunjalo, i-QC25 ayibonakali, ubuncinane kule myinge, ukuphucula ngokubanzi ukusebenza kwe-QC15. Kubonakala ngathi i-QC15 iphakathi kwe-200 ne-600 i-Hz.

Imilinganiselo: Ukubola kweSectect
Le tstshana ibonisa ukubola kwe-spectral (okanye i-waterfall) isicwangciso se-QC25 nge-NC. Imijelo emide eluhlaza eluhlaza ibonisa ama-resonances abalulekileyo. Oku kubonisa inani elincinci le-resonance kwi-bass, kodwa i-resonance eqinile malunga ne-1.35 kHz.

Imilinganiselo: Ukuphazamiseka nokunye
Eli grafu ibonisa ukungaziphambuki kweH125 ukulinganiswa kwi-90 kunye ne-100 DBA. Lawa manqanaba aphezulu kakhulu okuphulaphula-awuyi kuphulaphula loo mqulu. Ukuphazamiseka kukuphakamileyo, nangona kunjalo kakhulu kwii-frequencies eziphantsi. I-curve ye-90 ye-DBA ifaneka ngokuqhelekileyo ekungabikho ukuphazamiseka phakathi kwee-mids kunye ne-treble kunye nama-4 ekhulwini kwi-Hz kwi-20. Kwi-100 dBA, kukho ukuphazamiseka kweentambo phakathi kwe-2 ne-3 kHz, kunye nokuphambukiswa kwe-bass (iipesenti ezi-3 kwi-60 Hz nangaphantsi, ukunyuka ukuya kuma-6 ekhulwini kwi-20 Hz). Ngaba uyayiva le nto? Mhlawumbi akunjalo. Umngcipheko wokuphazamiseka okuvakalayo kwisilingo se-subwoofer ngokuqhelekileyo uthathwa njenge-10%.
Impendulo yentsholongwane yatshintshitshulwa nomthombo wesigxina esiphezulu (impumulo ye-75 ohms), ebonisa ukuba uyakuva ntoni xa usebenzisa i-headphone amp-quality efana neyakhelwe kwii-laptops ezininzi. Iibhasi zahla malunga ne -4 dB kwi-20 Hz, kwaye ihamba nge--1 dB ngaphezu kwe-4 kHz. Ngokucacileyo, uBose wenza into encinane apha apha.
Ngobuzwe obunama-32 ohms, lalinganiswa nomqondiso we-1 mW phakathi kwe-300 Hz kunye ne-3 kHz kwi-32 ohms impedance, ngu-97.2 dB kwimodi engekho (NC-off) kunye no-101.3 dB kwimodi esebenzayo (NC-on). Kwanele ukuba unike umthamo ophezulu kunoma yimuphi umthombo nge-NC, kwaye uwanele kuzo zonke kodwa izinto ezinobuthakathaka kunye neNC off.

Bose QC25: I-Final Take
I-QC25 ilungile kunokuba isandulela ngaphambili ngeendlela ezintathu: Ibukeka ipholile, ityala layo lincinci, kwaye livelisa isandi nangona ibhetri ihla. Ukususela kumbono wokusebenza, kubonakala ngathi kufana nokuxhaswa kwemigangatho ye-QC15.
